From Slides to Slides: Thoughts on Teaching with Images

I recently read an obituary of Dennis Austin, the inventor of PowerPoint. I must admit, that although I’ve used PowerPoint for years, I never thought about it having an inventor. If I’d thought about it at all, I probably would have assumed that it was developed by a team at Microsoft. Wrong on both counts—it was just two guys, Dennis Austin and his colleague Robert Gaskins, who created what was originally called “Presenter” in 1987 while working at a company called Forethought (which was then bought by Microsoft later that year). The first Windows version was released in 1990.

My learning about the origins of PowerPoint was timely, because my recent retirement and the resulting need to empty my office of 35 years of accumulated books, files, and other teaching materials has occasioned me to look back on my career. One of the items I found tucked away on an upper shelf was an empty Kodak slide carousel, which got me thinking about my experiences with visual materials in the classroom, both as student and teacher, in the days BP (Before PowerPoint). Of course, my art history professor at Santa Clara University, Brigid Barton, used slides every day. Her classroom was equipped with not one but two slide projectors, so she could display two images side-by-side for comparison. She was an expert at both filling her carousels and at knowing when to advance each projector so that the correct images were displayed.

Kodak Slide Carousel

I also remember her telling us that her husband had visited her classes one day and noticed that the students near him had their heads down, writing in their notebooks only the “vital statistics” of the artworks (artist, title, medium, date) and nothing about what Dr Barton was saying about the significance of the image, which they weren’t looking at. As soon as she learned this, she started handing out a numbered slide list at the beginning of each class, allowing for more effective note-taking and, more importantly, more effective looking.

Whereas slideshows were expected in art history classes—“art in the dark,” as they’re known to students—they were much less common in my other classes. The exception was a Cornell University graduate school history course on Ancient Greece taught by Barry Strauss, for which I was a TA. Like Professor Barton, Professor Strauss used slides in virtually every class. But unlike in art history, where the artworks are the main course content and the entire class period consists of looking at and talking about the slides, Professor Strauss might have just a few slides in his carousel that he would use to help elucidate the topic of the day (one of my jobs as TA was to advance the slides on his command).

The one that sticks out in my memory was in a lecture on fifth-century Athenian democracy. The Athenians had a practice whereby they could vote into a ten-year exile someone they feared might become a tyrant. The ballots for this election were broken pieces of pottery, on which the voters would scratch the name of the person they wished to exile. The ancient Greek word for a broken piece of pottery was ostrakon (plural ostraka), from which we get the words “ostracize” and “ostracism.” Archaeologists have found many of these ostraka with names of prominent Athenian politicians scratched into them. The day Professor Strauss lectured on the workings of Athenian democracy, he showed a picture of these ostraka, which made the concept both clear and memorable.

A collection of ostraka

When I started teaching my own classes while still in grad. school, I took Professors Barton and Strauss as two of my role models, wishing to use images as effectively as they did. Accordingly, I made an effort to build up my own personal slide collection. In 1984, I took a summer course in medieval religious history held in Assisi, Italy; there, I bought slides of the frescoes in the basilica of San Francesco, attributed to Giotto, that I planned to use when teaching the life of St. Francis (fortunately, the lira was weak against the dollar that summer). A couple of years later, my husband and I honeymooned in England, and I used slide film to capture images in Colchester, Lincoln, and York that I would be able to use in a course on Medieval Cities that I was scheduled to teach that fall.

But once I began teaching full-time at Mount St. Mary’s University, I was hindered in my desire to enhance my courses with images by a limited slide library at my new institution. I was often reduced to expedients like holding a book open to the relevant color plate, and then passing it around the room. This lack of access to images became critical in 2000 when we implemented a new core curriculum that included a required interdisciplinary humanities course, titled “Origins of the West,” to be taught by faculty in history, literature, and the arts and incorporating content from all those disciplines. Now we not only needed a greater selection of slides of art and architecture; we needed them in multiple copies for multiple instructors.

Fortunately, I had just taken a technology workshop in which I made my first PowerPoint, on the Parthenon. I realized that this new technology would let me do everything I needed. I could take all the images I wanted from the internet (no need to buy slides); put two images next to each other on the same slide (no need for two projectors); and include identifying information directly on the slide (no need for a separate slide list). And when it was done I could share it with my colleagues (no need for multiple slide sets).

The Parthenon

My first presentation was on the Parthenon; I was still using a much-revised version of it when I retired. I subsequently made hundreds more—the computer folder where I save them currently contains 1638 files (although some of these are probably duplicate versions of the same presentation, or files students sent to me to accompany their class presentations). Among these 1638 PowerPoints are one on Athenian ostracism with pictures of ostraka; one on the Life of St Francis using jpgs of the Giotto frescoes instead of the physical slides I bought back in 1984; and one on medieval cities that includes a scan of one of the photos I took on my honeymoon.

I know that PowerPoint has the reputation of being deadly dull (just google “PowerPoint cartoons” for plenty of satirical takes on this reputation). But I assure you, mine are brilliant. I used to do an activity when I taught our first-year seminar in which I directed students first to make a bad PowerPoint and then to present it badly. They had lots of fun with this assignment—illegible fonts! too-small type! insufficient color contrast! distracting animations! reading bullet points verbatim with your back to the audience! Hopefully, it taught them, and reminded me, what not to do.

Apart from these design considerations, however, the most important rule is not to think, “I need to make a PowerPoint; what should I put in it?” but rather, “I want to present some material that is best understood visually; how can PowerPoint help me do that?” So thank you, Dennis Austin, for making it possible for me to do that.

“Stuff I Did”: The Res Gestae, Tulips, and Squeezes

We tend to think of the Latin language as fancy, formal, and technical. But my favorite Latin word when I am teaching ancient Roman civilization in Origins of the West is “res,” which means “thing.” In Origins, we encounter it in the term res publica, literally the “public thing,” which began, according to tradition, in 509 BCE, when the Roman people, led by Brutus the Liberator, exiled King Tarquin the Proud and replaced the monarchy with a republic. A monarchy is a private thing—the king treats the kingdom like he owns it—but a republic is a public thing, owned by the people as a whole.

We also encounter the word when we read Vergil’s Aeneid, which begins in medias res—in the middle of things.1 Book one of the Aeneid begins with Aeneas already in Carthage; we learn the previous events, the fall of Troy and his voyage to north Africa, through flashbacks, as Aeneas narrates them at the banquet Queen Dido throws for him in books two and three. By book four, we’re back to the present.2

I made this diagram to illustrate how the Aeneid is structured in medias res. The numbered items on the outside of the arch are the events in the order they occurred; the book numbers on the inside of the arch are the order in which we read them.

Finally, my favorite use of my favorite Latin word is in the phrase res gestae, or “things done.” This is the title of a document written by the emperor Augustus (63 BCE-14 CE) near the end of his life.3 The title is usually translated “accomplishments” or “achievements,” but it basically means “stuff I did.” So we’ve got “public stuff,” “in the middle of stuff,” and “stuff I did.” So much for fancy, formal, and technical.

We know of the existence of the Augustus’ Res Gestae from a passage in the biography of Augustus by the ancient Roman author Suetonius, written around 120 CE. Suetonius tells us that Augustus compiled a list of his accomplishments and arranged for them to be published on bronze tablets to be erected in front of his mausoleum in Rome.4

The bronze tablets no longer survive, but a copy that was sent to the provinces does. The Latin text of the Res Gestae is carved into the interior walls of the cella (the inner room) of the Temple of Augustus in what is now Ankara, Turkey (then Ankyra, provincial capital of Galatia). A Greek translation is found on the exterior wall (which makes sense, as Galatia was in the Greek-speaking part of the empire). The inscription is also known as the Monumentum Ancyranum.5

The ruins of the Temple of Augustus in Ankara. Only the cella is still standing.

I use a translation of this text whenever I teach the Age of Augustus. It’s a rare example of an extant ancient historical text that is not only contemporary with its subject but also written by the person in whose voice it is. (Unlike, for example, the Suetonius biography, written about a century after Augustus died, or the Funeral Oration of Pericles, written by Thucydides in Pericles’ voice.)

A portion of the Latin inscription of the Res Gestae on the wall of the Temple of Augustus.

In the document, Augustus lists the achievements he wishes to be remembered by. It’s a combination of a memoir, curriculum vitae, and a completed to-do list. The document is not particularly well-organized, but if we were to reorder the items and group them under headings (which is what I have my students do), they might look something like this:

  • Military Victories and Conquests
  • Diplomacy and Peacemaking
  • Public Works
  • Donations
  • Restoration of the Mores Maiorum (the “ways of the ancestors”)

If you are familiar with the scene in Monty Python’s Life of Brian where John Cleese’s character asks, “What have the Romans done for us,” you might think of the Res Gestae as Augustus’ answer to the question, “What has Augustus done for us?” And both answers would include “the aqueduct” and “brought peace.”

Equally as fascinating as the document’s content is the story of how it was found. I knew that it survived only in the provincial copy carved into the Temple of Augustus in Ankara, and I knew that at some point it was recognized as the work of Augustus. Beyond that, I vaguely assumed that it had been identified by a classically-educated nineteenth-century British diplomat—like Lord Elgin, only less destructive.

As usual, I was partially right. My instincts were correct, but I was off on the details (just like with King Arthur flour). It wasn’t a classically-educated nineteenth-century British diplomat; it was a classically-educated sixteenth-century Flemish diplomat. Ogier Ghiselin de Busbecq (1522-1592) was ambassador of Emperor Ferdinand of Austria to Emperor Suleiman the Magnificent. During his time there, between 1554 and 1562, Ghiselin de Busbecq traveled around the Ottoman empire and later published his observations in Turkish Letters (1581). He wrote,6

Here we saw a very beautiful inscription, containing a copy of the tablets in which Augustus gave a summary of his achievements. We made our people copy as much as was legible. It is engraved on the marble walls of a building now ruinous and roofless which formerly may have formed the official residence of the governor. As you enter the building one half of the inscription is on the right, and the other on the left. The top lines are nearly perfect; in the middle the gaps begin to present difficulties; the lowest lines are so mutilated with blows of clubs and axes as to be illegible. This is indeed a great literary loss, and one which scholars have much reason to regret; the more so as it is an ascertained fact that Ancyra was dedicated to Augustus as the common gift of Asia.

Ogier Ghiselin de Busbecq

 Recognizing the Res Gestae wasn’t Ghiselin de Busbecq’s only accomplishment. He was also interested in plants, and claimed to have been the person who introduced tulip bulbs to Europe. This claim was an exaggeration, but Ghiselin de Busbecq probably contributed to their popularization. 7 Tulips became so popular in the Dutch Republic of the 17th century that the buying and selling of the bulbs is referred to as “Tulipmania,” and the rise and subsequent collapse of the market in 1637 is considered an early example of an investment bubble. 8

‘Still Life with Flowers,’ 1639, by Hans Bollinger (fl. 1623-1672), now in the Rijksmuseum, Amsterdam. The striped tulips, known as ‘broken,’ were the most highly sought-after during the tulip craze. It is now known that the ‘break’ is caused by a virus. Coincidentally, the name of the most valuable broken variety was ‘Semper Augustus.’

The surviving copy of the Res Gestae was mentioned by classical scholars a few times in the subsequent centuries, but serious study of it was only undertaken in the nineteenth century, beginning with the work of Theodor Mommsen, a groundbreaking German historian of ancient Rome. Mommsen was not an archeologist, and he did not travel to Turkey to study the inscription in person. Rather, he relied on drawings made by others to produce his scholarly edition of the Res Gestae in 1865, and a second edition that utilized plaster casts of the inscription in 1883.9

Another technology that has been developed by epigraphers (people who study inscriptions) is known as “squeezes.” A squeeze is made by pressing dampened paper onto the inscription, letting it dry, then lifting it off. The resulting impression is lightweight and easy to work with (although the image is reversed; epigraphers have to become adept at reading ancient languages backwards). Taking a squeeze allows for prolonged study of the text off-site, and for simultaneous study of inscriptions from multiple sites.

I was delighted to learn that Cornell University, my doctoral institution, has an extensive collection of squeezes, including the Res Gestae. The Res Gestae squeeze was obtained as part of the Cornell Expedition to Asia Minor and the Assyro-Babylonian Orient (1907-1908). I was not aware of this collection’s existence while I was studying there, although ancient Greek and Roman history was one of my minor fields. At that point, in the pre-digital era, the squeezes were just sitting in storage in the attic of Goldwin Smith Hall, home of Cornell’s Classics department. But the squeezes have since been restored and digitized.

One of the squeezes of the Res Gestae now in Cornell’s collection.

Another Cornell connection to the Res Gestae, slightly more tenuous, is that Theodor Ernst Mommsen (1905-1958), grandson of Theodor Mommsen, taught medieval history at Cornell beginning in 1954 (having escaped Nazi Germany in 1935) until his untimely death from suicide in 1958. His successor was Brian Tierney, with whom I studied.

In the 1930s, archeologists excavated the Ara Pacis, an Augustan monument mentioned in the Res Gestae10

When I returned to Rome from Spain and Gaul, having settled affairs successfully in these provinces, in the consulship of Tiberius Nero and Publius Quinctilius [13 BC], the senate decreed that an altar of Augustan Peace should be consecrated in thanks for my return on the field of Mars, and ordered magistrates and priests and Vestal Virgins to perform an annual sacrifice there.

As part of his program to connect his rule to the glories of imperial Rome, Mussolini had a museum constructed to house the Ara Pacis, located near the ruins of the mausoleum of Augustus on the banks of the Tiber. The text of the Res Gestae was carved into an exterior wall of the museum. The Ara Pacis museum opened in 1938, a year celebrated as the 2000th anniversary of the birth of Augustus.11

The Mussolini-era museum has since been demolished and replaced with a new building, completed in 2006, designed by American architect Richard Meier. The wall with the Res Gestae was preserved, however. So if you want to see an inscribed version of the Res Gestae, there’s no need to visit Ankara; there’s one in Rome, near its original location, although not on a bronze tablet.

Whenever an academic administrator asks me for the goals of a course, I always use the same three (polished a bit more for administrative consumption):

  • Teach them stuff (content).
  • Teach them to do stuff (skills).
  • Teach them how it relates to other stuff (connections).

The Res Gestae is a perfect example of this approach in action. Teach them stuff: the document is literally made up of, and named for, the stuff Augustus did. Teach them to do stuff: in addition to the skill of reading and interpreting a document, the Res Gestae also gives students the opportunity to learn about disciplines like archeology and epigraphy and techniques like squeezes that lie behind the conveniently anthologized, printed, translated text in front of them. Teach them how it relates to other stuff: the history of the Res Gestae not only connects to the history of the interest in and study of the classics—by Ghiselin de Busbecq in the 16th century, Mommsen in the 19th, and Mussolini in the 20th—it also, more unexpectedly, connects to the history of horticulture and early-modern capitalism. No wonder it’s one of my favorite texts to teach.

Reclining Madonnas: Changing Iconography of the Nativity of Jesus

Every year when I teach Gothic architecture in Origins of the West,1 I spend two classes on Chartres cathedral. The first day is devoted to the architecture; the second to the decoration, in both sculpture and stained glass. For sculpture, I focus on the west portal, specifically on the Portal of the Incarnation. This consists of a large tympanum featuring the Madonna Enthroned with Angels, surrounded by archivolts with personifications of the 7 liberal arts (one of the reasons I chose this particular portal).

The Portal of the Incarnation, on the west facade of Chartres cathedral.

Below the tympanum are two lintels with scenes from the life of Mary and Jesus. In the bottom register, from left to right, are found the Annunciation, the Visitation, the Nativity, and the Adoration of the Shepherds.

Closeup of the lintels. The Circumcision of Jesus is in the upper register, in the center. In the lower register, reading left to right, are the Annunciation, the Visitation, the Nativity (center), and the Adoration of the Shepherds.

Today (naturally) I want to concentrate on the Nativity.

Detail of the Nativity in the Portal of the Incarnation, Chartres Cathedral.

Notice the iconography: Mary is reclining on a low couch underneath what looks like a dining room table; a swaddled Jesus sits on top of the table; Joseph stands to the left and an angel is on the right. One of the things I point out to my students is the Eucharistic imagery of putting the body of Jesus on a table—especially since the scene directly above, in the upper register, is the Circumcision, where the infant Jesus is cut (and presumably bleeds) by a priest at an altar.

What I always found curious, however, is the representation of Mary lying on the bed. Mind you, this would have been a sensible thing for her to do, having just given birth. For a long time I assumed that this iconography was unique to this sculpture, but then I discovered that Mary is in the same reclining position in the Incarnation window, a stained-glass window in the west façade of the cathedral.

So maybe it was a regional peculiarity, I thought. After all, I know what Nativity scenes look like—I’ve got one that I set up every year, that was given to my mother as a child. Maybe you have one too, or you’ve seen them set up in churches or parks.  Mary is always depicted kneeling, looking down at her child, who is lying in a manger set on the ground.

My nativity scene, given to my mother when she was a child.

My regional hypothesis was disproved, however, when I discovered another instance of a reclining Madonna in the Nativity scene in the Sienese painter Duccio’s Maestà altarpiece of 1308. In this one, she appears to be resting on a giant red beanbag chair (ok, I guess it’s probably a blanket or a cloak). A google image search turns up further medieval examples.

So it appears that it was quite commonplace in the Middle Ages for Mary to be depicted lying down after the birth of Jesus. How do we account for my mother’s Nativity set, then? When and why did the iconography of the Nativity change from the reclining Madonna to a kneeling Madonna?

The answers are, in the late 14th century, and because of St Birgitta of Sweden.2 Birgitta Birgersdottir was born into the Swedish nobility in 1302 or 1303. She married Ulf Gudmarsson at age 13 and bore 8 children. After her husband’s death, she felt called to a spiritual life and began having revelations, which were recorded by her confessors. She made a pilgrimage to Rome in 1350 and remained there, never returning to Sweden. Like her contemporary Catherine of Siena (whom she probably never met), she was a prophetic voice for the reform of the Church, in particular advocating for the return of the papacy to Rome from Avignon.3

In 1372, the year before she died, Birgitta made a pilgrimage to the Holy Land. In Bethlehem, she had a vision of the Nativity of Jesus, described in book VII of her Revelations:

. . . the Virgin knelt with great reverence, putting herself at prayer, and she kept her back toward the manger and her face lifted to heaven toward the east. And so, with raised hands and with her eyes intent on heaven, she was as if suspended in an ecstasy of contemplation, inebriated with divine sweetness. And while she was thus in prayer, I saw the One lying in her womb then move; and then and there, in a moment and the twinkling of an eye, she gave birth to a Son, from whom there went out such great and ineffable splendor that the sun could not be compared to it. . . . I saw that glorious infant lying on the earth, naked and glowing in the greatest of neatness. . . .

When therefore the Virgin felt that she had now given birth, at once, having bowed her head and joined her hands, with great dignity and reverence she adored the boy and said to him: “Welcome, my God, my Lord, and my Son!”

From Birgitta of Sweden: Life and Selected Revelations, ed. Marguerite Tjader Harris, trans. Albert Ryle Kezel, Classics of Western Spirituality (New York: Paulist Press, 1990), p. 203.

Here we find the familiar setup: Mary on her knees gazing down at her newborn child. I was surprised to read that in Birgitta’s vision, she saw Mary actually give birth in the kneeling position; I had assumed that it was postpartum.

The new iconography based on Birgitta’s vision did not take long to show up in Italian art. One of the earliest representations, by Niccolo di Tommaso (d. 1376), depicts Birgitta herself (in the lower right corner) in the act of having her vision.

The Nativity with St Birgitta of Sweden, by Niccolo di Tommaso,. Now in the Pinacoteca in the Vatican.

Another early example, by Lorenzo Monaco, dates to 1406-1410. In this representation we also see the baby Jesus glowing with “great and ineffable light.”

Nativity by Lorenzo Monaco, 1406-1410. Now in the Metropolitan Museum of Art, New York.

By the 15th century, the iconography of the kneeling Madonna had become standard. But someone ought to produce a set of Nativity figurines featuring a reclining Madonna—I think there would be a market for it.

Horses on the Wall? A Delightful Dickensian Discovery at the V & A

Last summer my husband and I traveled to the UK for a family wedding and combined it with a brief vacation. Having just binge-watched the mini-series Victoria before we left, the Victoria and Albert Museum (the V & A) was a must-see.

We were thrilled to discover a small special exhibit in celebration of the bicentennial of both Victoria’s and Albert’s 1819 births entitled “Building the Museum.”1 The exhibit chronicled the role of the Queen and the Prince Consort in the planning of the Great Exhibition of 1851 (also known as the Crystal Palace) and how the V & A grew out of it. We’d just seen the Victoria episode on the Exhibition, so this was perfect. We must have looked interested, because a docent stationed in the gallery came over to us and gave us an impromptu tour.

One of the things we learned was that Henry Cole, who organized the Great Exhibition, was also the first director of what became the V & A. Cole saw the mission of the new museum as educational, and part of that mission was to elevate the taste of the public. To that end, he put on an exhibit in 1852 called the “Gallery of False Principles” that provided both good and bad examples of design (the press referred to it as the “Chamber of Horrors”). The “False Principles” included decorating a home with representations of objects rather than the objects themselves. For example, one of the items in Cole’s original exhibit also included in the”Building the Museum” exhibit was a sample of wallpaper printed with a pattern of Gothic architectural ornamentation. This is a “false principle” because the papered wall doesn’t really have Gothic ornamentation on it but only a printed representation of it.

Another example, our docent explained, would be a flowered carpet. At that point I interrupted her, saying, “It’s just like that scene in Dickens’ Hard Times where the government official tells the students that they shouldn’t have flowered carpets or wallpaper with horses on it!” The docent responded excitedly, “Wallpaper with horses was one of the examples!”

I teach Hard Times every fall in my modern European history class. The novel, first published in 1854, is set in Coketown, a fictional northern English industrial city. Hard Times opens with a scene in a school founded by Mr Thomas Gradgrind, a wealthy industrialist who believes in teaching only Facts.2 Gradgrind, along with an unnamed visiting government official (referred to only as “the gentleman”), is visiting a class taught by Mr M’Choakumchild.3 The gentleman asks the students,

“Would you paper a room with representations of horses?”

Some say yes, some no, whereupon the gentleman explains,

“Do you ever see horses walking up and down the sides of rooms in reality—in fact? Do you? . . . Why then, you are not to see anywhere, what you don’t see in fact; you are not to have anywhere, what you don’t have in fact. What is called Taste, is only another name for Fact.”

In case the children didn’t get the point, he poses another question:

“Would you use a carpet having a representation of flowers upon it?”

One of the students, Sissy Jupe, daughter of a circus clown, says she would. When the gentleman asks her why, she says,

“If you please, Sir, I am very fond of flowers.”

“And that is why you would put tables and chairs upon them, and have people walking over them with heavy boots?”

“It wouldn’t hurt them, Sir. They wouldn’t crush and wither, if you please, Sir. They would be the pictures of what was very pretty and pleasant, and I would fancy—”

“Ay, ay, ay! But you mustn’t fancy,” cried the gentleman, quite elated by coming so happily to his point. “That’s it! You are never to fancy.”

This opening scene sets up the conflict between Fact (represented by Gradgrind and his school) and Fancy (represented by Sissy and the circus) that drives the rest of the novel. (Spoiler alert: Fancy wins.)

I was very pleased to be able to show my students this fall the photo I took of the objectionable Gothic wallpaper. I couldn’t take a photo of the equestrian wallpaper, as it wasn’t included in the “Building the Museum” exhibit, but I have since found it in their collection.

I had always assumed that the nameless government inspector who intimidates poor Sissy Jupe was exaggerated to the point of absurdity in order for Dickens to make his point about the weaknesses of an education based solely on Fact. I was stunned, but delighted, to learn that the character was not an exaggeration but was, if you’ll pardon the expression, based on fact—a thinly disguised version of Henry Cole. The inspector’s closing remarks could easily have been spoken by Cole:

“You are not to have, in any object of use or ornament, what would be a contradiction in fact. You don’t walk upon flowers in fact; you cannot be allowed to walk upon flowers in carpets. You don’t find that foreign birds and butterflies come and perch upon your crockery; you cannot be permitted to paint foreign birds and butterflies upon your crockery. You never meet with quadrupeds going up and down walls; you must not have quadrupeds represented upon walls. You must use,” said the gentleman, “for all these purposes, combinations and modifications (in primary colors) of mathematical figures which are susceptible of proof and demonstration. This is the new discovery. This is fact. This is taste.”

Having served his philosophical and narrative purpose, the gentleman from the government with the limited taste in wallpaper does not appear again in the novel. Maybe Dickens didn’t give a name to the character because he knew that 1850s readers would recognize him as Henry Cole–and now you can, too.

Renaissance Gettysburg

One gorgeous summer afternoon a few years ago, while in Gettysburg, PA for a chamber music camp, I used our afternoon break from playing string quartets to visit the Gettysburg National Military Park and take some photos. I stopped the car at the most prominent monument I could see, which turned out to be the Pennsylvania Monument.

As I was walking around it looking for good photographic angles, I noticed how the summer sky was framed by the monument’s arch. “That’s beautiful,” I thought. “It looks just like a painting.” Then I realized, “Hold on—it looks like THE painting.” A quick search on my phone confirmed my suspicion. The Pennsylvania Monument is indeed very similar to the architectural setting of Raphael’s 1509 fresco The School of Athens, right down to the sky framed by the arch. (The other tourists visiting the Battlefield that day probably wondered why I was jumping up and down in excitement).

So, was The School of Athens the inspiration for the design of the Pennsylvania Monument? The monument was commissioned in 1907 by the Pennsylvania state legislature; architect W. Liance Cottrell was awarded the job. (Sculptor Samuel Murray, who studied with Thomas Eakins, got the sculpture commission.) The monument was still incomplete when dedicated in 1910; more money was appropriated and the finished memorial was rededicated on July 1, 1913, as part of the 50th anniversary commemoration of the Battle of Gettysburg.

I have so far been unable to find any evidence that Cottrell had Raphael’s fresco specifically in mind when he designed the memorial to Pennsylvanians who fought at Gettysburg. Cottrell was trained in the Beaux-Arts school of architecture, which made extensive use of classical style. Raphael and Cottrell may simply have chosen the same classical elements for their creations. But I like to imagine that Cottrell tried to bring Raphael’s imaginary building to life on the field of Gettysburg.

Teaching with Produce, Episode 1

I use a lot of images in my classes, especially art and architecture from the time periods we’re studying. It can be challenging, when studying architecture, to visualize a 3-dimensional structure when all you’re looking at is a 2-dimensional photograph. One way of meeting this challenge is by learning to read different kinds of 2-dimensional representations, like ground plans and elevations. Another way is to use 3-dimensional models. And sometimes you can make your model out of produce.

When I teach Renaissance art in a core course on modern Europe, I choose three examples, one each of painting, sculpture, and architecture—all from Florence, all from about 1430, and all one of the first of their kind. So we take a look at Donatello’s David, the first free-standing bronze nude since antiquity;Masaccio’s Holy Trinity, one of the first uses of vanishing point perspective; and Brunelleschi’s Pazzi chapel, an early example of a domed building modeled on the Pantheon.

Unlike the Pantheon, however, where the dome sits atop a round drum, Brunelleschi’s dome sits on a square base. The transition is achieved by means of pendentives, the curvy triangles on either side of the semicircles. This is extremely hard to visualize from a photo alone—so I bring out the grapefruit. I owe this demo to my college art history professor at Santa Clara University, Dr. Brigid Barton (one of my pedagogical role models).

Take one grapefruit, the largest and roundest you can find, and slice it in half. You now have two hemispherical domes; set one aside. Then, with the cut side down, make four vertical cuts in the shape of a square. And voila! You now have a square base transitioning to a round dome, by means of pendentives. Thanks, Dr. Barton!
