House Groups in ArtStor: House of Narcissus

As JJ posted about earlier, some of the initial labor for Phase One involved sorting through the vast archive of 500+ photographs of mosaics from Antioch that the JHU Visual Resources Collection built for us prior to the start of the course. JJ took on the task of grouping those images by house, bringing together within Artstor mosaics that have been distributed around the globe. Within these groups one can now access the available photographs of mosaics, regardless of current location. For now, this resource is limited to those with JHU’s institutional subscription, due to image permissions, but I have extracted some screenshots to share how it works using the example of the House of Narcissus:

And here are some additional images of the Narcissus mosaic from its current location in situ at the Baltimore Museum of Art.

Perceiving Sound in Antioch

Sound perception is a relatively unexplored concept in art historical and archaeological fields of study. The recording arts have only been around for less than a century, and mainly connected to capturing the modern, not the historical. While fields such as archaeomusicology explore the sounds of ancient music, we have little to no perception of sound in everyday spaces. This is due in part to the fact that these spaces don’t exist today. While some important ancient buildings are still standing, the vast majority of residential and commercial spaces were repurposed, destroyed or built upon in the name of progress. Antioch is no different; we may have many of the mosaics from the ancient site, but nothing exists of walls, thresholds or rooves. Furthermore, most of the research on these buildings has understandably been focused on the mosaics remaining. However, through my research conducted during the first phase of the Antioch Recovery Project and through experiments conducted during the projected second phase, I intend to recreate some of the sounds of ancient Antioch using modern settings and technology.
While little is left of the buildings at Antioch, we can use the floor plans and research on contemporaneous buildings to gain a better understanding of how they worked. The buildings were likely made out of stone, which would have likely made the rooms incredibly echoey. This would have made it difficult to hear anything. The warm climate also points away from materials such as wall coverings, which would have helped to dampen some of the sound. However, this warmer climate also would have made possible outdoor and outdoor-adjacent spaces. For example, looking at a floor plan of the house of Menander (Figure 1), we can see that there exist pools and colonnades. Pools in the houses would have been filled by falling rainwater, so it is evident that these spaces were open to the outside. Furthermore, we can make the assumption that other colonnaded spaces would have been open-air as well. This is particularly interesting because these open-air spaces correspond with larger gathering places such as dining rooms and courtyards. These large spaces being open to the outside would help to dissipate some of the echo that we could assume occurred in smaller, closed off rooms. It is also likely that these smaller rooms were probably private rooms (such as bedrooms), where less sound, and thus less echo, would occur.
Now that we have some understanding of how buildings in Antioch might have looked and worked, we come to the question of how to recreate sound in these spaces that no longer exist. There are two types of spaces that we would need to record in: indoor and outdoor-adjacent. While these spaces may not actually exist in situ, certain modern spaces would work as adequate places to record and recreate sound. The first space is the Dumbarton-Oaks museum in Washington, D.C. This space has a collection of many Antioch mosaics displayed on the floors and are open to walk on. This is an exciting prospect for being able to record sound interaction with mosaics themselves. This space would be an adequate recreation of outdoor-adjacent spaces in Antioch houses, as there would be little echo and more focus on the sound of walking over mosaics. In order to get a historically accurate sound, I also propose doing research into authentic footwear of the time to see how sound differs between modern footwear, bare feet, and historical footwear. In order to capture the sounds of indoor spaces, I propose that we record in the Metropolitan Museum of Art in New York City. This museum has preserved rooms from Pompeii (Figure 2) that, while not in the same geographic location or century, are likely extremely similar to the indoor rooms that existed in Antioch. Furthermore, the Museum is extremely open to projects and research as long as there is no damage to the art. This means that we would probably be able to get into the space and record without having to get express permission from the administration. However even if we needed permission, I am sure that the Met would allow us to record. I also propose researching ancient musical instruments to use in this space, as the instruments were likely created to thrive in the echoey qualities of indoor rooms. It would also be interesting to research and recite ancient poetry in these rooms in order to see how they would sound to an ancient ear.
While covid-19 has made it impossible to gather these recordings in this semester, I am thankful that there will be a second phase of this project, so we can gather this data. In my opinion, it is extremely important to understand how sound worked in these spaces, as sound is an integral yet often overlooked part of our lives. Hopefully, this research will also bolster more projects similar to this one and make ancient sound recreation a more explored field.

Pivoting as a Result of Widespread Museum Shutdowns

I began my time with the Classics Lab Antioch Recovery Project with a passion for visitor experience. Our class, interestingly, did not have the makeup of a typical classics course. Rather, it had students hailing from a wide array of disciplines, including mechanical engineering, electrical engineering, economics, anthropology, and art history. These diverse opinions further encouraged me to step outside of my own background in art history and explore how larger sectors of the population engaged with Antioch Mosaics.

I began my study with a wide sweep of internet reviews. I specifically remember scanning one recent Yelp review of the Baltimore Museum of Art from an individual named Jason J, that read: “my personal favorite are the Antioch Mosaics acquired in the 1930s through a Princeton University archaeological excavation. It’s powerful viewing these walls…Which were most likely floors originally. (It does bother me that these are no longer in their original location but I don’t know the circumstances of their removal. It may have been to make way for modern construction or some other reason.)”

The individual’s comments revealed a deep investment in the pieces, as was evidenced in his knowledge surrounding their excavation. However, his confusion was equally as revealing. Although he had clearly visited the Baltimore Museum of Art’s sunny Antioch court, the object labels had not successfully relayed the appropriate information regarding the conditions around the removal from modern day Antakya. With this information in mind, I partnered with my classmate Louisa to design a questionnaire that would probe at these questions: How do different visitors interact with the Antioch mosaics? What information do visitors retain about these objects? What further details would visitors like to learn about the Antioch mosaics? How does the surrounding space and the curatorial decisions affect these outcomes?

Unfortunately, before Louisa and I had the chance to execute our survey on site at the Baltimore Museum of Art, the museum had decided to close its doors to mitigate the spread of the COVID-19 virus. Without the ability to stand with visitors in the space, we decided to pause this line of research and pivot to something more virtual friendly. Louisa cleverly suggested that we flip the research around, instead interviewing curators about their intentions with the Antioch mosaics their respective institutions held. This way, we reasoned, we could understand what narratives curators wished to impart with their work on the mosaics. Although the transition wasn’t always smooth, we hoped that by starting to research curatorial intentions would set up the next iteration of the course to conduct better visitor surveys when museums reopened.

The Roman-Persian Wars: two views on borders

During this semester I was interested in researching the historical and ancient geopolitical situation of Antioch at the time of the mosaics and relating that to the mosaics themselves. This final blog finishes my chronology of the various “border” wars fought during the Roman-Persian wars, between the Eastern Roman Empire and the Sassanid Persian Empire.

The Eastern Roman Empire was first founded as part of Diocletian’s reforms after the Crisis of the Third Century that I mentioned in a previous blog. He split the Roman Empire into the Eastern Roman Empire and the Western Roman Empire with two co-emperors to try to make the empire easier to run. However, his reforms failed and there were more civil wars until Constantine reunified the Empire. Eventually, after even more civil wars, Emperor Theodosius finished the process of dividing the Roman Empire in two by leaving the eastern and western halves to his two sons when he died in 395 AD.

The Sassanid Empire was founded when Ardashir I, who was the satrap, or governor, of Pars (modern day Fars Province of Iran) under the Parthians rose up and overthrew the last Parthian king of kings and proclaimed himself King of Kings of Persia. The mutual hatred between the Roman and Persian Empires that had existed for centuries continued even with this change in government because unlike the previous two Persian Empires, the Sassanid government was less religiously tolerant, more militantly Zoroastrian, more nationalistic (even though nationalism as we know it today did not yet exist) and more religiously conservative. The culmination of all these factors was many persecutions of Christians and Manichaeans under the Sassanids.

This angered the Romans, especially after the Roman empire turned Christian, and it was exacerbated when the Sassanids tolerated Christian sects that the Romans did not like. In their minds, any enemy of Rome was a friend of Persia. The Sassanids also tolerated Jews for the same reason, because Rome had always had a rocky relationship with Jews ever since they first revolted against Rome and the situation got even worse after Rome turned Christian.

This is a map of the Eastern Roman Empire and the Western Roman Empire as they stood at the death of Theodosius in 395 AD.

The Persians captured and recaptured Antioch many times during the course of the Roman-Persian Wars. As a result, as I have already mentioned in an earlier blog, Persian influence was very strongly reflected in Antioch as evidenced by the use of lions and geometric patterns in mosaics. This was also because of the presence of many Persian and other merchants from the Persian Empire that worked on the Silk Road in Antioch. Chinese, Indian, Central Asian and other goods traveled through the Persian Empire to get to Antioch. Its strategic position on the Silk Road and the other trade routes connected to the vast Indian Ocean trade network contributed to Antioch’s accumulation of its vast wealth. Despite the constant conflict around it, Antioch remained a tolerant, multicultural city.

I have talked previously about the acculturation that all of this geopolitical conflict created in the area around Antioch and pointed out the use of peacocks, lions, Greek writing and literature as examples. As I end my chronology with this discussion of the Sassanid Empire, I see the Persian influence in Antioch as reflected in the “borders” of the mosaics. Much like a fine Persian carpet, the mosaics often include layers of borders that frame the interior of the mosaics. Scholars of Persian textiles note this link, too. As Maryam D. Ekhtiar said in Art of the Early Caliphates (7th to 10th centuries), “Artistically, both empires have developed similar styles and decorative vocabulary, as exemplified by mosaics and architecture of Roman Antioch”.

After the Roman-Persian wars, the ancient city of Antioch ended. It was gradually diminished and eventually devastated by a series of earthquakes in 526 and 528 AD. The city went on to be conquered by the Muslims and became a part of the Rashidun Caliphate. This conquest finally ended the Roman-Persian Wars.

I am thankful to my classmates for what I learned from their various perspectives on the mosaics. I am especially thankful to Ella and Maya for what they shared about their efforts to create GIS maps of the existing Antioch mosaics around the world. Their work sparked a modern-day mystery for me—what happened to the Cuban mosaic after the revolution? That remains unsolved, but now when the world returns to its new normal, I will travel to Cuba and try to solve that modern-day mystery myself.

Twisted Ribbon Design and Geometry

The twisted ribbon border is a meandering pattern of what appears to be a flat ribbon waving along across the mosaic in a repeated manner. While there is thought to be no major significance to the pattern itself, it represents “the movement towards ornamental complexity” in the Antioch mosaics, “which was born in the late second century.” The ribbon itself is typically different colors on each side, which are shaded into gradients as it arcs. This paper will focus on the twisted ribbon that transverses sinusoidally, and it identifies some variations of the pattern.

This paper is written for the Antioch Recovery Project, part of the Classics Research Lab at Johns Hopkins University. While I arrive at certain claims through my work, there is no “conclusion” to this topic. This paper serves as a journal surrounding my research into the Twisted Ribbon border pattern. I encourage others to add on or disagree with certain aspects, and perform similar studies to other design elements of the Antioch Mosaics. 

Organization of Mosaics by House and General Trends

After quite a few weeks I’ve finally finished categorizing the images in the Antioch Recovery Project Artstor! A long monotonous task but I’m really glad I did it. I’m the kind of person who can much more easily draw conclusions and make improvements if I can see everything of interest together in one place. By organizing the images such that all mosaics corresponding to the same house, as well as house plans and in situ photographs, are grouped together under the house name, it has become much easier to see why certain things happen.

For example, at the beginning of the project, I wanted to find out why certain houses had very specific names. Like why the House of the Drinking Contest was called that when the mosaic associated with that house in the collection at the Baltimore Museum of Art depicts Psyche stealing from Eros. However, when I was through categorizing the images, it became clear that the House of the Drinking Contest is named for the large mosaic central to the house that shows Heracles and Dionysus in a drinking contest with one another. Now, things like house names seem obvious. Yet a month ago I would not have been able to confidently know things like this without searching through hundreds of images.

Going through the hundreds of images, I began to realize a few things. One of the first things was that at first glance everything felt similar. I just assumed that every mosaic had the same orange-y neutral color pallet and portrayed familiar scenes of Greek mythology.  Yet the more I began to order the images by house, the more distinct each one felt. The Atrium House featured multiple images of satyrs and maenads standing alone surrounded by layers of geometric borders. The House of Dionysus and Ariadne more prominently featured larger geometric patterns and scenes of several people together. The individual images in the Atrium House feel more isolated by the large layers of the border that separate the figures from each other. However, with the images of couples in the House of Dionysus and Ariadne together in series it feels more like it is telling a story. These differences in tone and composition may be easily noticed by an expert, but for me, it took ordering these images by original location to notice what makes each house unique.

While going through the process of categorizing the images was really helpful in familiarizing myself with the various forms on the content present in Antioch and Daphne, I hope that the complete groups will be more useful for future researchers. It has been really fulfilling to see my colleagues use these image groups to generate their own projects, including story maps and house models. I hope that these groups will be used to better understand the similarities and differences between houses, to recreate what the houses looked like in their prime, and to study patterns between houses in the same area. Whatever the direction of the Antioch Recovery Project is in the future, I hope that my contribution not only allowed me to discover clarity but provided a foundation to make new improvements moving forward.

3D Model Construction and Viewing, an Update, pt. 2

In my initial post on this subject, I finished by constructing a test house in Sketchup, and importing that into a basic Unity game, with typical FPS (first person shooter) style controls- moving with WASD, jumping with space, and looking around with a mouse. Since then, the project has advanced in both of those ways: the house and the game.

As previously discussed, while other 3D model viewers already exist, none that I found allowed you to walk through them akin to a game, which I consider to be significantly more immersive than simply viewing it. Thus, I decided to make my own. Since the last post, the basic coding hasn’t changed- movement and vision work the same.

However, I decided to add a new feature- when you looked at a mosaic, I wanted to be able to pop up a screen, displaying both the mosaic from a head-on perspective, and also information about it- such as its name and current location.

A screenshot of the info display within the Model Viewer

This took quite a long time.

In my first attempt, I used the built-in Unity functions of OnMouseEnter() and OnMouseExit() to determine when the cursor was looking at the mosaics- when the mouse entered the confines of a mosaic, code would begin to run, checking to see if the user pressed the “e” button. If they did, then the desired info would all pop up. Once the user pressed “e” again or moved their mouse outside the confines of the mosaic, the information would disappear.

However, while this worked in testing, it didn’t work once the program was built in WebGL and uploaded to the site. This is because for security reasons, browser games can’t move the cursor- thus, the in-game crosshair and the actual mouse didn’t line up, so when the crosshair was hovering over the desired mosaic, the mouse wasn’t, so the code didn’t execute as desired.

To fix this, I had to implement my own method of detection, which was Ray casting. This continually drew a ray from the center of the camera out into the world. I could then detect when that ray hit objects, and which object it hit. Once I knew that, I could check if the object was a mosaic, and if so, it would pull up the info as desired.

The code that displays and hides the Info Display on a key press
The code that handles the ray casting, and general logic of the system

After this, a smaller problem remained- the images and text didn’t scale properly with window and screen size, but this was easily fixed with a settings change.

However, there is still work that can be done. The exact method of embedding the program in the website is still to be decided. Verge3D, an extension for WordPress, allows for direct hosting of the application, as well as easy full-screening. However, so far, I haven’t found out how to host it without the game being partially cut off. Hosting on simmer.io and embedding using <iframe> allows for a cleaner appearance, but may have legal issues of publicly hosting content including non-public images of mosaics, and doesn’t seem to allow for full-screen.

Additionally, further features could potentially be added, allowing for time, such as recreating the real topography of Antioch within the game, so the house would be positioned as it was in real life.

Conservation of Recovered Mosaic at Princeton University

While researching the conservation of the Antioch mosaics, I came across a very interesting case regarding a mosaic placed in the threshold of the Architecture Laboratory at Princeton University. Princeton was part of the excavation team that also included members from the Worcester Art Museum, the Baltimore Museum of Art, Harvard Art Museums, and Dumbarton Oaks. Around 300 ancient Roman floor mosaics were uncovered, and Princeton received a part of the find.

              The lifting process during excavation itself was extremely destructive. The mosaic was first stabilized with interior losses filled with cement and the surfaced was faced with animal glue and cloth. Then the bedding mortar was then disrupted while digging around the mosaic. Blocks were added for structural support. The backing mortar was then removed. A wooden frame was constructed to place iron rebar bars for stabilization, and the back was filled with cement for structural stability.

              The mosaic was rediscovered in 2011 in the vestibule of the Architecture Laboratory where it has been since 1949. It was installed here as part of the renovation of the building and had not been moved after. Being outdoors, the exposure of the mosaic to the elements has left it in poor shape. The conservator working with Princeton was Leslie Gat. The panel was part of a border of a larger piece that was excavated near the House of Phoenix (DH-256 Dig C). The mosaic consists of three heads, the heads on the corner are female and according to Princeton University they think they are possibly masks of maenads. The goal for the conservation was to lift the mosaic out of the ground successfully without inflicting further damage so that work could be done in the conservation studio.

              The concrete curb was removed and revealed that the mosaic was about two inches of concrete thick. Steel slides and Teflon sheets were installed to go under the mosaic to aid with transport onto the pallet where it was strapped down.

              The rebar in the cement corroded and expanded which cased many of the tesserae to be damaged and knocked off. When in the ground, areas that were lifting were covered with cement, which left areas of tough concrete. In areas where it was feasible, the cement was removed where tesserae were found underneath and reinstalled. A plaster fill was then used to cover the empty spaces left by the cement. After, conservation was completed it was reinstalled in one of Princeton University’s buildings.

Conservation of the Mosaics Amidst COVID-19

              Many workstreams on the project have been impacted by increasing measures put in place to stop the spread of coronavirus. Social distancing and travel restrictions have caused numerous public spaces to close as well as schools, universities, and workplaces. Museums have also been impacted by these initiatives which, ultimately, halts any in person interaction with art (and for our purposes the Antioch mosaics). It will also be interesting to see how museums and other art institutions adapt to a more virtual world. Where art museums were mostly a place of physical gathering to exhibit pieces, they must now create ways for visitors to interact digitally. There is also the looming question of how this pandemic will impact funding and focus on the humanities.

              Luckily, before I had to leave campus, I was able to meet with Angela Elliot at the Walters Art Museum. She is a conservator at the museum and had previously worked at the BMA with the Antioch mosaics. It was interesting to discuss her thoughts on the impact of coronavirus on museum visitation (this was before more strict measures regarding public gatherings were put in place).

              It was helpful to gain insight on the day to day work of a conservator and the roles they have within the museum.  Mosaics themselves are stable structures, however conservation projects are expensive. The size and weight of the Antioch mosaics make relocation difficult so they will most likely stay stagnant at the BMA.

              My current workstream is going to lead me to investigating past conservation work done on the mosaics. I have been digitally tracking conservation efforts done to the Antioch Mosaic in order to possibly document the work done on them. It is important to know the decisions conservators have made and the possible impact they have on the viewers’ experience with the mosaics.
