Touching Antiquities: Undergraduate Research puts ancient manuscripts in the hands of the public

Homer’s Iliad is back at the publishing house, but turning these pages involves only a light tap on an iPad screen. With each digital page turn, the Imaging the Iliad iPad app transports the revered, but fragile, Venetus A Iliad manuscript from an inaccessible Venetian library into the hands of students, researchers, and classical enthusiasts around the world.

During the summer of 2007 researchers from the University Of Kentucky Center for Visualization, University of Houston, College of the Holy Cross, Furman University, and Brandeis University gathered in Venice, Italy at the Marciana Library to digitally preserve the Venetus A. Considered by some to be the most important manuscript of the Homeric stories, the Venetus A also contains layers of commentary and annotations, usually attributed to scholars at the Royal Library of Alexandria.

The only previous images had been made in the 1901 by Domenico Comparreti, but the process was highly destructive since the manuscript was sliced apart, placed on glass and photographed, and then rebound. In contrast, the modern process allowed the intact manuscript to be gently placed in a Meyer Conservation Copystand. Page by page, they carefully scanned the ancient manuscript, capturing both high quality digital photos and structured light data to create a 3D model of the surface, which can then be used to digitally “flatten” the manuscript and remove distortions from the text.

The photos were then made publicly available through the University of Houston’s Homer Multitext data archive. But the Vis Center team had plans to use an undergraduate research team to make the Iliad accessible to a much broader audience.

Undergraduate students, Zach Whelchel and Carla Lopez Narvaez did research the summer of 2010 at the UK Center for Visualization. Their assignment was to create an iPad app that would allow the reader to interact with the Venetus A Iliad as well as an English translation. “The project was an ambitious one that was just concrete enough to be possible,” said Whelchel. “Our team was given a lot of space to envision how to best display the folio images.”

The team was given the 3D Iliad images, the corresponding Greek text, and the English text of the Iliad. “The images had already been matched up with corresponding Greek text, but making that correspond with the English transcription was quite difficult, conceptually,” said Ryan Baumann, Vis Center staff who oversaw the student work. Over the course of the summer they worked to create an iPad app that would allow the reader to read the English text side by side with the corresponding folio of the Venetus A. Whelchel said that “to do this we compared two XML documents. The first had the line found on each folio (Ex: Book 1, Lines 32-56) and the second had the entire Iliad (in English) tagged by books and lines.”

“We wanted to build the app as a template that could eventually encompass other texts. Because of this, we took the long route on parsing through the folios to match the lines properly,” said Whelchel, a sophomore Media Communications and Math double-major at Asbury University in Wilmore, KY. “We had to build an intuitive way to ‘page through’ the book. We wanted it to feel like you were actually turning a page so the user could better interact.” Most surprising was “the level of complexity that goes into every page turn.”

Narvaez, a Computer Science student at the University of Puerto Rico – Rio Piedras, said their problem was “how to bring ‘The Iliad’ from the oldest form of print to the newest form of print on the iPad.” Narvaez interned at the Vis Center through the Vis U program, which brings Computer Science undergraduates from the University of Puerto Rico for summer research opportunities in visualization and virtual environments. “This new experience helped me…to work with new people and combine all our ideas…to manage and resolve the problems we found each day during the process of our research and…to keep learning new things,” said Narvaez.

Dr. Chris Blackwell, Classics professor at Furman University was part of the Venetus A imaging team in 2007. As a member of the Homer Multitext project through the Center of Hellenic Studies at Harvard, Dr. Blackwell has worked for over a decade bringing the words of Homer to new life in electronic media. He has found the Imaging the Iliad app to be an exciting means to do just this. “This iPad app is a beautiful example of where all such projects are going, and the pleasant surprises that lie in store. When we started thinking about giving these manuscripts life electronically, no one dreamed of a touch-based, lightweight, vastly capable and delightfully simple device like the iPad. To see images and text brought together–so quickly!–by the researchers in Kentucky is truly inspiring. The current application is all the proof anyone needs that the work of digitization will serve not only high-end scientific research, but will invite a very wide audience to share in these cultural treasures. As a Classicist, I find this thrilling!”

Few people have the privilege of traveling to the Marciana Library in Venice and studying the actual Iliad folios. But only a month after its March release, the Imaging the Iliad app has already sold more than 800 copies. It is available for free download in the Apple iTunes App store.

'Imaging the Iliad" app allows users to search and bookmark the text, as well as closely examine the high-res folio images.

“The Iliad app brings one of the oldest mediums of communication to one of the newest. This readily accessible preservation of history and culture will hopefully set the standard of how scholarly research should be published,” said Whelchel. Next, the team is “currently working on a 3D viewer that shows off the models we have of each folio. It really brings the ancient book to life when you can spin it around and see the fine creases.”

Puerto Rican Undergraduates Experience Research At UK

Dr. Seales presents to a group of students at the University of Puerto Rico

While the days are still winter gray in Kentucky during February, in Puerto Rico the sun is shining and a soft wind blows off the Atlantic over the capital city of San Juan. On the campus of the University of Puerto Rico near the center of the city, a group of computer science students are meeting with two members of the Vis Center to learn about internship opportunities at the University of Kentucky.

For the past ten years, computer science students from the University of Puerto Rico have spent summers on the campus of the University of Kentucky gaining valuable research skills as well as cross-cultural experience. Vis Center Director and Computer Science Professor, Dr. Brent Seales first visited the island of Puerto Rico in 2000 to begin recruiting students for summer undergraduate research opportunities. Since then about thirty computer science students from the University of Puerto Rico have done research in visualization, networking and other computer science research areas at UK.

In the summer of 2010, the Vis Center launched its VisU program, a summer undergraduate research opportunity for Kentucky and Puerto Rico students. Six students participated in the program completing research projects that ranged from medical imaging and digital humanities applications to iPad app development.

Students at the University of Puerto Rico

This summer, the VisU program is expected to have between six and eight students working on summer research projects. These students will gain both valuable experiences for themselves as well as contributing meaningful work to the research team. Carla Lopez Narváez, one of the University of Puerto Rico students involved in the 2010 VisU program explained her experience this way: “This experience helped me learn how to work together with new people in order to manage and solve the problems we found during the process of our research. We learned how to apply the things we learned to our lives as well as to keep learning new things in order to accomplish our research and become more professional. I would love to do more research in the future!”

Innovative Technology Goes on Stage with UK Opera

The Vis Center’s new innovative high-definition projection technology, originally developed for non-theatrical use, will be used for the first time in a theatrical setting for the UK production, followed by the Atlanta Opera production.

The technology was originally developed at the Vis Center through a partnership with Fort Knox. Its initial application was for the military with the goal of building rapidly deployable, high resolution screens to be used in training or battle. Other potential uses include any environment that needs the mobility and convenience of a display from schools to museums and medical applications.

The projectors are mounted to the scaffolding in a system that also frames the screen.

While front and rear projected backdrops are nothing new to theatre, they can cause problems for the set design and for the performers. Normal front projectors can cast shadows and images onto the performers, and most rear projectors must be placed very far distances behind the screens to create a large enough image of scenery, which can limit the stage space. With the Vis Center’s new rear projection system, only four and a half feet separate the 54 projector units from their attached movable fabric screen units, which are an impressive 24×30′ and 24×15′.

The technology, coined by the Vis Center as SCRIBE (self-contained rapidly integratable background environment), utilizes a software system that blends the projections into one image, which will include still images and video related to the various scenes in the production.

This project grew out of the synergy that is possible through multi-disciplinary research collaboration. The Director of the Vis Center, Dr. Brent Seales came into contact with UK Opera Director, Everett McCorvey, through a chance meeting when they were both speaking at a luncheon hosted by Mrs. Patsy Todd. Both quickly grasped the possibilities of collaboration and over the next year the idea of using this technology as part of the opera production emerged.

Dr. Seales states that this type of multi-disciplinary research is the goal of the Vis Center. “We plan to see more of these type of real applications of our technology continue to take place as we work with other researchers across the University in the future. The possibilities are amazing if you consider what research can do when people step outside of their regular environments to interact with those with a distinctly different background.”

Bill Gregory, lead engineer for the Vis Center, reflected on the value of applying his technical ability to the theatre production, “It’s been fascinating to work with the theatre crew. Being an engineer I am focused on the practical results and never look at the artistic aspect while they didn’t realize the technology that could be used to achieve their artistic ends. We didn’t know what problems existed for them and they didn’t know what to ask for until we collaborated.”

The images will depict real locations in Charleston, SC and the islands off the coast of North Carolina that were taken and edited by the Vis Center team. Actual hurricane footage from The Weather Channel will be used as well. Combining these projected images with a minimal amount of three-dimensional pieces of scenery will create a vibrant and exciting production.

The use of this projection system has already been drawing interest from other opera and theatre companies from around the country.
