    A New Look at Old Buildings
    By Victor Wishna

    >>From the nave floor of the Amiens Cathedral in northern France,
    Stephen Murray's gaze sweeps upward to the vault high above. "This
    really is my favorite view inside the cathedral," he says, pointing
    out the diagonal and transverse ribs that crisscross the ceiling of
    this Gothic structure completed in 1269, a mere forty-nine years
    after construction began. "It was really quite quick," he says.

    Click. Now he is in Turkey, soaring over the rooftops and zipping
    through the streets of historic Istanbul. "Ooh, look at that!" Murray
    exclaims, pointing to the intricate stonework in the courtyard of the
    Sultan Ahmet Mosque, built in 1616. "I've not seen that before."

    Click. A building looks familiar . . . the Parthenon? "This is the
    treasury," he says. "Let's go into the main hall." Suddenly he is
    standing before the statue of Athena, her golden veneer shimmering in
    the light rays reflecting off the pool at her feet.

    Of course, he's not really in the Parthenon; it's a reproduction in
    Nashville, Tennessee. And he's not exactly in Nashville, either-nor
    was he in Amiens or Istanbul, but in Room 605 of Schermerhorn Hall,
    Murray's comfortable but architecturally less impressive office at
    Columbia University.

    Murray, a professor in the Department of Art History and Archaeology
    and founder of its Visual Media Center, conducts his whirlwind tour
    across continents entirely on the small screen of his PowerBook. Each
    tap on the touch pad reveals another lifelike panorama offering
    360-degree views in every direction.

    These "nodes"--image modules rendered in QuickTime Virtual Reality
    (QTVR)--are all part of the Visual Media Center's new History of
    Architecture web project supported by NEH (www.mcah.columbia.edu/ha).
    When the site officially launches this spring it will contain more
    than six hundred such nodes encompassing dozens of buildings, from
    temples in Greece to the great churches of Europe and shrines of
    Yemen and Iran, to Frank Lloyd Wright's Fallingwater house in
    Pennsylvania. Even in its nascent stages, the site is revolutionizing
    the teaching of architecture and changing the way professors and
    their students see and think about buildings that have stood for
    centuries.

    "There are a lot of new issues being raised-and that's part of what
    technology does," says Robert Carlucci, who took over as director of
    the Visual Media Center in 1999 and has overseen the rapid growth of
    the History of Architecture project. "It's a lot more information.
    The psychology of the classroom is really changing."

    "What the media has done is not just unleash all these wonderful
    images, but it allows you to ask questions that otherwise wouldn't
    have occurred to you," Murray says, such as "'How does it feel? What
    do you hear?'"

    The new technology, says Murray, allows for the dispersal of old
    assumptions and for discussions that go beyond structural design. For
    example, by enabling students to peer up into the corners, to see
    where the vaulting shafts had been reinforced with chains and the
    flying buttresses refortified and replaced, the node reveals that
    Amiens was not the sturdy feat of engineering that stood the test of
    time.

    "There's this old-fashioned view that Gothic architecture was driven
    bit by bit, that it was so technical," Murray says, when in fact, it
    was the result of a series of creative leaps. "It was the ideological
    that drove the thing, not the empirical." He acknowledges that George
    Lucas of Star Wars fame makes for a good analogy to a Gothic planner:
    "Both projected a dream where the technology didn't yet exist, but
    that dream had an amazing effect."

    The lesson, he says, is that "scientific revolutions often come with
    a paradigm shift," that is, through grand visions rather than
    incremental advancements. In the case of Gothic architecture, such
    plans brought together great theologians, planners, and masons, who
    otherwise wouldn't interact.

    An up-close look at the pilier columns and vault ribs reveals that
    the magnificent concave and convex shapes of the cathedral were
    created through the relatively low-tech methods of printing and
    stamping, similar to how Jell-o retains the shape of a mold. For this
    reason, Murray says, cathedrals were viewed as repositories of
    memory; in medieval times, stamping-to stamp an image on the
    brain-was the metaphor for memory. "Today, of course, that metaphor
    is the computer," he says.

    The new technology has already been incorporated into the
    undergraduate core curriculum at Columbia, one of the few
    universities to include structural design in its required courses.
    "The idea is that any educated person should have something to say
    about a piece of architecture," Murray says. Some of the nodes have
    been used to teach at colleges and private high schools on an
    experimental basis, and the goal of the site is to make them
    accessible to teachers everywhere.

    "More and more schools have electronic classrooms," Carlucci says.
    "That's especially true at community colleges and state schools-more
    than in the Ivy League in a lot of ways."

    While the project has blossomed in the last few years, its seeds were
    planted nearly a decade ago, at the dawn of userfriendly
    virtual-reality technology. Murray had been interested in "animating
    architecture" ever since, as an undergraduate at Oxford more than
    thirty years ago, he was part of an expedition to film an
    eleventh-century cathedral in Armenia.

    By the time he arrived at Columbia to teach medieval architecture in
    1986, he had grown frustrated with the visual resources available,
    especially because most great cathedrals stood on the other side of
    the ocean. "There's only so many times I could take my students to
    St. John the Divine, which is a beautiful building, and we're lucky
    to have it," he says of the nineteenth-century church that rises a
    few blocks from Columbia's campus. "Otherwise, I had to rely on
    pictures. I can't bring Amiens Cathedral into my classroom."

    With the help of colleagues in the architecture school and a grant
    from NEH, he created a three-part film series entitled The Amiens
    Project to recreate the geometric conception and construction of the
    cathedral. The experience gave Murray the idea to animate the
    medieval segment of Columbia's core curriculum. This initiative led
    to the founding of the Visual Media Center, which has since been
    folded into the Department of Art History and Archaeology.

    Student response to the medieval component was so positive that it
    seemed shortsighted to stop there. "That's when the idea arose that
    we could create a general resource for the history of world
    architecture," says James Conlon, a staff research associate who has
    worked on the site since 1999, collecting much of the imagery from
    Turkey and Yemen. "Medieval, Renaissance, Baroque, Byzantine,
    Islamic, even modern--we kept expanding."

    Today, the site contains all those categories, and a few more. In
    many cases, the nodes are paired with interactive floor plans of the
    building, enabling users to click on a "hot spot" to see the
    perspective from that point. Some views are from dramatic
    locations-thirty feet up on the triforium, on the roof, even inside
    the massive spire-where normal tourists never go.

    There is almost no text on the site, which is by design. Carlucci
    says the idea is to make the site as user-friendly as possible, a
    place to explore and discover rather than read. "The kind of
    intellectual excitement one gets from a building-it dies on the page
    with all this boring prose," Murray says. "The whole idea that we
    don't have to kill the work of art in order to study it is a fabulous
    thing."

    Most of the photography from Amiens and other medieval
    sites--particularly the precarious shots from the parapets--is the
    work of Andrew Tallon, a doctoral student in early Gothic
    architecture.

    As Tallon explains it, the technology is, conceptually at least,
    rather simple. A highresolution digital camera is attached to a
    special tripod and carefully calibrated to take several dozen photos
    around a central point. These photos are then stitched together using
    virtual-reality software. It's a little like the tourist who takes
    several overlapping pictures, and then, after developing them, cuts
    and pastes them together to create his own 360-degree panorama. Only
    the site's panoramic nodes are perfectly seamless spheres and can be
    downloaded from the Internet.

    On the site, most nodes are rendered at low resolution so they can be
    accessed with low-speed connections. For classroom use, the nodes can
    be rendered at high resolution for a teaching demonstration that's
    light years beyond blurry slides. "I was able to zoom into
    individual, sculptural details and move around without ever having to
    change photographs," says Tallon, who taught an introductory art
    history class at Columbia last year. "This is an extraordinary
    advance in terms of teaching medieval sculpture. The node is able to
    preserve an entire view of a space in a way that no other
    photographic technology can."

    Beyond the classroom, the most beneficial aspect of the site may be
    in how it lets anyone explore the great buildings of the world at
    their own pace, in their own homes, without the interference of tour
    guides "charging ahead with their brightly colored umbrellas," Murray
    says.

    Murray says he had two objectives when he began the project: first,
    that it should provide students access to the same resources their
    professors use, and second, that it should bring together faculty
    from different institutions to form new collaborative relationships.

    The first mission has been a success. Rather than sending students
    home with only their notes and memories of the slides they saw in
    class, "now I can say, 'Go study Amiens Cathedral,' and they can.
    It's changed me as a teacher," Murray says. "I'm a much better
    teacher than I was just a few years ago."

    While Murray and Carlucci have recruited colleagues at MIT, Bryn
    Mawr, Mount Holyoke, and other institutions to contribute to the
    site--Murray envisions a single great online course called Medieval
    Architecture with each expert adding a segment-getting them to
    actually use it has proven more challenging.

    For some, the technology--and what it offers-may be intimidating.
    "Say you're a faculty member who's been teaching the same image since
    the beginning of time because that's the only one that had been
    published," Carlucci explains. "And maybe that image was a view down
    the center of the building. Well, now suddenly students can look up
    and see something going on in the ceiling. Before you know it, you've
    got questions being thrown at you that you were never prepared for."

    But Murray believes teachers will learn to welcome those
    uncertainties. "I was amazed at how my students, on their own,
    grasped the subtleties," Tallon says from Paris, where he is
    continuing to shoot for the site while completing his thesis on
    flying buttresses. "They managed to understand spatial aspects of
    Gothic architecture that would have taken an actual trip to the
    building to communicate otherwise."

    And even then, says Murray, they may not get quite as good a look.
    "The only way to get that perspective is to lie on your back in the
    middle of the floor," he says, studying his favorite view of Amiens.
    "In reality, that's not something you're likely to do."

    Columbia University received $575,000 from NEH to create the History
    of Architecture web project. Stephen Murray received an NEH
    fellowship and grant of $138,000 to create a multimedia education
    tool on Amiens Cathedral. Murray has conducted four NEH summer
    seminars for college teachers on the Gothic in the Ile-de-France.
