Written history Cuneiform first appeared about 3200 B.C. and the last texts were published about A.D. 75, scholars say. Most deal with everyday transactions such as taxes and business deals, but others have religious themes and one contains the Epic of Gilgamesh, one of the first known epic poems. As a form of writing, cuneiform is similar to Chinese -- a mixture of picture words and words formed from a syllabic alphabet comprised of hooks and wedges. Documents were usually written on wet clay tablets with long reeds. When the clay dried, the records became permanent. Because it's difficult to ship the tablets and because transporting them, when that is possible, is expensive, most cuneiformists who don't have access to them rely on photographs or drawings sketched by hand. That has serious drawbacks, scholars say. "You don't know how accurate a drawing is, and a photo has to be properly lit to be any good," Snyder said.
Reaching in the dark Furthermore, many cuneiform tablets have never been published in books or magazines, "so it sometimes feels like you're reaching around in the dark," Michalowski said. "You can come up with this wonderful idea based on [published] tablets, but it's frustrating because you can't prove it unless you get a travel grant to go view the actual tablet," he said. Cuneiformists have long dreamed of a way to cut through the tedium of digging through old tablets and writing to curators of museums and private collections with requests to view cuneiform collections. "But technology has never really caught up until now," Snyder said. Rendering objects in three dimensions is much harder than in two, scientists say. Part of the problem is there is relatively little demand for 3-D camera equipment. And most of the existing equipment either can take grainy, large-size photos, which wouldn't have enough detail for cuneiformists or are microscopes that give too much detail, scientists say. "Right now, most of the machines are either too much or not enough," said Donald D. Duncan, an engineer at the Applied Physics Laboratory, who is doing most of the technical designs on machine. Duncan and others have found a Canadian firm that produces a scanner that they believe can be adapted to scan cuneiform. But the machine will have to be significantly modified to handle delicate clay tablets and to scan six-sided objects. The thought of having an easy-to-use 3-D catalog at his fingertips makes sense, Michalowski said, although he acknowledges being a "traditional" person who enjoys the romance of hunting through musty collections to try to prove his theories. "It's kind of like being Indiana Jones, without the beautiful women and explosions," he said. "But I guess we're organizing. I'm sure that in five or 10 years, the Internet will be the only way we study," he added with a sigh.
