Computer experts at Princeton are helping archaeologists reassemble fragments of an ancient Greek fresco.
A mighty volcanic eruption smothered the Mediterranean island of Thera in the 17th century B.C., preserving a storied trove of cultural and artistic relics from the late Bronze Age.
When it was excavated in modern times, however, much of the trove was like a giant jigsaw puzzle. Greek archaeologists have labored for decades to reconstruct striking frescoes from pieces that still boast their original creamy whites and deep reds.

Now, scientists from Princeton University have introduced them to tools that are expected to speed up the process considerably: a laser scanner to capture three-dimensional images of the precious fresco fragments, and a computer program that figures how they fit together
