LINCOLN, Neb. (AP) — The University of Nebraska-Lincoln says an archaeological team has uncovered a massive Roman mosaic in southern Turkey.

Michael Hoff is an art history professor at UNL and the director of the excavation. He says the 1,600-square-foot work is believed to be the largest mosaic of its type in the region and demonstrates the reach of the Roman Empire in the third and fourth centuries.

Since 2005, Hoff's team has been excavating the remains of the ancient city of Antiochia ad Cragum on the southern Turkish coast.

Excavation has focused on a third-century imperial temple and a shop-lined street. In July, the team began to explore the mosaic, which was part of a Roman bath. The mosaic consists of large squares, each filled with different colored geometric designs and ornamentation.
