Aug. 9 (UPI) -- Italian divers have found a 2,100-year-old shipwreck off the coast of Sicily, with hundreds of ancient clay jars known as amphorae, likely used to carry wine.

The shipwreck was found off the coast of Mazara del Vallo, at the northeast corner of Sicily.

Italian Culture Minister Alessandro Giuli called it, "one of the most important underwater archaeological discoveries of recent years."

Underwater fisherman and free diver Giacomo De Mola said he was out on the water with his friend Igor Bisulli. Their boat sonar showed something that looked like a rock, and on a hunch, he dove to investigate. When he came back up, he told Bisulli, "You can't imagine what's down there."
