Similar glass bowls have been recovered from the Antikythera shipwreck, located south of the Peloponnese. This first underwater excavation in Mediterranean waters was undertaken with the assistance of sponge divers in 1900. The ship is thought to have been heading west when it sank sometime in the second quarter of the first century B.C. with a large cargo of terracotta amphorae, glass vessels, and large-scale sculptures of bronze and marble.
