This bronze mask was probably a votive offering. Masks such as this show up in carvings in Greek and Roman theaters. The mask probably dates to the mid–fourth century B.C.
This mask, along with the four statues, was found in 1959 during building excavations in Piraeus. They were found as a group and although deposited at the same time, they were crafted at different periods. They were probably deposited in the first century B.C.
