Greek, Thessaly, about 350 B.C, Marble
The Greek hero Achilles, identifiable by his shield and helmet, rides with his mother Thetis in a chariot on this fragmentary relief. The chariot slowly converges on a procession of worshippers, who are dressed as travelers, wearing cloaks and wide-brimmed hats. Only seven of these waiting men remain on the broken relief, but originally there must have been about ten. In Greek religion, many heroes were worshipped and had religious cults associated with them. It was believed that they could intercede on the behalf of mortals. Achilles was certainly worshipped as a hero, and some scholars believe that in certain places, he may even have been worshipped as a god. In this relief, the group of worshippers brings three rams to sacrifice to Achilles. Scholars believe it was made in Thessaly, where, according to Greek mythology, Achilles was born and educated. The relief takes the usual form of a votive monument that was set up as an offering in a religious sanctuary. The dedicators are named in the partially legible inscription at the bottom of the relief, which gives the names of Lakrates and Gephes and refers to the religious association of the Achilleides, who claim to be descendants of Achilles.
