The Chalkeia festival (also spelled Chalceia), the festival of Bronze-workers, was a religious festival devoted to the goddess Athena. It was celebrated on the last day of Pyanepsion (October or November in the Attic calendar). The festival celebrated Athena and Hephaestus, in honor of both gods as patron deities of Athens, and as deities of handicrafts. Each year, preparations were begun for a specialized peplos (a robed garment worn by Greek women), which was made to be offered to the goddess at another festival, the Panathenaea.
