Petasos

A petasos or petasus (Greek:πέτασος) is a sun hat of Thessalian origin worn by the ancient Greeks, often in combination with the chlamys cape. It was usually made of wool felt, leather or straw, with a broad, floppy brim. It was worn primarily by farmers and travellers, and was considered characteristic of rural people. As a winged hat, it became the symbol of Hermes, the Greek mythological messenger god (Roman equivalent Mercury).
