A petasos () or petasus (Latin) is a broad brimmed hat of Thessalian origin worn by ancient Greeks, Thracians and Etruscans, often in combination with the chlamys cape. It was made of wool felt, leather, straw or animal skin. Women's versions had a high crown while those for men featured a lower crown. It was worn primarily by farmers, travellers and hunters, and was considered characteristic of rural people. As a winged hat, it became the symbol of Hermes, the Greek mythological messenger god.
