Anotations

Scope note:

Wide-brimmed, low-crowned sun hats thought to be Thessalian origin, worn by ancient Greeks, Etruscans, and Romans; considered traveling hats. The style was revived during the early Medieval period. These hats are believed to have been made of wool felt, leather, or straw, with a floppy brim. The god Hermes/Mercury was originally portrayed with wide-brimmed traveling hats; when his depictions were changed to winged hats, these were also often called "petasuses" even if they were close-fitting caps.
