Infula, Infulae (pl)

The ribbons attached to a mitre. The term originates in Rome from a band or fillet, made of locks of wool knotted at intervals, worn by priests and Vestal virgins, and used to decorate altars, victims, etc. Label was also sometimes anciently used to describe this term.

Infula was also a cap tank or a deep round cap with strings to tie under the chin used by the freed Roman slaves. It later became one of the symbols of the French revolution,  generally depicted high, of a pyramidal form, differently turned up as illustrated.
