Phrygian cap, soft felt or wool conical headdress fitting closely around the head and characterized by a pointed crown that curls forward. It originated in the ancient country of Phrygia in Asia Minor and is represented in ancient Greek art as the type of headdress worn by Orientals. In Rome the Phrygian cap was worn by emancipated slaves as a symbol of their freedom. During the 11th and 12th centuries, it was again extensively used.
The Phrygian cap once more became the emblem of liberty in the 18th century during the French Revolution, when it was adopted by the Revolutionaries as “the red cap of liberty.” It continues to be associated with the national allegorical figure of Liberté.
