A festoon (from French feston, Italian festone, from a Late Latin festo, originally a festal garland, Latin festum, feast) is a wreath or garland hanging from two points, and in architecture typically a carved ornament depicting conventional arrangement of flowers, foliage or fruit bound together and suspended by ribbons. The motif is sometimes known as a swag when depicting fabric or linen.
