Festoon

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.

[3][4] In modern English the verb forms, especially "festooned with", are often used very loosely or figuratively to mean having any type of fancy decoration or covering.

Its origin is probably due to the representation in stone of the garlands of natural flowers, etc., which were hung up over an entrance doorway on fête days, or suspended around an altar.

[2][4] The design was largely employed both by the Ancient Greeks and Romans and formed the principal decoration of altars, friezes and panels.

[4] The ends of the ribbons are sometimes formed into bows or twisted curves; when in addition a group of foliage or flowers is suspended, it is called a drop or margent.
