late 14c., from Old French conope "bed-curtain" (Modern French canapé), from Medieval Latin canopeum, dissimilated from Latin conopeum, from Greek konopeion "Egyptian couch with mosquito curtains," from konops "mosquito, gnat," of unknown origin. The same word (canape) in French, Spanish, and Portuguese now means "sofa, couch." Italian canape is a French loan word.
c.1600, from canopy (n.). Related: Canopied; canopying.
in architecture, a projecting hood or cover suspended over an altar, statue, or niche. It originally symbolized a divine and royal presence and was probably derived from the cosmic audience tent of the Achaemenian kings of Persia. In the Middle Ages it became a symbol of the divine presence in churches. During the 14th and 15th centuries, tombs, statues, and niches were overhung with richly decorated tabernacle work in stone, and these were reflected in delicate spiral wooden canopies over fonts.
