A banderole (French: [bɑ̃dʁɔl] ⓘ, "little banner") is a comparatively small but long flag, historically used by knights and on ships, and as a heraldic device for representing bishops.
Bannerol, in its main uses is the same as banderole, and is the term especially applied to banners about a yard square carried at the funerals of great men and placed over the tomb.
Banderole (a wooden stick having one pointed end covered with metallic shoe) is used in conventional military survey.
[3] The term is also used in art and architecture for a speech scroll or streamer, representing a roll of parchment carried by or surrounding a figure or object, for bearing an inscription, mainly during the medieval and Renaissance periods.
They may also be used for the words of angels, especially Gabriel's greeting to Mary in Annunciation scenes.
