Other forms: banderoles
The long, skinny flag or banner that flies from the mast of a ship is called a banderole.
Banderole comes from the Italian word banderuola, or "little banner." That's just what these elongated flags look like, banners with forked ends that flutter off the mast of an old sailing ship or a medieval knight's lance. In architecture, a banderole is also a representation of a streamer or scroll that's engraved with text — this kind of banderole is usually carved from stone.
