Baldachin

Baldachin, also baldaquin, baldachino, or baldacchino, is a tent-like covering or canopy over portals, altars, or thrones, either supported on columns, suspended from the roof, or projecting from the wall. It is a ceremonial canopy made of stone, metal, or fabric. It derives its name from Italian baldacchino, which in turn was derived from Baldacco (Baghdad) from where the original brocade originated. In 16th century the term denoted an embroidered material, woven with silk and gold thread.
