Usually worn as an outer garment in the ancient Mediterranean world, it developed in different styles, colours, and materials. The Greek chlamys (worn only by men) was a short mantle draped around the upper shoulders, pinned on the right shoulder with a brooch. It left the right arm free and was often used by travellers and military men. The Greek himation, draped in various ways, was a larger Greek mantle.Some Christian religious vestments, such as the cope and the pallium, probably developed from the mantle.in biology, soft covering, formed from the body wall, of brachiopods and mollusks; also, the fleshy outer covering, sometimes strengthened by calcified plates, of barnacles.The mantle of mollusks and brachiopods secretes the shell in species that possess shells. It also forms a mantle cavity between itself and the body. The brachiopod mantle has a dorsal and a ventral lobe covered with small papillae (nipple-like projections) that penetrate into the shell. The molluscan mantle has a left and a right lobe and, as in bivalves, may be joined at the edge to form siphons for directing water into and out of the mantle cavity.
