bucentaurn.

Etymology: < Italian bucentoro, of uncertain origin; it is commonly supposed that the name was taken from the figurehead of the vessel, representing a creature half man, half ox, which may have been designated by the Greek name *βουκένταυρος , < Greek βοῦς ox n. + κένταυρος centaur (compare ὀνοκένταυρος onocentaur n.); the word is unknown to ancient mythology. The Italian word was sometimes used unchanged.
