The term is lamassu. Lamassu is an Assyrian defensive divinity, frequently delineated as having a human's head, a body of a bull or a lion, and flying creature's wings. In a few compositions, it is depicted to speak to a female god.
Expansive lamassu figures up to about five meters high are dynamite show-stoppers in Assyrian mold, where they are the biggest figures known to have been made.
