Corvinus [a raven].
Janos Hunyady, Governor of Hungary, is so called from the raven on his shield.
There were two Romans so calledviz. Valerius Maximus Corvinus Messala, and Valerius Messala Corvinus.
Marcus Valerius was so called because, in a single combat with a gigantic Gaul during the Gallic war, a raven flew into the Gauls face and so harassed him that he could neither defend himself nor attack his adversary.
