Marcus Valerius Corvus, a Roman general, born about 371 B. C., died about 271. In 349, being tribune under L. Camillus in his campaign against the Gauls, he accepted the challenge of a gigantic barbarian to single combat, and killed his antagonist, as the story goes, with the assistance of a raven, which perched upon Valerius's helmet, and as often as he advanced upon his foe flew at the Gaul's face. A general battle ensued, in which the Romans were completely victorious. From this circumstance Valerius is said to have derived his surname of Corvus. He was made consul in 348 and five times subsequently. In 343 he gained two brilliant victories over the Samnites at Mount Gaurus and at Suessula. In 342 he was appointed dictator in consequence of a mutiny in the army, which he quelled by his personal popularity. He was dictator again in 301, when he defeated the Marsi and Etruscans. The last 28 years of his life were passed in retirement. He held curule dignities 21 times, and repeatedly enjoyed the honors of a triumph.
