Why was king Matthias I called matthias corvinus?

King Matthias I of Hungary was called Matthias Corvinus due to his lineage, as "Corvinus" derives from the Latin Word "corvus," meaning "raven." This nickname references the raven emblem associated with his family, the House of Anjou, and particularly his father, John Hunyadi, who had a raven as his symbol. Matthias Corvinus is also noted for his significant contributions to the arts and education during the Renaissance, establishing a cultural legacy in Hungary.
