epithet Corvinus was coined by Matthias' biographer, the Italian Antonio Bonfini, who claimed that the Hunyadi family descended from Marcus Valerius Corvinus. The Hungarian legend relates that when a raven carried off the ring King Matthias had removed from his finger he chased the bird down and slew him retrieving the ring, and in commemoration of this event, he took the raven as a symbol for his signet sign. Really, this coat of arms was used by Matthias's ancestors far earlier than he did. His own father John Hunyadi, voivode of Transylvania and regent of Hungary, is known as Ioannes Corvinus in Medieval Latin. In addition the Silesian Annals (other version of this legend) tell that was not the king himself who shot the raven but a Polish soldier, who was rewarded with the Korwin coat of arms. Matthias Corvinus was also ruler of the Duchy of Głogów, and as titular Bohemian king (and as conqueror most of territory of the Bohemian Crown), suzerain of all Silesian duchies. Actually, Matthias Corvinus raised the Black Army which is recognized as the first standing continental European fighting force not under conscription and with regular pay since the Roman Empire. The soldiers of the Black Army were mainly Bohemian mercenaries (former Hussites), but Poles, Germans, Hungarians and adventurers from all over Europe joined as well. Sometimes officers were rewarded with lands and ennoblement. This may be a more realistic origin of the Korwin coat of arms, in Silesia at first (part of the Bohemian kingdom), and all around the Polish–Lithuanian commonwealth later. In time, baroque authors related the old Slepowron coat of arms with then more "fashionable" name Korwin. Korwin coat of arms can be found on the tombstone of the Chancellor of Cracow Academy Łukasz Noskowski (also Łukasz of Noskowa; †1532), buried in St. Mary's Basilica, Kraków. Image of a raven also appears on the city seal of Głogów from March 17, 1490. A raven sitting on a branch was the emblem of the Corvinus/Korwin family, which ruled in the Duchy of Głogów in the second half of the 15th century and gave their emblem to the city. Blazon Gules, on a cut off tree stump laid sideways proper, between two upper and two lower knots stands a left facing raven sable, in its beak, a ring or with the diamond facing down. In the crest, above a crowned helmet, there are
