Antonio Bonfini was the first chronicler to have made a passing remark of an alternative story of John Hunyadi's parentage, soon stating that it was just a "tasteless tale" fabricated by Hunyadi's opponent, Ulrich II, Count of Celje. According to this anecdote, John was actually not Voyk's child, but King Sigismund's illegitimate son. The story became especially popular during the reign of John Hunyadi's son, Matthias Corvinus who erected a statue for King Sigismund in Buda. The 16th-century chronicler Gáspár Heltai repeated and further developed the tale, but modern scholarsfor instance, Cartledge, and Kubinyiregard it as an unverifiable gossip. Hunyadi's popularity among the peoples of the Balkan Peninsula give rise to further legends of his royal parentage.
