Philip Melanchthon
Philip Melanchthon (born Philipp Schwartzerdt; 16 February 1497 – 19 April 1560) was a German Lutheran reformer, collaborator with Martin Luther, the first systematic theologian of the Protestant Reformation, intellectual leader of the Lutheran Reformation, and an influential designer of educational systems. He stands next to Luther and John Calvin as a reformer, theologian, and molder of Protestantism. After Luther himself, he is the primary founder of Lutheranism.
Antun Vrančić
Antun Vrančić was in touch with German philosopher, theologian and reformer Philipp Melanchthon (1497–1560); and with Nikola Šubić Zrinski (1508–1566), Croatian ban, poet, statesman and soldier. In "Viaggio in Dalmazia" (1774), Alberto Fortis noted that Vrančić's descendants still kept a letter to Vrančić from Dutch philosopher, humanist and writer Erasmus (1465–1536), but no other evidence of correspondence between the two exists today, and modern scholars find it unlikely.
