The article discusses the initial stage in the biography of Andreas Dudith (1533-1589), i. e. his studies, originally in Wroclaw and then in Italy (mainly under Aldo Manuzio jr.), travels across Europe as a member of the entourage of Cardinal Reginald Pole, which ended within a parting of ways, a religious crisis, and a distinct sympathy for anti-Trinitarianism. These inclinations were disclosed only among friends from Padua. Ultimately, Dudith did not renounce an ecclesiastical career in his native Hungary, which both his family and the imperial court urged him to pursue. When Dudith finally left Padua in 1559 he was already celebrated among European humanists thanks to his classical erudition, whose sample he presented in a translation of 'De Thucididis historia iudicium by Dionysios of Halicarnassus' (1560) and the enthusiastic opinions of Aldo Manuzio.
