Vitellius, Erasmus a Polish bishop, was born about 1470, at Cracow, of obscure parentage. He studied in the university of that place at the expense of the family of Ciolek de Vitellio, whose name he assumed. In 1491 he became doctor at the university, and in 1504 was nominated by prince Alexander as bishop of Plock. He visited Rome twice to present the salutations of his sovereign to the pope. In 1518 he was sent by Sigismund to the Dict of Augsburg to solicit aid against the Turks, as well as on other diplomatic services. He died in 1522. See Biographie Universelle s.v.
