Some of the nominations were excellent, such as Lorenzo Campeggio, Giambattista Pallavicini, Adrian of Utrecht, Cajetan, Cristoforo Numai and Egidio Canisio.
His works were collected by Cardinal Cajetan, and were published in four volumes at Rome (1606-1615), and then at Paris in 1642, at Venice in 1743, and there are other editions.
But he resigned his benefices, and, in conjunction with Cajetan, founded the order of the Theatines (1524) with the object of promoting personal piety and of combating heresy by preaching.
His proper name was Tommaso 1 de Vio, but he adopted that of Cajetan from his birthplace.
Cajetan was employed in several other negotiations and transactions, being as able in business as in letters.
