Geromino, cardinal and archbishop of Brindisi, was born in 1480, and distinguished himself by his fiery zeal against the Reformation. Being sent into Germany as the pope's nuncio in 1519, he acted as occasion served, in the character both of ambassador and doctor, and opposed Luther in the diet of Worms with bitter vehemence. His violent conduct alienated him from Erasmus, who had been his early friend. He published several works, and died at Rome in 1542.

Geromino, grand-nephew of the former, a jurist, antiquarian, and poet, was born at Motta, near Friuli, in 1574. He was long employed as secretary to Cardinal Ottavio Bandini, and afterwards to Cardinal Barberini, in whose service he died, at Rome, in 1629. He was one of the first members of the Academy of Humourists, wrote a learned treatise in Italian on the device of the society, and displayed his genius on many different subjects. Barberini gave him a magnificent funeral at the Academy of Humourists.
