Colonna, Giacomo (2)

Colonna, Giacomo (2)

an Italian prelate, lived in the early part of the 14th century. Pope John XXII appointed him bishop of Lombez in return for the courage he manifested in publishing at Rome the excommunication pronounced against Louis of Bavaria. As a protector of Petrarch, Colonna contributed much to bring about the coronation of that poet at Rome in 1341, and Petrarch addressed to him a canzone. See Hoefer, Nouv. Biog. Generale, s.v.
