Jullio del Carretto (died 13 October 1614) was a Roman Catholic prelate who served as Bishop of Casale Monferrato (1594 - 1614).[1] According to Giuseppe Cappelletti, his first name (as his tombstone indicates) was Tullio, not Jullio.[2]
On 13 July 1594, Jullio del Carretto was appointed Bishop of Casale Monferrato by Pope Clement VIII. On 25 July 1594, he was consecrated bishop by Girolamo Bernerio, Bishop of Ascoli Piceno, with Guillaume de St-Marcel d'Avançon, Archbishop of Embrun, and Marco Antonio Salomone, Bishop of Sora, serving as co-consecrators. He served as Bishop of Casale Monferrato until his death on 13 October 1614. While bishop, he was the principal co-consecrator of Girolamo Palazzuoli, Bishop of Isola (1610); Giambattista Brivio, Bishop of Cremona (1610); and Pietro Bastoni, Bishop of Umbriatico (1611).
