CASTELLESI, ADRIANO (146o?-1521), Italian cardinal and writer, known also as CORNETO from his birthplace, was sent by Innocent VIII. to reconcile James III. of Scotland with his subjects. While in England he was appointed by Henry VII., to the see of Hereford, and in to the diocese of Bath and Wells, but he never resided in either. Returning to Rome, he became secretary to Alexander VI. and was made cardinal (May 31, 1503) . Soon after the election of Leo X. he was implicated in the conspiracy of Cardinal Petrucci against the pope. He confessed his guilt, fled from Rome and was deposed from the cardinalate. As early as 1504 he had presented his palace (now the Palazzo Giraud-Torlonia) to Henry VII. as a residence for the English ambassador to the Holy See; and on his flight Henry VIII., who had quarrelled with him, gave it to Cardinal Campeggio. Of Adrian's subsequent history nothing is known. As a writer, he was one of the first to restore Latin to its pristine purity ; and among his works are De Vera Philosophia ex quatuor doctoribus ecclesiae (Bologna, 1507), De Sermone Latino (Basle, 1513) and a poem, De Venatione (Venice, See B. Gebhardt, Adrian von Corneto (Breslau, i886).
