D’Aubusson to deal with a man who was fully his equal in the art, and whose extensive system of espial had rendered him well acquainted with the real motives by which the Ottoman sultan was actuated. Perceiving that a short truce would give time for such reinforcements to arrive as were still lingering on the way, he yielded a ready assent to the proposals of Demetrius, merely taking objection to the question of tribute, as to which he averred that he was not authorized to treat without special reference to the Pope.

One of these was Antonio Meligala, a Rhodian, who, having dissipated his patri-
