As a philologist, he authored a handbook on the Latin language titled Elegantiae linguae Latinae; interest in that language led him to author another a treatise that argued a certain Roman ruler must have hid his true nature from his relatives and friends if Pope Sylvester I was really given authority over the entirety of the Western Roman Empire. For 10 points, name this Renaissance philosopher who demonstrated that the Donation of Constantine was a forgery.
