Andreas, Barbatus (so called from his long beard), a celebrated civil and canon lawyer of the 15th century, was born in Sicily, from which place he went to study at Bologna, where he attracted the admiration of every one. His memory is said to have been so retentive that he could remember everything that he read, and could repeat off-hand two hundred arguments proposed to him, with his answers. In law he had so vast a reputation that he was called "the Monarch of the Laws." He was present at the Council of Basle, and died about 1476, leaving many works on the civil and canon law.
