ANDREAS (John), a celebrated canonist in the 14th century, was born at Mugello, near Florence; and was professor of canon-law at Padua, Pisa, and afterwards at Bologna. It is said that he macerated his body with fasting; and lay upon the bare ground every night for 20 years together, covered only with the skin of a bear. Andreas had a beautiful daughter, named Novella, whom he loved extremely: and he is said to have instructed her so well in all parts of learning, that when he was engaged in any affair which hindered him from reading lectures to his scholars, he sent his daughter in his room; and left her beauty should prevent the attention of the hearers, she had a little curtain drawn before her. To perpetuate the memory of this daughter, he intitled his commentary upon the Decretals of Gregory IX. the Novella. He married her to John Calderinus, a learned canonist. The first work of Andreas was his Glossa upon the sixth Book of the Decretals, which he wrote when he was very young. He wrote also Glosses upon the Clementines; and a Commentary in regulas Sexti, which he intitled Mercuriales, because he either engaged in it on Wednesdays (diebus Mercurii) or because he inserted his Wednesdays disputes in it. He enlarged the Speculum of Durant, in the year 1347. This is all which Mr Bayle mentions of his writings, tho' he wrote many more. Andreas died of the plague at Bologna, in 1348, after he had been a professor 45 years; and was buried in the church of the Dominicans. Many eulogiums have been bestowed upon him. He has been called archidoxor decretorum: In his epitaph, Rabbi doctorum; lux, censor, normaque morum; "Rabbi of the doctors, the light, censor, and rule of manners." And it is said, that pope Boniface called him lumen mundi, "the light of the world."
