ANDREA, Gioanni, a celebrated canonist, born (says Tiraboschi) at Bologna, towards the end of the thirteenth century, of parents who were natives of Mugello near Florence. His father kept a grammar school at Bologna; but eight years after the birth of his son, having obtained the living of Sta Maria de' Galluzzi, he took orders, and rebuilt that church at his own expense. Andrea studied civil law under Martino Sulimans and Ricardo Malombra, and canon law under Guido da Baijo. The words Sub cuius umbra quiesco, et doctor sedeo, in the beginning of his Decretals, are supposed to have reference, not as commonly asserted to pecuniary assistance from Baijo, but to the professorship which through his interest Andrea obtained at Bologna, whether he removed from Padua where he had previously kept a school. In 1328 he was introduced by Cardinal Bertrand to Pope John XXII. at Avignon. Four years afterwards, when popular fury obliged the cardinal to leave Bologna, Andrea accompanied him to Florence, where he cannot have remained long, for in 1337 he was sent from Bologna on an embassy to Venice and Padua. He was a member of the general council of Bologna in 1340; and if he ever was professor at Pisa, as commonly supposed, it was probably after that period, as no mention of him occurs again until 1348, when it is recorded that he died at Bologna of the plague, and was buried in the church of the Dominicans. The aspersions on the character of this eminent man, must be ascribed to the malevolence of those who envied his great reputation: the titles of rabbis doctorum, lux, normaque morum, bestowed on him, prove the public estimation of his learning, and his morals; and R. Volterrano and Filippo Villani testify to his vigils, fasting, and mortification. The story that his accomplished daughter Novella occasionally supplied her father's place in the lecture room, concealed by a curtain lest her beauty should distract the attention of the pupils, appears to rest on very slender foundation; and equally improbable is the common opinion that he named the decretals of Gregory "Novella" in honour of her, that title having probably been given after the example of Justinian in his supplement to the Corpus Juris. Andrea wrote the following works:—Gloss upon the Sixth Book of the Decretals; Glosses upon the Clementines; Commentary on the Rules of Sextus. His additions to the Speculum of Durando, are taken literally from the Consilia of Oldradus; as also the book De Sponsalibus et Matrimonio from J. Anguiscola.
