a law-professor in the 13th century, born in Florence. His authority was so great that he was called the Idol of the Lawyers.

(Marianus), a famous critic of the 16th century, born at Aquino in the kingdom of Naples. His Diatreses, printed at Rome in folio, in 1524, on Ovid and Solinus, are a proof of his abilities in that kind of erudition. In his edition of Ammianus Marcellinus there are five books more than in any of the preceding ones; and he affirms he had corrected 3000 errors in that historian. His predominant passion was the searching for and collecting of old manuscripts; yet he made Latin and Italian verses; was complete master of the French, German, and Spanish tongues; and understood optics and music. He purged himself by oath, being charged for being a plagiarist with regard to his Antonius; it being reported, that he had appropriated to himself the labours of Fabricio Varano, bishop of Camerino.
