MARTINO da FANO. - Jurist, born at Fano around 1190 into the noble Del Cassero family, also mentioned by Dante (Inf., XXVIII, 77; Purg., V, 73). He studied law at Bologna, where he was a pupil of Azzone, and by 1229 was already a professor. He taught at Arezzo, where he was rector of the University, and then soon became a professor at Modena. He also held important offices: he was podestà of a city in Romagna and twice of Genova (1260 and 1262). Shortly thereafter he entered the Order of S. Domenico and died at Fano around 1272. He was buried in the church of S. Domenico.
He was highly esteemed among the Bolognese students of law, and his works are frequently cited, although they have for the most part been lost. The most important are: De iure emphytentico, a treatise often printed, but under the name of Guido da Suzzara; De modo studendi, a short but learned treatise collected by Alberigo, of which one manuscript remains; De homagiis, which was almost entirely reproduced in the Speculum of Durante; a Formularium super contractibus et libellis (ed. Wahrmund 1907); an Ordo iudiciarius (ibid. 1907); De imploratione brachii saecularis, of which a new manuscript has recently been edited (v. BIBLICA).
