MARTINO da FANO. - Jurist, born in Fano around 1190 from the noble Del Cassero family, also mentioned by Dante (Inf., XXVIII, 77; Purg., V, 73). He studied law in Bologna, where he was a pupil of Azzone, and by 1229 he was already a professor. He taught in Arezzo, where he served as rector of the university, and soon after moved to Modena as a professor. He also held important positions: he was podestà of a city in Romagna and twice of Genoa (1260 and 1262). Shortly thereafter, he entered the Order of St. Dominic and died in Fano around 1272. He was buried in the church of San Domenico.
He was highly esteemed among the Bolognese jurists, and his works, though largely lost, are frequently cited. The most important are: *De iure emphyteutico*, a treatise often printed but under the name of Guido da Suzzara; *De modo studendi*, a brief but learned treatise collected by Alberigo, of which a manuscript survives; *De homagis*, which is almost entirely reproduced in the *Speculum* of Durante; a *Formularium super contractibus et libelli* (ed. Wahrmund 1907); an *Ordo iudiciarius* (ibid. 1907); *De imploratione brachii saecularis*, of which a new manuscript has recently been published (v. BIBLICA).
