Cino da Pistoia
He was born in Pistoia, Tuscany. His full name was Guittoncino dei Sinibaldi or, latinised, Cinus de Sighibuldis. His father was a noble man from the House of Sinibaldi. He received his doctorate from the University of Bologna, where he studied under Dinus de Rossonis, and taught law at the universities of Siena, Florence, Perugia, and Naples. In 1334, he was elected Gonfaloniere of Pistoia, but did not take up the office.
Cino's most important legal work was Lectura in codicem (1312–1314), a commentary on the Justinian Code which blended pure Roman law with contemporary statutes and customary and canon law, thereby initiating Italian common law. He wrote some 200 lyric poems notable for purity of language and harmony of rhythms, most of them dedicated to a woman named Selvaggia. Dante, a friend of his, in De vulgari eloquentia, praised his poetry.
