He was born in Ostia and moved to Bologna, studying law under Jacobus Balduinus and Franciscus Accursius. After working as an advocate in Italy and France, he became a law professor in Bologna in 1228. The commentaries on Roman law attributed to him are valuable as showing the growth of the study of law in Italy, and for their biographical details of the jurists of the 12th and 13th centuries. Odofredus died at Bologna in 1265.
