Tancred of Bologna
Tancred of Bologna was a most celebrated canonist of the 13th century (who must not be confounded with another Tancred of Corneto; comp. De Savigny, Gesch. d. rom. Rechts im Mittelalter [2d ed.], 5, 135, and p. 115, 116). His preceptors were Azo in Roman and Laurentius in canon law. In 1210 he was himself a teacher (decretorum magister) at Bologna, and entrusted with the management of important affairs by both the pope and the city. He belonged to the Chapter of Bologna, and in 1226 was made archdeacon by Hoiorius III, which position then included among its duties the supervision of promotions in the university. The year of his decease is not known, but it must have been prior to 1236 as the archdeaconate is then found to be in other hands (see Sarti, De Claris Archigynynasii Bononiens. Professoribus, pars 2, fol. 28, 29, 36, 37, 181). His literary remains include a Summa de Matrimonio, written between 1210 and 1213; first published, with numerous interpolations, by Simon Schard (Cologne, 1563), and again, in revised form, by Wunderlich (Göttingen, 1841): — an OrdoJudiciarius (OrdinariusTancredi), written about 1214, and afterwards revised in 1225. 1234, and often by unknown scholars. It was formerly believed that this work originated in about 1227, but the earlier date is now accepted. An edition of the work in its original form was issued by Bergmann (ibid. 1842). Tancred's lectures at Bologna were, among other matters, upon the collections of decretals received into the curriculum of Bologna after the close of Gratian's collection, and resulted in Apparatus, or commentaries, on the first three compilations. He had no part, however, in the preparation of the fifth ancient compilation. In addition to the above, there is extant of Tancred's works a manuscript list of bishoprics throughout the Church, arranged in the order of provinces (De Savigny, ut sup. p. 117, 118).
