From its beginning the Santa Sabina "studium" played the special role of frequently providing papal theologians from among its members. Since its institution in 1218 the office of Master of the Sacred Palace has always been entrusted to a Friar of the Order of Preachers. In 1218 Saint Dominic was appointed as the first Master of the Sacred Palace by Pope Honorius III. In 1246 Pope Innocent IV appointed Annibaldo degli Annibaldi (c. 1220 – 1272) third Master of the Sacred Palace after Saint Dominic and Bartolomeo di Breganze. Annibaldi had completed his initial studies at the Santa Sabina "studium conventuale" and was later sent to the "studium generale" at Paris. Aquinas dedicated to Annibaldi the "Catena aurea", which he wrote during his regency at the Santa Sabina "studium" beginning in 1265.
