author and saint. While he enjoyed studying at Collegio Clementino, his attention turned toward civil and canon law. Soon after, in 1694 at the age of nineteen, he received the degree of Doctor of Sacred Theology and Doctor Utriusque Juris (both ecclesiastical and civil law). Ecclesiastical career Lambertini became an assistant to Msgr. Alessandro Caprara, the Auditor of the Rota. After the election of Pope Clement XI in November 1700, he was made a consistorial advocate in 1701. Shortly after, he was created a Consultor of the Supreme Sacred Congregation of the Roman and Universal Inquisition, and then in 1708 Promoter of the Faith. As Promoter of the Faith, he achieved two major successes. The first was the canonization of Pope Pius V. The second was the composition of his treatise on the process of the beatification and canonization of saints. In 1712, Lambertini was named Canon Theologus of the Chapter of the Vatican Basilica and member of the Sacred Congregation of Rites; in 1713 he was named monsignor; and in 1718 secretary of the Sacred Congregation of the Council. On 12 June 1724, only two weeks after his election, Pope Benedict XIII appointed Lambertini titular bishop of Theodosia. Lambertini was consecrated a bishop in Rome, in the Pauline Chapel of the Vatican Palace, on 16 July 1724, by Pope Benedict XIII. The co-consecrators were Giovanni Francesco Nicolai, titular Archbishop of Myra (Vicar of the Vatican Basilica), and Nicola Maria Lercari, titular Archbishop of Nazianzus (Papal Maestro di Camera). In 1725, he served as the Canonist at the Roman Synod of Pope Benedict XIII. In 1718, the Istituto delle scienze ed Arti Liberali in Bologna had begun construction of a chapel for everyday convenience dedicated to the Annunication of the Virgin Mary. In 1725, Bishop Prospero Lambertini of Theodosia, who was working in the Roman Curia but was mindful of his origins, ordered the chapel to be painted. He handed over the work to Carlo Salarolo, who had the walls of the chapel adorned. Lambertini also ordered and paid for the painting above the main altar, an image of the Virgin being greeted by the angel, the work of Marcantonio Franceschini. He was made Bishop of Ancona on 27 January 1727, and was permitted to retain the title of Archbishop, as well as all the offices which he had already been granted. He was also allowed to continue as Abbot
