Agostino Oreggi (1577 – 12 July 1635) was a Catholic theologian and cardinal. As personal theologian of Pope Urban VIII, he was involved in the Galileo affair. Life Agostino Oreggi was born in 1577 in the little town of Santa Sofia, in the Grand Duchy of Tuscany near the borders with Romagna. His parents were from Bironico in the canton of Ticino in Switzerland. He moved to Rome in 1594 for studying. With the support of Cardinal Roberto Bellarmino he graduated in philosophy and theology in the Collegio Romano held by the Jesuits, and he earned also a doctorate in utroque iure. He became the "personal theologian" of Card Bellarmino. In 1605, already a priest, Oreggi moved to Faenza where he taught and entered in contact with Maffeo Barberini, Cardinal legate of the near Bologna from 1611 to 1614. He remained in service of Maffeo Barberini as his almoner and theologian. A turning point in the life of Agostino Oreggi was the elevation of Maffeo Barberini to the papacy as Pope Urban VIII in August 1623. In January 1624 he became Consultor (judge) of the Holy Office and member of the Congregation of the Council. He worked with his colleagues of Congregation of Propaganda Fide in publishing a rebuttal of Islamic doctrine in 1625 and in 1630 to permit the Jesuits to evangelize Japan. In 1633 he was part of a committee that studied a reshape of the dioceses in Irland, due to the persecutions suffered by the Catholics there. Oreggi, together with Melchior Inchofer and Zaccaria Pasqualigo, studied the Dialogue Concerning the Two Chief World Systems of Galileo Galilei, and certified that, with the publishing of such book, Galileo did violate the order received in 1616 not to hold, teach, or defend that the sun stands still at the center of the world and the earth moves. Oreggi was created cardinal priest with the title of S. Sisto in the consistory of 28 November 1633, and on the same day he was appointed Archbishop of Benevento. He died in Benevento on 12 July 1635 and was buried in that cathedral. Works Among Oreggi's works are: De Deo uno tractatus primo (1629); De individuo sacratissimae Trinitatis mysterio; De angelis; De opere sex dierum, a study on the first five days of creation supporting the idea that the knowledge of the man about the physical reality is uncertain; De sacrosancto incarnationis
