The acts of the consistories convoked by Popes Pius V and Gregory XIII during the period from May 7, 1570 through Feb. 2, 1575. The author of the minutes, Cardinal Santori, was one of the most eminent minds of the clergy in the 16th century and a close advisor to Pope Pius V. He was always a participant and frequently an initiator of the meetings which took place as often as once a week under Gregory.
Santori's record was published under the title Diario concistoriale, edited by Tacchi Venturi, within his series Studi e documenti di storia e diritto, Rome, 1902-1904. In the present ms. copy, there are some records of consistories left out, at the end of the reign of Pope Pius V. See Pastor, Gesch. der Päpste, vols. VIII and IX.
