Room of the Signatureby Raphael (Raffaello Sanzio) (1483-1520)Raphael's Rooms The Room of the Segnatura contains Raphael's most famous frescoes. The room takes its name from the highest court of the Holy See; the 'Segnatura Gratiae et Iustitiae'; which was presided over by the pontiff and used to meet in this room around the middle of the 16th century. Originally the room was used by Julius II (pontiff from 1503 to 1513) as a library and private office. The iconographic programme of the frescoes; which were painted between 1508 and 1511; is related to this function. It was certainly established by a theologian and meant to represent the three greatest categories of the human spirit: Truth; Good and Beauty.
