In 2010 the “(crypto)signature” in stylized letters “RAFFAEL SANT PXT” and the date 1501 in Roman numerals “MDI” were discovered inserted in the arabesque decoration of the border of Saint Catherine’s mantle.
The presence of Raphael in Città di Castello in those years is proven by the historical sources and consolidated by studies and therefore the date shown on the “small tablet or small panel painting” is perfectly consistent with the biographical events of the Artist.
Moreover, Raphael’s practice of affixing his signature and cryptosignature on paintings was his typical habit during his youthful period and it was also a practice of many other artists before becoming famous.
