The School of Athens was painted by the 27 year old Raphael (Raffaelo) Sanzio (or Santi) for Pope Julius II (1503-1513). In 1508 the young native of Urbino had been recommended to Julius II by Donato Bramante, the pope’s architect, and also a native of Urbino. So enthusiastic was the pope when he saw the fresco that Raphael received the commission to paint the entire papal suite. The Stanza della Segnatura was to be Julius’ library, Bibiotheca Iulia, which would house a small collection of books intended for his personal use. The Fresco of Raphael’s School of Athens is a masterpiece of Art. However we do not know all details of the persons who are depicted. Giorgio Vasari and others have suggested nearly all Greek philosophers and ancient scientists can be found here. Unfortunately Raphael did not leave any personal notes on this work but some of the persons can be identified. The work shows that Raphael was an educated person, had some knowledge of Greek philosophy and science. We can consider “The School of Athens” as a “ visualization of knowledge”.
