What does Raphael's School of Athens mean?

Toward the end of 1508, the young painter and architect Raphael was summoned by Pope Julius II to Rome to complete an artwork. Though he arrived as an artist of little distinction, his finished piece would become one of the most significant artworks of the Italian Renaissance. Raphael’s School of Athens is one of several frescoes decorating a suite in the Vatican’s papal apartments, where Julius lived and worked. Today this suite is known as the Stanze di Raffaello, or Raphael's Rooms, and the room in this suite where the School of Athens is painted is called the Stanza della Segnatura. The painting depicts a lineage of secular knowledge, highlighting philosophers, artists, and mathematicians from throughout history. The scholars’ identities are often debated: Is that Michelangelo’s likeness standing in for the philosopher Heraclitus? Is this Alexander the Great or Alcibiades? Is that Raphael himself, peeking out from under a beret? The interlocking groups of figures, whoever they are, guide viewers toward the center of the piece. There, an easily identified Plato and Aristotle stand as if in debate. Small details represent the two philosophers’ intellectual differences. Plato, whose work engaged with spiritual ideas like truth, beauty, and justice, points skyward. Aristotle, who was more concerned with earthly reality, gestures toward the ground. Both hold copies of their own books in their hands. By focusing attention on Plato and Aristotle, the School of Athens illustrates a central question of Western philosophy: whether meaning is found in the spiritual realm or the physical world. And viewed in context with the other frescoes in Raphael’s Rooms—pieces created for a papal residence, to celebrate religious glory—it’s not too unconventional to believe that the painting picks a side.
