The School of Athens

A solitary man in a purple tunic sits on stone steps, resting his head on his hand while leaning against a large block of marble to write. He is depicted in a moment of deep contemplation, physically separated from the communal dialogue of the other philosophers in the scene. His heavy boots and rugged appearance reflect the persona of the sculptor Michelangelo, whom Raphael added to the composition as a tribute.

Heraclitus represents the pre-Socratic doctrine of eternal change and the Logos, while his melancholic posture reflects Renaissance Neoplatonic ideas regarding the 'divine madness' and temperament of the creative genius. This connection between scholarly melancholy and intellectual insight was a major theme in the works of Marsilio Ficino and the Florentine Academy.
