San Domenico Altarpiece

Saint Thomas Aquinas stands on the left in a Dominican habit, holding a quill and an open book while a golden sun radiates from his chest. Beside him, Saint Barnabas is draped in a pink mantle over a blue tunic, looking toward a group of colorful, kneeling angels. The figures stand on a geometrically patterned floor against a serene landscape seen through a classical archway.

Thomas Aquinas represents the Scholastic effort to reconcile Aristotelian logic with Christian theology, providing the structural foundation for the later Neoplatonic syntheses of the Renaissance. The sun on his breast symbolizes the 'light of reason' and divine wisdom, concepts that would be central to the Hermetic and Neoplatonic traditions in Ficino's Florence.
