Raffaello, trinità (1505-1508) e santi del perugino (1521), santi 04 giovanni evangelista

The saint is shown with long white hair and a flowing beard, wearing a bright yellow tunic draped with a heavy blue mantle. He holds a thick, closed book with red edges between both hands. A simple circular gold halo floats above his head against a pale, multi-toned background.

Saint John is central to the Western esoteric tradition as the author of the Gospel of John, which introduced the Neoplatonic concept of the 'Logos' into Christian theology. This philosophical bridge was essential for Renaissance thinkers who sought to reconcile ancient Greek philosophy with sacred scripture.
