In the marginalia El Greco inscribed in his copy of Daniele Barbaro's translation of Vitruvius' "De Architectura", he refuted Vitruvius' attachment to archaeological remains, canonical proportions, perspective and mathematics. He also saw Vitruvius's manner of distorting proportions in order to compensate for distance from the eye as responsible for creating monstrous forms. El Greco was averse to the very idea of rules in architecture; he believed above all in the freedom of invention and defended novelty, variety, and complexity. These ideas were, however, far too extreme for the architectural circles of his era and had no immediate resonance.
