What a creature he was! Never have I felt such a horse between my knees. His great haunches gathered under him with every stride, and he shot forward ever faster and faster, stretched like a greyhound, while the windbeat in my face and whistled past my ears.

Gargoyles were the complement to saints; Leonardo's caricatures were complementary to his untiring search for ideal beauty. And gargoyles were the expression of all the passions, the animal forces, the Caliban gruntings and groanings which are left in human nature when the divine has been poured away. Leonardo was less concerned than his Gothic predecessors with the ethereal parts of our nature, and so his caricatures, in their expression of passionate energy, merge imperceptibly into the heroic.
