“But when a great artist or a great writer lays hold upon either sort of ugliness he transfigures it instantaneously. With a touch from the magic ring he metamorphoses it into beauty. His Is a sort of fairy alchemy. His Is a sort of fairy alchemy.
When Velasquez, paints Sebastian, King Philip's dwarf, he gives him such an appealing look that we read the poor creature's secret and see the tragedy it involved — a man forced to get his living by discarding his human dignity, and becoming a toy, a living joke. The more poignant his martyrdom, within that misshapen body, the more beautiful the artist's work.
When Millet paints a poor rustic leaning upon a hoe, a wretch broken by fatigue, scorched by the sun, degraded as a beast of the field, he has only to add an expression of resignation in order to make this hideous nightmare a magnificent symbol of humanity.
When Shakespeare gives us Tago or Richard III, and when Racine gives us Néron and Narcisse, moral ugliness, interpreted by minds so clear, so penetrating, becomes a marvelous theme of beauty.”

Rodin on realism, 1910
