Crystallization is a concept, developed in 1822 by the French writer Stendhal, which describes the process, or mental metamorphosis, in which the characteristics of a new love are transformed into perceptual diamonds of shimmering beauty.
"In the salt mines, nearing the end of the winter season, the miners will throw a leafless wintry bough into one of the abandoned workings.
Two or three months later, through the effects of the waters saturated with salt which soak the bough and then let it dry as they recede, the miners find it covered with a shining deposit of crystals.
When the sun is shining and the air is perfectly dry the miners of Hallein seize the opportunity of offering these diamond-studded boughs to travellers preparing to go down to the mine."
[2] Along one particular trip into the 500-ft deep Salzburg mines, Stendhal and Madame Gherardi were introduced to an intelligent Bavarian officer who thereafter joined their company.
From this observation Stendhal formulated his concept of mental "crystallization" and thus set forth to explain it to Madame Gherardi, who was curiously unaware of the officer's enhanced infatuation for her.
