Anne Boyer, in A Handbook of Disappointed Fate (p. 86, footnote): "Stendhal, in his book on love, describes the process of love's crystallization: leave a lover with his thoughts for 24 hours, and this is what will happen. At the salt mines of Salzburg, they throw a leafless wintry bow into one of the abandoned workings. Two or three months later, they haul it out, covered with a shining deposit of crystals. The smallest twig, no bigger than a tom-tits' claw, is studded with a galaxy of scintillating diamonds. The original branch is no longer recognizable."
