Aqua regia was first mentioned in the works of Islamic alchemists such as Muhammad ibn Zakariya al-Razi (854-925),[8] and then later mentioned in a work of Pseudo-Geber (ca. 1300).[9] The third of Basil Valentine's keys (ca. 1600) shows a dragon in the foreground and a fox eating a rooster in the background. The rooster symbolizes gold (from its association with sunrise and the sun's association with gold), and the fox represents aqua regia. The repetitive dissolving, heating, and redissolving (the rooster eating the fox eating the rooster) leads to the buildup of chlorine gas in the flask. The gold then crystallizes in the form of gold(III) chloride, whose red crystals were known as dragon's blood. The reaction was not reported again in the chemical literature until 1890. - Wikipedia
