Moon Toad

In Chinese mythology, the ch'an , a three-legged toad, lives in the moon and is supposed to swallow it during an eclipse. The toad is very long-lived and grows horns at the age of three thousand years. It was originally a woman named Ch'ang O, who stole the drug of Immortality and fled to the moon to escape her husband's wrath. The moon is often referred to as ch'an , as in the poem.
