Cupid, n. The so-called god of love. This bastard creation of a barbarous fancy was no doubt inflicted upon mythology for the sins of its deities. Of all unbeautiful and inappropriate conceptions this is the most reasonless and offensive. The notion of symbolizing sexual love by a semisexless babe, and comparing the pains of passion to the wounds of an arrow -- of introducing this pudgy homunculus into art grossly to materialize the subtle spirit and suggestion of the work -- this is eminently worthy of the age that, giving it birth, laid it on the doorstep of prosperity.
