Cover art for Cupid De Locke lyrics by Smashing Pumpkins, The

The title "Cupid de Locke" is a reference to Matthew Locke (1621-1677), an English baroque composer, who wrote the score to "Cupid and Death" in 1653, a kind of ballet in which Cupid fires arrows to make people fall in love, and Death fires arrows which bring about a person's demise. They get their arrows mixed up and hilarity ensues. Two men are fighting a duel and instead of killing each other, they fall in love and start dancing! Sadly, young lovers are killed. A man falls in love with a monkey. Eventually, order is restored.

The style of music in the SP song is similar to the baroque. Matthew Locke was the mentor of Henry Purcell who is much more famous.

I suppose the title roughly means "Locke's Cupid".
