BBB Etymology - Put the cart before the horse
The first reference to this phrase in English comes in George Puttenham's The arte of English poesie, 1589:
"We call it in English prouerbe, the cart before the horse, the Greeks call it Histeron proteron, we name it the Preposterous."He was probably referring back to, or possibly translating directly from, a work by Cicero (106 BC - 43 BC) - On Friendship:
"We put the cart before the horse, and shut the stable door when the steed is stolen, in defiance of the old proverb."
