Beth war, for whan that Fortune list to glose,
Thanne wayteth she her man to overthrowe
By swich a wey as he wolde leest suppose.
– Geoffrey Chaucer
The Canterbury Tales, The Monk’s Tale. The Monk says that when Fortune waits to deceive she waits to overthrow her man in such a way that is least expected. He speaks this after recounting the death of Hercules.
