Ware the sonne in his ascencioun.
– Geoffrey Chaucer
The Canterbury Tales, The Nun’s Priest’s Tale. Pertelote warns Chauntecleer to beware the sun when it is high in the sky – part of her advice to stop his bad dreams, which she says are the result of indigestion and gas from overeating. Her warning turns out to be as prophetic as his dream, when terror later strikes Chauntecleer as the sun is high.
