What does it mean to shoot a poisoned arrow

… into s.o.'s heart?

Who has coined the expression? Shakespeare?

Does anyone know a dictionary where this notion is mentioned?

Thank you!

Hi!

The origins seem to be Greek mythology

„In another well-known story, a centaur named Nessus tried to rape Deianira, the wife of Hercules. Hercules caught him and shot the centaur with a poisoned arrow. As he lay dying, Nessus urged Deianira to save some of the blood from his wound.“
