How does Hamlet's Father die?

Question: How does Hamlet's Father die?

Answer: Claudius, Hamlet's uncle, assassinated Hamlet's father by pouring the "juice of cursed hebenon" (1.5.63) in his ear while he slept in his orchard. Hebenon is a folk name for Henbane, the expressed juice of the fresh plant, Hyoscyamus niger. Other folk names for Henbane include Black Nightshade, Cassilago, Devil’s Eye, and Jupiter’s Bean. The death of Hamlet's father was inspired by a real event in 1538, when the Duke of Urbino was killed by a poisoned lotion rubbed into his ears by his barber.
