Then Zeus’s daughter Helen thought of something else.
Into the mixing-bowl from which they drank their wine
she slipped a drug, heart’s-ease, dissolving anger,
magic to make us all forget our pains…
No one who drank it deeply, mulled in wine,
could let a tear roll down his cheeks that day,
not even if his mother should die, his father die,
not even if right before his eyes some enemy brought down
a brother or darling son with a sharp bronze blade.

– Homer

The Odyssey, Book 4, lines 243-251. Helen slips a drug into the wine to make Menelaus and the visiting Telemachus and Pisistratus forget their sorrow and pain. They have been lamenting Odysseus’ delayed return home from Troy.
