Elpis was the Greek equivalent of the Roman Spes, the goddess of hope. She was traditionally defined as "the last goddess" (Spes, ultima dea), meaning that hope is the last resource available to men. Elpis personified hope for good harvests, and for children, and was invoked at births, marriages, and other important times.
