The Greek name of the personification of hope left in Pandora’s jar is Elpis.
Elpis is a figure in Greek mythology associated with hope and expectation. In Hesiod’s Works and Days, the evils escape from Pandora’s container, but Elpis remains inside after Pandora replaces the lid. The detail gives the myth its famous contrast between the spread of suffering and the preservation of hope.
Elpis is not one of the major Olympian gods. She is instead an abstract personification, comparable to other Greek figures who represent conditions or forces in human life. Roman tradition later associated hope with the goddess Spes.
A common mistake is to treat “hope” as merely a modern moral added to the story. Hesiod names a mythological figure, although translations usually render her name by the ordinary English word rather than preserving “Elpis.”
