Marpessa (Μάρπησσα) means "snatcher" in Greek. The princess of Aetolia who was given the choice between marrying Apollo or the mortal Idas — she chose the mortal, **explaining that Apollo would abandon her in old age while a mortal would grow old with her**. One of the few Greek figures to choose mortal love over divine.
Marpessa Dawn (1934-2008) was the African-American actress who starred in Black Orpheus (1959).
Marpessa reduces to seven — the number of Greek choice.
