In one race Hippomenes (or Milanion) was given three of the golden apples of the Hesperides by the goddess Aphrodite; when he dropped them, Atalanta stopped to pick them up and so lost the race. Their son was Parthenopaeus, who later was one of the Seven who fought against Thebes after the death of King Oedipus. how can i put that in my own words​

Their son Parthenopaeus was later one of the seven who fought aginst the Thebes after the death of king Oedipus.
