Greek Gods and Goddesses are often less directly connected to actual Demons then older lore such as Sumer. This shows the progressive reduction of spiritual knowledge from mainstream to hidden. I think Athena/Minerva is one representation of the attributes of Inanna/Astaroth but Aphrodite/Venus is another one. Greeks have split her attributes. Athena covers her civilization builder, wisdom and war attributes. Aphrodite covers her love and passion ones. There are also cases such as Satan in different stories can be Zeus, Dionysus or even Prometheus (Lucifer the light bringer). In Greek mythology it's usually the case that even when an actual God or Goddess is behind a name in a story the story is about passing some spiritual teachings and not about actually storytelling the life of the Gods.
Athens was named after Athena the Goddess Protector of the City. But the Olympic Games weren't linked to Athens at all. Athens had its own Games : Panathenaic Games
