Why are there so many nudes in European works of art?

The ancient Greek gods are also a great source of nudity in western art. This is because the image of ancient Greek gods is basically certain. For example, Hermes must be wearing flying shoes, holding a wand and walking like a fly; Athena must hold a spear and wear a helmet; Zeus and Poseidon must grow beards, one with Thor's hammer and the other with trident; The girl who wins must have fluttering clothes and flying wings; Apollo must be a beautiful teenager, Aphrodite (Venus in ancient Roman mythology, hereinafter referred to as Venus) must be a beautiful girl and so on. ? Therefore, anyone who wants to paint the ancient Greek gods must have these characteristics and wear ancient Greek robes. The following picture shows the images of three victorious girls in Athens Archaeological Museum, almost identical.
