Homer is full of beautiful women and strong men. Paris and Helen. Achilles and Hector. Odysseus. Even the godesses are beautiful. White-armed Hera and Hera of the flashing eyes. Who wants to read about ugly people?
Mythology is all about super heroes.
There is a school of thought that the NT is influenced by Paul's classical education. They say Plato saw physical reality as just a shadow of the spiritual but I am not so sure. Plato's Academy included a gymnasium for athletes to train, usually naked. Plato valued physical fitness and does not seem to me to be sexually repressed. Some scholars think he was gay. Where the sexual repression in the NT and the lack of description of physical beauty comes from is quite a puzzle. Certainly much of it does seem to be from Paul.
