At the time Praxiteles was working, Greek sculpture had certain conventions. Men were depicted heroically nude, dicks out. Meanwhile, sculptures of women were always clothed.
Praxiteles decided to mix things up. Working on a sculpture for the Temple of Aphrodite at Knidos, Praxiteles made the decision to depict Aphrodite as nude, emerging from a bath.

The Aphrodite of Knidos sculpture was an immediate sensation. It became a tourist attraction - people would flock to see the naked Aphrodite. Over time, numerous copies were made of Praxiteles's famous sculpture as everyone wanted a nude Aphrodite in their temple, too.
