What do the ancient texts say ?

Ovid, (a Roman poet of the Ist century BC), tells the story of Diana and Actaeon ; this is how he describes Diana bathing:
"There was a valley there called Gargaphie, dense with pine trees and sharp cypresses, sacred to Diana of the high-girded tunic (...) A spring of bright clear water murmured into a widening pool, enclosed by grassy banks. Here the woodland goddess, weary from the chase, would bathe her virgin limbs in the crystal liquid. Having reached the place, she gives her spear, quiver and unstrung bow to one of the nymphs, her weapon-bearer. Another takes her robe over her arm, while two unfasten the sandals on her feet."
(Metamorphoses, III, 156-168)
