Salmacis (fountain)

Salmacis was a fountain, located near the mausoleum at Halicarnassus. In classical times, it had:

"the slanderous repute, for what reason I do not know, of making effeminate all who drink from it. It seems that the effeminacy of man is laid to the charge of the air or of the water; yet it is not these, but rather riches and wanton living, that are the cause of effeminacy. " —Strabo [http://www.perseus.tufts.edu/cgi-bin/ptext?doc=Perseus%3Atext%3A1999.01.0198&layout=&loc=14.2.16 "Geography XIV.2.16’']

This was illustrated by Hellenic sculptors, who produced several works depicting a person of dual-gender. The power of the spring was rejected by other Romans, such as the architect Vitruvius

"there is a mistaken idea that this spring infects those who drink of it... it cannot be that the water makes men effeminate" —Vitruvius ’’On Architecture’’ 2. 11-12

Ovid creates or recounts the myth of how the fountain came to be so in the story of the nymph Salmacis (after whom the fountain is, in this account, named), her attempted rape of Hermaphroditus, and his resultant change into an intersexual being.
