Selemnus

Selemnus in Greek mythology, was a shepherd boy of Achaia. He was found asleep among his herds by the nymph Argyra, and his youth and beauty led her to bestow on him her favor; but the beauty of man is not constant like that of a nymph, who retains her youth and beauty always, and Argyra accordingly forsook her lover when his charms were no longer, fresh and blooming to her eyes. Venus herself endeavored to turn the hard heart of the goddess, but in vain, and Selemnus pined away under the agonies of unrequited love. In her compassion Venus now changed him into a stream, on which she conferred the quality of inducing forgetfulness in the minds of all lovers who should bathe in its waters, so that they might be cured of their passion,
