There was a city in ancient Achaea, also named Argyra, that was the site of a spring.
According to legend, the nymph Argyra was in love with a shepherd named Selemnus whom she visited frequently.
[1] But when he aged and his youthful beauty vanished, she forsook him.
When the boy died of grief, the goddess Aphrodite out of pity changed him into a river, the Selemnos.
There was a popular belief in Achaia that a forsaken lover who bathes in this river will forget their pain.
