Comaetho of Cilicia

In Greek mythology, Comaetho (Κομαιθώ) is a queen of Cilicia who fell in love with the local river-god Cydnus. The goddess Aphrodite then transformed her into a spring, and the queen was acquatically joined with her beloved for the rest of time.

Family
The fifth-century poet Nonnus describes Comaetho as a daughter of Cydnus, though elsewhere he simply describes her as his lover. Like Cydnus, now known as the Berdan River, Comaetho was from Cilicia, a region located in southern Asia Minor. Comaetho is both described as a mortal woman and a Naiad nymph.

Mythology
The maid Comaetho ruled over the Cilicians. As she approached marriage age, the girl fell in love with the river-god Cydnus and pined for him until the goddess Aphrodite turned her into a spring, presumably in order to unite the two. Thereafter Comaetho was glad to join him in wedlock and mingle her newly-formed waters with those of Cydnus.

Background
The earliest attestment for this story comes from a Parthenius fragment, preserved by Eustathius of Thessalonica who is in turn quoted by Stephanus of Byzantium; in this case the story would be the earliest example of a full metamorphosis into a body of sweet water.

The myth might have arisen as a geographical, aetiological narrative in order to describe a spring near Glaphyrae, a town in Cilicia, and thus could be traced back to Parthenius's own Metamorphoses work. Some doubts have been cast over this assertment, as it is most likely that that work was written in hexameters.

The story of Comaetho has been compared to that of the river-god Alpheus and the nymph Arethusa, owing to their shared theme of contrast of the water and the fire of love. It also bears similarities with another fragmentary text by Parthenius regarding the story of Byblis; both myths feature maidens sufffering from their incestuous passions, if Cydnus is taken to be Comaetho's father.
