In Greek mythology, Moria was a Naiad nymph dwelling by the river Hermus; she makes an appearance in Nonnus' Dionysiaca, in an episode that is as follows.
Moria's brother Tylus accidentally touched a serpent, which then attacked Tylus, coiled round his body and suffocated him; Tylus was not his first victim. Moria only could helplessly watch her brother die, but then Damasen, a Giant son of Gaia, arrived on the spot; Moria implored him to help and he killed the serpent, hitting it with the trunk of a tree he tore out of the ground. Then a female serpent, the slain monster's mate, appeared and used a magical herb, referred to as "Zeus' flower", to bring the dead serpent back to life. Moria then used the same herb to revive her brother.
It has been speculated that the myth of Moria, Tylus and Damasen may be rooted in Lydian mythology.
