According to some myths Latramys was the son of the wine-god Dionysus and his wife Ariadne, the brother of Thoas, Oenopion, Staphylus, Euanthes, and Tauropolus. He belonged to the leaders of the Helladic tribes which colonized the north-eastern Aegean region.
Latramys' name probably expresses his mission (Greek latreía, "a service," latrís, "dedicate to a service," mystis, "an insider"). Latramys was sent as a leader with some groups of colonists to the northern part of Greece.
