Mysia was a semi-legendary kingdom which was located in the north-western corner of Anatolia, on the coast of the Sea of Marmara. Theoretically, it could have existed outside Greek myth and history as the Arzawan sub-kingdom of Masa. To its immediate west was the Troad (of which Mysia was part) and Wilusa, while the newly-arrived Phrygians were settling on its south-eastern border. Maeonia, to the south, was separated from it by Mount Temnus. While those borders are difficult to pin down, apparently for periods of its existence it also extended over areas of western and southern Anatolia, before being submerged within Phrygia. The northern section of the kingdom was known as Mysia Minor or Hellespontica, while the southern section was called Major or Pergamene, and it is this that eventually became the heart of the later kingdom of Pergamum. Information on kings is from Herodotus and the dates have been estimated to bring them into line with those established for the Trojan War
A minor episode in the Trojan War cycle in Greek mythology has the Greek fleet land at Mysia, mistaking it for Troy. Akhilleus wounds their king, Telephos, after he slays a Greek; Telephos later pleads with Akhilleus to heal the wound. In the Iliad, Homer represents the Mysians as allies of Troy, with the Mysian forces led by Ennomus (a prophet) and Chromius, sons of Arsinous. Homeric Mysia appears to have been much smaller in extent than historical Mysia, and did not extend north to the Hellespont or the Propontis. Homer does not mention any cities or landmarks in Mysia, and it is not clear exactly where Homeric Mysia was situated, although it was probably located somewhere between the Troad (to the northwest of Mysia) and Lydia/Maeonia (to its south).
It is also mentioned in Jason and the Argonauts. It is one of the early stops in the quest for the fleece. It is where Herakles goes off to repair his oar and leaves the Argonauts and returns to his Labors
