Temenus was a son of Aristomachus and a descendant of Heracles. After the conquest of the Pelopennesus he was allocated Argos as the result of a drawing of lots, and became its king. His name means 'portion of land' (temenos), from temno, 'to cut', 'draw a line', and this could be an indication of the land that he won.

Another Temenus was a son of Pelasgus who is said to have reared Hera in the Arcadian city of Stymphalus. There he built three shrines to celebrate three different aspects of the goddess (as Maiden, as Bride, and as Widow), and for him temenos is also appropriate since apart from meaning 'portion of land' it also meant 'piece of land sacred to a god', 'precinct'.
