Hecatomnus or Hekatomnos (Greek: Ἑκάτoμνως) was the early 4th-century BC ruler of Caria. He was nominally merely the governor (Satrap) for the Persian king Artaxerxes II (404–358 BC), but ruled as a de facto autonomous monarch.


Hecatomnus was appointed by the Persian king to command the naval forces destined to take part in the war against Evagoras I of Cyprus[1]; but the operations of the war were at that time allowed to linger, and it appears Hecatomnus shared the spirit of disaffection towards Persia common at that time. When hostilities were resumed at length and in earnest against Evagoras, he not only took no part in support of the Persian monarchy, but secretly supplied Evagoras with sums of money to raise mercenary troops.[2] No notice, however, seems to have been taken of this act of treachery, a circumstance for which the disorganised state of the Persian monarchy will fully account, and Hecatomnus continued to hold possession of Caria in a state of virtual independence until his death. The date of this cannot be ascertained, but we learn from Isocrates[3] that he was still ruling in 380 BCE.

He left three sons, Mausolus, Idrieus and Pixodarus, and two daughters, Artemisia and Ada, who were married to their brothers Mausolus and Idrieus[4], all five of whom in turn succeeded him in the sovereignty.

Hecatomnus was a native of Mylasa, and made that city his capital and the seat of his government: hence we find on his coins the figure of Zeus Labrandenos, represented as walking and carrying a labrys over his shoulder, from the celebrated temple of that name near Mylasa.[5]

In August 2010, law enforcement officials arresting individuals believed to be digging for antiquities discovered what Turkish officials believe to be the tomb of Hecatomnus.[6] A marble sarcophagus and numerous frescoes were discovered in the tomb, although officials also believed many relics had already been taken from the tomb and sold on the black market.[6]
