Manesus
Manesus was a Parthian prince, who served as military governor and official of Parthian-ruled Mesopotamia and Parapotamia, in addition to being the ruler of the Arabs who lived in those areas. He was also collector of customs. He held these posts during the reign of King Vologases III.
Manesus was the son of the Parthian King Phraates and was active in the aftermath of Trajan's Parthian campaign. He is attested in a Greek parchment from Dura-Europos, dated to 120/1 AD.
