Attambelos I was a king of Characene,[1] a Parthian vassal state and important trading port and emporium on the Persian Gulf.
His rule was from 47/46 to 25/24BC.
[2] He is recorded by only four coins dated in the years 10/11, 11/12, 13/14 and 22/23BC.
[3] Like most Characene Coinage, he is depicted himself on the front and Heracles (or Nike) on the reverse.
This ruler is also mentioned by Josephus[4] and there is evidence that his rule was interrupted by a foreign king in the year 18/19.
