Rezakhani 2017, p. 32, From the numismatic point of view, the early Indo-Parthians before the rise of Gondophares were little-known authorities who produced coins initially in the style of the Parthians (i.e. Arsacids) and then the Indo-Scythian kings such as Maues.16 They might have been Parthian, or possibly ‘Saka’, satraps of Sakistan/Sistan appointed by the Arsacid ruler. This can be observed from the coins of Cheiroukes, who calls himself a ‘satrap’ of the Marsakes region, matching the eastern provinces of the Arsacid Empire, and later Sistan proper. The coinage of a series of authorities whose names are given as Tanlis, Tanlis Mardates, and probably a queen named Rangodeme are quite likely to be the last series issued by these ‘satraps’ before the establishment of the dynasty of Gondophares in Sistan and Arachosia. The early rulers of Sakistan/Sistan can thus be characterised as Arsacid governors, possibly of Saka origin, who are appointed following the defeat of the Sakas in the region by Mithridates II.
