Chashtana is followed by an unbroken chain of successors all of the dynasty of which Chashtana was the founder. As the coins of Chashtana's successors bear dates and as each coin gives the name of the king and of his father they supply a complete chronological list of the Kshatrapa dynasty. [Kshatrapa III. Jayadáman, A.D. 140-143.] Of Chashtana's son and successor Jayadáman the coins are rare. Of three specimens found in Káthiáváda two are of silver and one of copper. Both the silver coins were found in Junágadh [94] but they are doubtful specimens as the legend is not complete. Like Chashtana's coins they have a bust on the obverse and round the bust an incomplete and undecipherable Greek legend. The reverse has the sun and the moon and between them the arched symbol with the zigzag under-line. All round the symbols on the margin within a dotted line is the legend in Baktro-Páli and Devanágarí. Only three letters raño cha ña of the Baktro-Páli legend can be made out. Of the Nágarí legend seven letters Rájno Kshatrapasa Ja can be made out. The remaining four letters Dr. Bhagvánlál read Yadámasa. [95] The copper coin which is very small and square has on the obverse in a circle a standing humped bull looking to the right and fronting an erect trident with an axe. In style the bull is much like the bull on the square hemidrachmæ of Apollodotus (B.C. 110-100). Round the bull within a dotted circle is the legend in Greek. It is unfortunate the legend is incomplete as the remaining letters which are in the Skythian-Greek style are clearer than the letters on any Kshatrapa coin hitherto found. The letters that are preserved are S T R X Y. The reverse has the usual moon and sun and between them the arched symbol without the zigzag under-line. All round within a dotted circle is the Nágarí legend: Rájno Kshatra(pasa) Jayadámasa. Of the king Kshatrapa Jayadáman. Though the name is not given in any of these coins, the fact that Chashtana was Jayadáman's father has been determined from the genealogy in the Gunda inscription of Rudrasimha I. the seventh Kshatrapa, [96] in the Jasdhan inscription of Rudrasena I. the eighth Kshatrapa, [97] and in the Junágadh cave inscription [98] of Rudradáman's son Rudrasimha. All these inscriptions and the coins of his son Rudradáman call Jayadáman Kshatrapa not Mahákshatrapa. This would seem to show either that he was a Kshatrapa or governor of Káthiáváda under his father or that his father's territory and his rank as Mahákshatrapa suffered some reduction. [99] The extreme rarity of his coins suggests that Jayadáman's reign was very short. It is worthy of note that while Zamotika and Chashtana are foreign names, the names of Jayadáman and all his successors with one exception [100] are purely Indian.
