|Heliokles II Dikaios ("The Just")|
Portrait of Heliokles II
Heliocles II Dikaios (Greek: Ἡλιοκλῆς Β΄ ὁ Δίκαιος; epithet means "the Righteous") is thought to have been one of the later Indo-Greek kings and a relative of the Bactrian king Heliocles I. Bopearachchi and R. C. Senior seem to agree that he ruled ca 95–80 BCE (see Overstrikes).
Heliocles II seems to have been engaged in a series of wars with Strato I in Gandhara and Punjab; the two share several mintmarks and Heliocles II overstruck many of his coins. During this period, a number of kings fought for hegemony in the Indo-Greek territories. Some of them were likely supported by nomad Saka rulers such as Maues.
Heliocles II used a reverse of standing Zeus, who was a common deity among the later Indo-Greek kings. J. Jakobsson sees Heliocles as the son of the important king Antialcidas Nikephoros (whose type was sitting Zeus) and perhaps the grandson of Heliocles I.
He goes on to suggest that Heliocles was the older brother of the king Archebius Nikephoros Dikaios, who seems to have succeeded Heliocles II in Gandhara (perhaps after his death from disease; Heliocles I looks emaciated on his later portraits). Archebius uses a very similar reverse and combines the epithets of Heliocles II and Antialcidas; in addition, their coin portraits are similar, with hooked noses and fierce expressions.
R.C. Senior has instead suggested a connection with Demetrius III, who used a similar reverse of standing Zeus.
Coins of Heliocles II
Heliocles II issued Indian silver with portrait (diademed, helmeted or spear-throwing) / standing Zeus and bronzes with bearded diademed portrait (Heliocles or Zeus) / elephant.
It is uncertain whether he struck Attic coins. A number of posthumous coins for Heliocles I have been found in Bactria; possibly some of these may have been struck by Heliocles II, though there are no similar monograms.
The existence of numerous overstrikes helps locate the reign of Heliokles II in relation to other Indo-Greek kings. Heliokles overstruck coins of Agathokleia, Strato I, and Hermaeus. Conversely, Amyntas overstruck coins of Heliokles II. These overstrikes would suggest that Heliokles II reigned around 95–85 BCE, and was a contemporary of Amyntas and Hermaios
