I want to know the answer to the following question:
Artaxian coins called some Armenian kings what?
All the background I'm provided with is that "Cleopatra, the wife of Tigranes the Great, invited Greeks such as the rhetor Amphicrates and the historian Metrodorus of Scepsis to the Armenian court, and - according to Plutarch - when the Roman general Lucullus seized the Armenian capital Tigranocerta, he found a troupe of Greek actors who had arrived to perform plays for Tigranes.". Is that enough to answer the question?
Answer: no
