the son of Sanatruces, whom Dio Cassius (77.12) calls king of the Parthians. [ARSACES XXIX.] Vaillant thinks that he was the king seized upon by Caracalla. On the other hand, the Armenian historians tell us that Wagharsh, in Greek Vologeses or Valarsases, the son of Dikran (Tigranes), reigned over Armenia, or part of Armenia, from A. D. 178 to 198, and that he perished in a battle against the Khazars, near Derbent, in 198.
It is of course impossible that he should have been seized by Caracalla, who sueceeded his father Septimius Severus in 211. Nor do the Armenians mention any king of that name who was a contemporary either of Septimius Severus or Caracalla. (Moses Choren. 2.65-68.)
