This coin, 30.16, which Sellwood assigned to an Unknown King (II), as Shore 134 maps to Orodes I, in Sear maps to Gotares I, Mitchiner to Mithradates II, Wroth to Artabanus II, and Gardner, Plate II #9, to Phraates II. So clearly there has been some discussion over the years about who this type belongs to. Besides the question of “who” is on this coin, I was pulled in by the portrait on this Parthian drachm, the unusually misshapen flan, and toning. Parthia, Arsakes XVI, AR Drachm, Rhagae mint Obv: short-bearded bust left wearing diadem, hair covering ear; single-pellet-ended torque; circular border of pellets Rev: beardless archer wearing bashlyk and cloak seated right on throne; empty cloak sleeve ends in pellet reaching well below seat level, holding bow in right hand; no border; five-line Greek inscription = ΒΑΣΙΛΕΩΣ ΜΕΓΑΛΟΥ ΑΡΣΑΚΟΥ ΘΕΟΠΑΤΟΡΟΣ ΕΥΕΡΓΕΤΟΥ == “Great King Arsakes, Son of Deified Father, (and) Just” Ref: Sellwood 30.16 Assar assigns this coin to Arsakes XVI in The Sunrise Collection, Numismatic Art of Persia, Bradley Nelson Editor This was the Arsakes who challenged Orodes I in 78/77 BC and overthrew him in Bablylon ~75 BC and to whom King Mithridates VI of Pontus, together with Tigranes I, wrote to for aid against the Romans circa 68-69BC during the Third Mithridatic War: King Mithridates to King Arsaces (XVI): Greetings. All those who in the time of their prosperity are asked to form an offensive alliance ought to consider, first, whether it is possible for them to keep peace at that time; and secondly, whether what is asked of them is wholly right and safe, honorable or dishonorable. If it were possible for you to enjoy lasting peace, if no treacherous foes were near your borders, if to crush the Roman power would not bring you glorious fame, I should not venture to sue for your alliance, and it would be vain for me to hope to unite my misfortunes with your prosperity. - Sallust Histories 4.69 Other facets of the story can be found in these sources: - Plutarch Lucullus 30.1-2 - Dio Roman History 36.1.1 - Appian Mithidatic Wars 13.87 This encounter between Rome and Parthia comes about 25 years after the first challenging meeting between Mithradates II's ambassador and Sulla on the banks of the Euphrates. Arsakes XVI may have been the son of Mithradates II hence the line on this coin “ΘΕΟΠΑΤΟΡΟΣ” son of deified father. Assar, in Sunrise, also writes that Arsakes XVI may have struck coins 68-61 BC while campaigning to oust Phraates III. The Third Mithridatic War (73–63 BC) ends with Roman domination and the story of Mithridates' antitoxin causing troubles in his suicide attempt. An overview of that can be found here. As always, comments, corrections, and additions to any of the above are appreciated. Post your misshapen flans, coins of 73–63 BC, or anything also you find interesting or entertaining.
