Paphlagonia and Cappadocia Acquired
Lastly, in Asia Minor the king turned his eyes towards the interior of Paphlagonia--the coast had for long belonged to the Pontic empire-- and towards Cappadocia.(8)
8. The chronology of the following events can only be determined approximately. Mithradates Eupator seems to have practically entered on the government somewhere about 640; Sulla's intervention took place in 662 (Liv. Ep. 70) with which accords the calculation assigning to the Mithradatic wars a period of thirty years (662-691) (Plin. H. N. vii. 26, 97). In the interval fell the quarrels as to the Paphlagonian and Cappadocian succession, with which the bribery attempted by Mithradates in Rome (Diod. 631) apparently in the first tribunate of Saturninus in 651 (IV. VI. Saturninus) was probably connected. Marius, who left Rome in 665 and did not remain long in the east, found Mithradates already in Cappadocia and negotiated with him regarding his aggressions (Cic. ad Brut. i. 5; Plut. Mar. 31); Ariarathes VI had consequently been by that time put to death.
The former was claimed on the part of Pontus as having been bequeathed by the testament of the last of the Pylaemenids to king Mithradates Euergetes: against this, however, legitimate or illegitimate pretenders and the land itself protested. As to Cappadocia, the Pontic rulers had not forgotten that this country and Cappadocia on the sea had been formerly united, and continually cherished ideas of reunion.
