province. Now if, with F. Corfini (37), we admit 
the commencement of the Parthian aera to have 
happened in the 525th year of Rome ; the 425th or 
426th year of the former and the 970th of the latter 
of thofe sera’s, wherein the Parthians undertook the 
Mefopotamian expedition, will nearly coincide. But it 
may be proved from a medal of Monnefes, defcribed 
by the (38) Marquis Scipio Maffei, in oppofition to 
(39) Dr. Vaillant, that this prince was not dethroned 
in the year of the Arfacid<e 423, but had two years 
afterwards the management and direction of the 
Parthian affairs : wherefore, notwithstanding what 
has been advanced to the contrary by that antiquary, 
he might flill have fat one or two years longer upon 
the Parthian throne. This may likewife be inferred 
from Dio, who mentions Vologefes as preliding over 
the Parthians, not in 198, but in 199, about two 
• years after their irruption into Melbpotamia. All 
which being with proper attention confidered, it will 
appear extremely probable, that the medal I have 
been endeavouring to explain was coined either in 
the 425th or 426th year of the Parthian tera, that is, 
the 197th of Christ; that the authority of (40) 
Arrian, (4i)Juftin, and (42) Athenasus, on which
