About the end of 45 the conflict between the brothers broke out again, and from 46/47 to 47/48 they were engaged in a struggle which terminated with the death of Vardanes. He was assassinated by the nobles, probably at the instigation of Gotarzes, while engaged in the national sport of the chase.

From this period onward the dates given in this volume are calculated on the basis of a readjustment in the calendar which took place between the years 16/17 and 46/47, almost certainly in the latter year. The 19-year cycle of intercalation introduced in 747 had been employed without change since 367  The calendar year was again brought into conformity with the solar year by the insertion of a full month so that henceforth the Macedonian month Xandicus instead of Artemisius corresponds to the Babylonian Nisan, the beginning of the year.
