v1.c31.63

In that portion of Pahlava history which comes after the Christian era, the period of the reign of Gondopharnes may be regarded as almost definitely fixed. The date of its beginning appears to be certain; and it is certain also that it lasted for at least 26 years. The evidence for this is supplied by a monument of this king's rule in the Peshāwar District commonly known as the Takht-i-Bahi inscription. It is dated in the 26th year of the king's reign, and on the 5th day of the month Vaiçākha in the year 103². There can be little doubt that the era is the Vikrama saṃvat which began in 58 B.C., and that, therefore, Gondopharnes began to reign in 19 A.D. and was still reigning in 45 A.D.
