The initial date of the era in B.C. 312 is also established by the dates on several coins, of which one of Hadrian bears the date HKY, and another of Caracalla bears the date HKΦ. As Hadrian began to reign on the 11th August 117 A.D., and Caracalla on the 8th April 217 A.D., the first year of the era referred to must have included the dates of 8th April and 11th of August 311 B.C.† - [Previous: c11.1](https://indike.org/pramana/ins.epigraphy.cunningham-1883.c11.1) - [Next: c11.3](https://indike.org/pramana/ins.epigraphy.cunningham-1883.c11.3) - [Up: c11](https://indike.org/pramana/ins.epigraphy.cunningham-1883.c11) --- Source: [https://indike.org/pramana/ins.epigraphy.cunningham-1883.c11.2](https://indike.org/pramana/ins.epigraphy.cunningham-1883.c11.2) · Pramāṇa
