Email the author ON THE MATHEMATICAL ALGORITHM OF SOME ANCIENT DRACHMAS MINTING TIME
Abstract
It was selected three Dyrrachium drachmas issued between 229-30 BC of the "Treasure of Cehei" to establish minting time. There were measured dimensions, weights, and hardness. Finally they were subjected to X-ray diffraction determining the crystallographic parameter, grain size, and material relative deformation that existed at the measurements time. It was established the amount of silver as 96 – 98 weight %. Relative deformation was considered conclusive of all the results that led to the determination years of minting drachmas and those that were magister monetarius who supervised for, under whose authority coins were issued. They are, in order of age, Phereneikos in 164.5 BC, then Meniskos in 115 BC, and the last Xenon 103 BC.
Key words: ancient drachmas, XRD patterns, relative deformation
