It is believed that the problems of absolute chronology are almost solved, at least for historical periods. It is assumed that written sources, such as inscriptions and coins, found in almost all the settlements of these epochs, provide sufficient information for correct Dating of archaeological layers. In fact, everything is much more complicated, because, most often, scientists are trying to get exact dates.As far as Central Asia is concerned, the texts are not very numerous and usually concise, the science of paleography is inaccurate, and coin finds are also infrequent. And more than that, coinsthey are very rarely associated with the exact location, and in this case they only give terminusantequem non, their attribution with any ruler remains the subject of controversy, and our absolute Dating fluctuates. Chronological definitions are mostly relative and based on the dates of previous or subsequent levels, which, in turn, they are not very accurately dated. Only some of them, in very rare cases when information comes from outside, for example, import or imitations of it are detected, allow us to determine the dates more reliably.
