How Long Does a Memory Last? Bayesian Chronological Modelling and the Temporal Scope of Commemorative Practices at Aeneolithic Monjukli Depe, Turkmenistan

In this paper the history of one house and a human burial in the prehistoric settlement of Monjukli Depe, Turkmenistan, serves as a case study for the use of Bayesian chronological modelling to approach the reach of past memories. The method combines relative and absolute chronological data and aims not only at a more precise and robust chronology of past events, but also allows estimations of duration of particular processes. However, chronological models must be constructed with care, since the prior archaeological information significantly affects the output. The comparison of three alternative models for the Aeneolithic settlement of Monjukli Depe shows that prior information in modelling has a considerable impact on duration estimates for periods of the settlement history. The modelling chronology for Monjukli Depe allows the tracing of commemorative practices at a generational scale—the memory of Monjukli Depe House 14 was transmitted over several generations of inhabitants long after the house destruction. It is clear that houses possessed a great value in the social life of the settlement since local building histories were remembered over a long time.
