organic material for absolute dating. An Acacia charcoal sample collected from the above exposed surface was sent to Groningen Radiocarbon Laboratory (NL) for AMS dating. It yielded the following result 160±30 uncal BP (GrA-44671). Although its calibration is rather problematic, given that the curve at this point is highly fluctuating with several interceptions, most probabilities indicate that the pillar was erected between cal AD 1720 and 1828 (47.6% at 2 sigmas, according to OxCal 4.10: BRONK RAMSEY, 2009),although another interception suggests a much more recent date (fig.6).
