Dating the City Wall, Fortifications, and the Palace Site at Pagan

Abstract

The strengths and limitations of radiocarbon dating as applied to samples taken in and around the walled city center of Pagan, in Burma, are addressed. The last thousand years in mainland Southeast Asia remains a difficult period to date absolutely because of two critical issues. The first is the use of wood from long-lived species, such as teak, in archaeological contexts. The archaeologist dating such material must be aware of the significance of a date range that relates to the period when a tree was alive rather than to when the wood was actually used in the construction or reconstruction. The second issue stems from the character of the radiocarbon calibration curve for this time period. Several plateaux exist in the curve that seriously broaden the calendar age ranges deriving from uncalibrated high-precision dates. These effects are outlined using two areas sampled for radiocarbon dating at Pagan: the fortifications near the Tharaba Gate and a site within the old city walls, Inventory No. 1590, known as the palace.

“…Age calibration ranges (by convention expressed as CalBP: Calibrated years Before Present) for the Shea's Creek samples were determined using the Bayesian calibration program BCAL (James, 2000). This statistical program was used because the calibration curve is irregular as a result of mapping a radiocarbon age, with its symmetrical normal probability distribution, on to the irregular calibration curve that has an irregular probability distribution (Buck, 1996;James, 2000;Grave and Barbetti, 2001). The calibration curve cannot be treated statistically in the same way as radiocarbon ages, hence the use of the program.…”

Radiocarbon and the Old World Archaeology: Shaping a Chronological Framework

“…Several ancient sites are 14 C dated in Burma (e.g. Hudson et al 2002;Grave and Barbetti 2002), Laos (e.g. Sayavongkhamdy and Bellwood 2000), and Cambodia (e.g.…”
