Abstract:

Ten timbers from the spire scaffold of Salisbury Cathedral were dated using a combination of ring‐width dendrochronology, stable oxygen isotopic dendrochronology and radiocarbon dating. Seven timbers were coeval and assigned a combined empirical felling date range of 1352–1378, which was further refined to 1351–1359 (OxCal 95.4%). These results would indicate that the scaffold was not a 1320s construction but instead built later in the 14th century. The remaining sampled timbers produced a precise felling date of spring 1737 and are coincident with documented repair work in 1738.

Abstract:

The Feeding Anglo-Saxon England (FeedSax) project applied scientific methods to bioarchaeological remains, in order to shed new light on medieval English agriculture. The methodology included an extensive radiocarbon dating programme which, besides helping to date developments in farming at selected case study sites, proved informative in its own right. This paper discusses the key implications of this programme’s results, with regard to the general problems of dating medieval settlement phases. First, it has allowed us to devise a new ‘universal’ chronological schema which aligns conventional phases with the precision currently attainable from calibrated radiocarbon dates. Second, it has revealed frequent discrepancies between the radiocarbon dates of organic remains and their original phasing — usually based upon associated ceramics — often resulting in chronological refinements or revisions, and sometimes revealing hitherto unrecognised periods of activity. In particular, the results highlight that ceramic-based phasing often underestimates the age of organic remains.

Abstract:

Abstract The programme of radiocarbon dating undertaken at Stanwick, Northamptonshire, demonstrates the value of scientific dating of Romano-British sites, including those with good pottery sequences and large numbers of datable coins and other finds. It has refined and clarified the chronology and phasing of the site, particularly in its final phase of occupation. It confirmed some of our original dating of the human burials, and showed other dates were significantly wrong. It also addresses issues relating to the calibration of radiocarbon dates and dietary isotopes in the period. This has enabled us to identify activities, material culture and burial practices current at Stanwick and elsewhere in the immediate post-Roman period.
