Ring‐Width Dendrochronology, Isotopic Dendrochronology and Radiocarbon Dating of Timbers From the Spire Scaffold of Salisbury Cathedral, Wiltshire, England

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.
