Umm el‐Jimal cathedral, Jordan: inscriptions and radiocarbon dates

Radiocarbon dating of organic inclusions from the mortar of Umm el-Jimal cathedral's apse confirms that an inscription found on its floor dates to AD 556, aligning with the Bostra calendar and validating previous stylistic and architectural dating. The study used X-ray diffraction and microscopic analyses to characterize the lime-based, ashy mortar with high charcoal content, supporting the conclusion that the cathedral's construction fits a broader trend of increased church-building activity in northeast Jordan between AD 550 and 650.
