The chronology of Julianos Church, Umm el‐Jimal, Jordan: AMS radiocarbon dates of its synthronon

New radiocarbon dating of Julianos Church’s synthronon at Umm Al-Jimāl, Jordan, resolves longstanding debates on its chronology. The analysis confirms that the church underwent a high-quality renovation in the late sixth century (565–607 AD), while its original mosaic floor likely dates to the second half of the fifth century (465–507 AD). This challenges earlier claims suggesting an earlier construction date, aligning instead with regional archaeological evidence. By examining organic inclusions from mortar samples—including pavement, bench tiers, and throne steps—the study provides precise dating that supports a phased development model for this significant early Christian site.
