This study was aimed at testing a cost‐effective method based on comparing the rareearth element patterns in artefacts of known origin with patterns of potential rawmaterials, thus allowing the restriction/exclusion of working hypotheses onprovenance, and consequently a better focus of research funding. The methodtargets ceramics/materials of terrigenous origin. Lanthanoids and yttrium patternswere determined in 26 wine amphorae that had a well‐established geographical originfrom the Nuovo Mercato Testaccio in Rome, and these patterns were compared toplausible terrigenous materials from various ancient Roman regions. The point wasnot to pinpoint the origins of the material, but rather to rule out possible areas oforigin. On both a national and a regional scale, we were able to exclude some regionsof origin for these amphorae that would otherwise have been largely plausible. Thismethod does not require sampling from already known kiln/extraction sites.Moreover, if maps of all rare earth elements in soils become available on a regionalscale, it could be possible to obtain a level of discriminatory detail in the range of afew tens of kilometres.
