The aim of the research presented in this report was to precisely obtain information concerning the origin of pottery types common in Crusader Acre. Thus, laboratory analyses, both elemental and petrographic, were applied on a fairly extensive number of samples, focusing on two broad ceramic categories: wares typical of Levantine sites of the Crusader period and wares belonging to the Zeuxippus Family. This study enabled us to distinguish between a ‘prototype’ and ‘derived’ or related productions—an important step in the attempt to prevent confusion within the Zeuxippus Family.
