Abstract
A distinct feature on many Middle Bronze Age scarabs from the southern Levant is the presence of chromatic marks on the backs of these objects, often described as longitudinal lines. Previous explanations have fallen into one of three proposals: either the product of production-related techniques related to firing and glazing, intentionally applied marks, or the byproduct of use-wear related or depositional practices. To date, no critical investigation of these enigmatic marks has been published and thus no consensus reached. However, through new high-resolution photography of the stamp seals from the sites of Lachish and Megiddo in the southern Levant, a systematic analysis was recently permitted. This paper presents the results from a study on these enigmatic marks and a discussion on what the new photography reveals about previous interpretations and possible new directions for the study of this corpus.
