Ancient Jewish bakers in Israel already marked their bread with the shape of a menorah. Proof with this clay bread seal about 1500 years old, discovered east of the city of Acre in Israel during excavations conducted by the Antiquities Service. On the face of the seal is engraved a seven-branched candelabrum, while at the end of the handle are engraved Greek letters. According to Prof. Leah Di Segni, they might reflect the name "Leontius," common among Jews at that time—perhaps that of the baker.In Roman times, the bread seal was part of an organized control system: it indicated the identity of the baker or the bakery owner, and sometimes even that of the authority responsible for overseeing the city's bread supply.
