Ancient bread stamp discovered

Archaeology makes the following discovery in Akko:

ACCO (JWN)—Israel Antiquities Authority archeologists have uncovered a ceramic stamp embossed with the image of the seven-branched menorah used in the Temple. The 1,500-year-old stamp was unearthed in a dig near the northern city of Acco (Acre).

Archeologists say it dates from the Byzantine period in the sixth century CE and was probably used as a “bread stamp” to certify baked goods as kosher. It was unearthed during a salvage excavation at Horbat Uza in advance of construction of the Acco-Karmiel railroad.

That's interesting that ceramics can be used to approve baked goods just as much as a simpler sticker can today.
