An aspect of local lamp production in the western Pontic region: the case of lamps of types Hayes/Saraçhane 9 and 10

Lamps of the Hayes 9 type were produced in huge quantities in the state workshops of the Eastern Roman Empire and in the Western Pontic ateliers, where the Hayes 8 lamps were also manufactured, especially in Constantinople and Halmiris. The shape of the lamps and the fabric argue in favor of this assumption, further supported by the dating of contexts recorded during the excavation of Dobrogean sites. Thus, the Halmyris workshop complex appears to stand out among the lamp-producing centers, at least in the Black Sea area, during Justinian’s reign.
