In our last blog post, we told the story of Islamic glass weights, “sanja”s. This time let’s take a look at the glass weights that were used in the Byzantine Empire.
Before the Islamic glass weights “sanjas”, glass weights were used in the Byzantine Empire.
Among the most common of these weights are the weights with depictions of governors (eparkhos) and emperors, and the weights with a box or cruciform monogram. In this post, you can see a selection of weights that belong to these two categories from the Suna and İnan Kıraç Foundation Anatolian Weights and Measures Collection.
In the glass weights that feature the governor, he can be seen holding the mappa, the linen handkerchief thrown to indicate the start of the games in the arena, or a sceptre, or both.

The dignitary can be identified as Ioannos “the Cappadocian” who was Praetorian prefect of Oriens. it is likely that the weight was produced between 538 and 541.
The weights that feature the emperors have halo around the emperor bust accompanied by monograms or writing. Jewellery such as diadems are seldom discernible. The use of the imperial image suggests government validation.
Unlike the lead and bronz weights that get corroded, the glass weights were easier to detect if tampered with. This made them preferable.

he was also the urban prefect of Constantinople.
Koyu mavi renkli ağırlığın ortasında bulunan figür, sağ elinde mappa adı verilen mendili tutar. Sol koldan geriye kalanlar, onun da sağ kol gibi yukarı kaldırılmış olduğunu gösterir. Büyük ihtimalle sol elde bir asa bulunuyordu. Büstün etrafında ΔHMOCΘЄNƔ yazılıdır. Figür bu yazı sayesinde Doğu illeri valisi olan Flavius Ieodorus Petrus Demosthenes olarak tanımlanabilir. Demosthenes bir sure de Konstantinopolis valiliği yapmıştır.
Byzantine glass weights usually were disk-shaped. These were stamped with busts of people surrounded by a Greek inscription or with monograms that belong to governors of Constantinopolis and other important cities that had the authority to mint coins.

Byzantine glass weights were frequently found in archaeological contexts that left little to doubt about their function. In the Kunszenmarton cemetery in Hungary, glass weights were found among a balance with two scales and numerous metal weights.
Similarly in the Sardis excavations in the city of Manisa, glass weights were found along with bronze weights in two different contexts: in a complex with 19 shops and in a house in the suburbs of the ancient city. The discovery in a room of the house in the suburbs is the largest discovery of Byzantine weights from a discrete archaeological context
