Late Roman and Byzantine Weights in the Collection of the Istanbul Archaeology Museum
Researching through the museum catalogues and private collections, weights were classified in eight main types:
- Spherical commercial weights,
- Circular commercial weights,
- Square commercial weights,
- Octagonal commercial weights,
- Circular coin weights,
- Square coin weights,
- Octagonal coin weights, and
- Bowl-shaped weights
Types 2, 3, 5 and 6 form the majority in number.
While type 1 consists of Late Roman weights, the rest consists of Byzantine weights. All the weights except the bowl-shaped ones, are engraved or punched on the top with the denominational mark, mainly inlaid with silver. The largest unit is a 3 libra weight which weighs 975 gram and it is among the circular commercial weights (type 2).
Consequently, the above-given information is the basis of the tentative catalogue. Nearly all the weights were classified and catalogued by their forms and units, as well as their chronology. With some unique examples in the collection, the catalogue will make a contribution to the studies in the area of Byzantine weights. The catalogue will be published in the first half of 2010.
