Roman & Byzantine Scale Weight Sets

In ancient Roman and Byzantine commercial markets (macella), merchants, goldsmiths, and money changers carried compact, multi-piece weight sets to evaluate coins, precious metals, and high-value spices. These weights were precisely cast and lathe-finished in exact graduated fractions of the Roman pound (libra ~327g) and its primary division, the uncia (~27.3g).

Concentric Ring Decoration & Verification

The incised concentric circles on the top surfaces served as official lathe-turning markers and verification guidelines indicating that the piece had been shaved and calibrated to standard weight fractions by civic market officials (agoranomoi / zygostates).
