Readers may be aware of the nested bowl weights
from medieval Byzantium
, but they may not know that similar weights
were used in the Roman
imperial period (I certainly wasn't).
Shown below is a superb
set of weights
from Feldkirchen (Austria
), ranging from 20 libra to 1 oz. These types
were likely copies of the official master weights
held in the temple of Castor
, and sent to the provinces as local reference weights
For details of these "Castor
see Luciani & Lucchelli on the Academia site:https://www.academia.edu/25658432/Pondera_exacta_ad_Castoris
Also shown is a 6 oz bowl
found in the Levant.
