Bronze steelyard weight
Roman Britain, probably 1st or 2nd century AD
From the City of London
This weight, for a statera, or steelyard, is in the
form of a bust of a bearded and balding man. It is possibly meant
to represent a philosopher. The lid in the head allowed the
hollow-cast bronze body to be filled with lead to achieve the
desired weight. In its current state it weighs 6.812 kilograms.
