Evidence for working practices

Process
Securing
Tool
Metal clamp/pin
Description
This image documents a hole left by the removal of a metal clamp. These clamps were made of iron around which lead was poured to stop them rusting. The purpose of these clamps was to fix the drums of the column in place but the demand for metal in the post-Roman period lead to the removal of most of them. This is from the very top of the Column of Trajan where a short section of fluting was included in the design.

2. Toolmarks

Process
Hollowing-out
Tool
Point
Description
The marks of the point chisel used by whoever removed this clamp can be seen all around the edges of this cut as well as at the back of it.
