Note 9 — Chapter I · HISTORY OF THE PAVEMENT
Reading edition
Apparently the working foreman or clerk of the works. The terms used to describe the different offices are both confusing and misleading, but it is evident from the documents that the Rettore or Operaio as he is indifferently called, was a person of much greater social importance than the Capo-maestro, and not really a workman at all. He was the official Director of the Cathedral works, the Steward in fact: the Capo-maestro being his head workman.
