Banker marks

Refers to marks used in Western architecture to identify the mason who carved the stone at his banker in the building lodge. The origins and intended use of banker marks varied through history, and are not entirely understood. Early banker marks were apparently used to assure responsibility and quality control in a large building project where a number of less-skilled masons were employed. By the 13th century, banker marks often identified stones carved by specific task, so that the masons could be paid appropriately. Bankers marks typically appear on the work of masons less skilled than the freemasons, who carved moldings and figures. The banker mark eventually came to identify the mason himself. It was often assumed as a signature outside the context of the building site.
