In the old Roman Republic, notarii were public secretaries who were shorthand writers. As scribes became more and more common, they developed a service in the public marketplace to draw up
legal documents and other written instruments. Wax seals were used as signatures on documents.
Later, ribbons tied together multi-page documents, and wax seals on the knots showed that no one
had tampered with the knots. Thus, we came to have notary seals.
