Notary

Also known as a notary public, this is a public officer authorized (among other duties) to certify documents and to record the fact that certain persons swear that something is true. Some authorities (47, 245, 274) believe the signing of the marriage contract (in which the notary plays an important part) is a take-off of similar scenes in grand opera, such as The Barber of Seville and Lucia di Lammermoor.
