Keys were symbols of responsibility as staves were of authority. When the warden of the castillo made his oath of fealty to defend his post he took charge of the keys of the fort and marched through its precincts with the public notary, locking and unlocking the gates. [Note 63: Juan Moreno y Segovia, affidavit 11/2/1663, enclosed with Joseph de Prado and Domingo de Leturiondo 11/4/1663] A similar ceremony was observed with a new treasury official, who received his key to the treasure chest and immediately tried it. In legal documents this chest was sometimes called the “coffer of the four keys,” from the days when there would have been four padlocks on it, one for each official. At important treasuries another key was frequently held by the viceroy, the archbishop, or an audience judge, who sent it with a representative when the chest was opened. The royal officials resented this practice as impugning their honor. (Bushnell KC)
