The importance of the seals were attested when another law provided a punishment for the forgery and altering of sealed documents. Simon de la Loubère remarked that the king's own authority was linked to that of his seal. In times of turmoil and dynastic conflict, exceptional importance was attached to the seals, as it was considered that the kingdom's power and authority laid with their custodian. These seals did not survive the sacking and destruction of the city by a Burmese army in 1767.
