This article examines the use of royal emblems in Luso-Brazilian calligraphy during the eighteenth century. It is based on the analyses of a book written by Manoel de Andrade de Figueiredo entitled “Nova Escola para aprender a ler, escrever e contar” (“A New School for learning how to read, write and count”), published in Lisbon in 1722. The analyses helped to find important symbols used by the royal house of Bragança drawn as calligraphic ornaments merged with moralizing texts. They were among models of letters and other ornaments that were meant to be copied by apprentices. Several of these models appeared decorating public and private administrative documents in Brazil in the eighteenth century. There are two main aspects discussed in this paper: Firstly, the references and motivations of the author to spread the virtues of king D. João V and secondly, the necessary translations done by artists and by those who requested them.
