This dissertation aims to study the Portuguese tiles in the cloisters and the consistory room of the building belonging to the Third Order of Franciscans in Salvador, Bahia, the iconography of which depicts, respectively, scenes of the festival (Entrada) held to celebrate the wedding of D José, Prince of Brazil, with Dona Maria Ana Vitoria de Bourbon, Princess of Asturias, on 12 February 1729, and ten views of the eastern part of the city of Lisbon. Although it deals with an object of a pictorial nature and one of great documentary value, since it constitutes a unique record in tiles of the capital of the Portuguese empire before the 1755 earthquake, the thesis seeks to locate itself on the theoretical frontier of the art history and of cultural history. The tiles are analysed as a symbolic representation of Portuguese baroque political culture during the reign of D. Joao V. The research reveals how these particular tiles deviate from the typical thematiciconographic model of Franciscan temples of the Northeastern Franciscan School in which tiles have predominantly had religious themes. The thesis also reflects on the specificities of joanine monarchical power, its persuasive practices which allied Catholic religion to grandiloquent ceremonial apparatus. In the context of the colony the installation of the tiles in the temple of the Franciscan brothers in Salvador, comprising secular scenes depicting the royal cerimonies, is an evidence of the privileged relationship between the Portuguese crown and the members of the Third Order, who were drawn from the local landowning elite and who were the principal contributors of the tax imposed for the royal wedding.
