The memory of the Inconfidência of the State of Minas Gerais is present on objects and documents located in the permanent exhibition or collected to the Historical Archive. Noteworthy is the transcript of the period of 72 procedural documents of Autos de Devassa, in addition to the seventh and final volume, which contains the sentence declaring the inconfidentes guilt and the certificate of execution of Tiradentes.
Single manuscripts are also part of the collection. O Parnaso Obsequioso e Obras Poéticas (1768), Cláudio Manuel da Costa; inventory of the estate of Maria Dorotéia Joaquina de Seixas, Marília de Dirceu; documents of autographs of inconfidentes in the exercise of their functions, such as the map of arming a horse, made by Tiradentes, and provisions passed by Tomás Antônio Gonzaga in the position of Ombudsman.
Among the highlights printed is the publication of Récueil des loix constitutives des colonies angloises, confederées sous la denominacion d’Etats-Unis de l’Amerique Setentrionale, clandestine edition of 1788, which served as a reference to the inconfidentes and was seized with Tiradentes. There is also the first edition of the books of Marília de Dirceu, by Tomaz Antonio Gonzaga (1789), and Works by Cláudio Manuel da Costa (1768).
The institution keeps, in the Hall of Inconfidentes, personal belongings of the conspirators. The watch belonged to Tiradentes, robes and vestments that belonged to Father Manuel Rodrigues da Costa. There is also a work in engraving printed on fabric, attributed to Maria Dorotéia Joaquina de Seixas, Marília de Dirceu.
You can also find furniture belonging to the contractor João Rodrigues de Macedo, one of the largest fortunes (and also one of the main debtors) of the captaincy, who built and lived in one of the most luxurious private residences of Ouro Preto, the Casa dos Contos (The House of Coins). In the place, some meetings of inconfidentes were held, which suggests that some of these furniture have been used by participants in the movement.
