Resumo: An old topographic compass displayed in a showroom of the Museu de Astronomia e Ciências Afins (MAST), in Rio de Janeiro, Brazil, took our curiosity namely because of its resemblance to a theodolite, described by J.H. de Magellan. Not many things were known about its previous history. From the different documents studied, and the characteristics of this singular theodolite, it must have belonged to the collections of instruments acquired for the Brazilian border demarcations undertaken after the Santo Ildefonso Treaty, agreed to by the Portuguese and Spanish courts in 1777. Several instruments were bought in London, and supervised and chosen by Magellan, the Portuguese instruments expert. We present arguments in favour of this conclusion.

Pouco era conhecido sobre sua história prévia. De acordo com os diversos documentos estudados e as caracteríticas desse único teodolito, ele deve ter pertencido às coleções de instrumentos adquiridos para a demarcação das fronteiras brasileiras realizadas após o Tratato de Santo Ildefonso, acordado entre as cortes portuguesa e espanhola em 1777. Vários instrumentos foram comprados em Londres, supervisionados e escolhidos por Magalhães, o perito português em instrumentos. Apresentamos argumentos que corroboram essa conclusão.Fundação Oswaldo Cruz2017-11-20T19:47:41Z2016-01-01T00:00:00Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10773/18902eng0104-597010.1590/S0104-59702016000300004Malaquias, Isabelinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-22T11:36:35Zoai:ria.ua.pt:10773/18902Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T02:53:45.553078Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
