Corpo Cronológico (Memory of the World)

The Corpo Cronológico is one of the most remarkable documentary collections of the early modern period held in Portugal. It brings together some 83,212 handwritten documents, distributed across more than five hundred bundles, which span a chronological arc from the twelfth century to the end of the seventeenth, with particular concentration in the fifteenth century and the first half of the sixteenth — precisely the golden age of the Discoveries. In 2007, the collection was inscribed on UNESCO’s Memory of the World Register, marking the first time that the programme had recognised a Portuguese documentary corpus of this nature.

An artificial collection assembled in the eighteenth century

Unlike an organic archival fonds, the Corpo Cronológico is an artificial collection: it was put together by design, grouping loose documents of diverse provenance and ordering them by chronological criterion. The initiative came from Manuel da Maia, chief keeper of the Torre do Tombo, who between 1756 and 1764 — in the aftermath of the 1755 earthquake, which also affected the royal archive — gathered originals issued chiefly from the Secretariat of State for the Affairs of the Kingdom and from the crown courts. Later archive officials continued to add pieces to the original core.

This genesis explains its structure in three parts, ordered by date, and the enormous typological diversity of the pieces: royal letters, charters, diplomatic correspondence, accounts of voyages, judicial records, instructions to captains and administrative regulations sit side by side, united only by chronological succession.

The strength of the Corpo Cronológico lies not in a single exceptional piece, but in the density of the whole: it is the cross-reading of thousands of documents that makes it possible to reconstruct the daily workings of the administration of an empire on a planetary scale.

A testimony to the Discoveries on a global scale

The value that justified UNESCO’s distinction lies in the geographical and thematic coverage of these manuscripts. They document the relations of Portugal — and, by extension, of Europe — with the peoples of Africa, Asia and Latin America, touching on the political, diplomatic, military, economic and religious history of countless territories. Among the matters addressed are European diplomacy, confrontations with Ottoman power, astronomical observations in the service of navigation, disputes of maritime law and the ecclesiastical organisation of Brazil.

For this reason, the Corpo Cronológico serves as a first-rate source for the study of the maritime expansion, complementing equally memorable individual documents such as the Letter of Pero Vaz de Caminha, the Journal of Vasco da Gama’s first voyage or the Treaty of Tordesilhas, all of which are also inscribed on the Memory of the World.

Conservation and access

The collection is held at the Arquivo Nacional da Torre do Tombo, successor to the old royal archive that operated for centuries in a tower of the Castelo de São Jorge. Since 1990, the holdings have occupied the building on the Alameda da Universidade in Lisbon. A good part of the Corpo Cronológico has been digitised and made available online, which has made it possible for researchers around the world to access documentation once reserved for on-site consultation.

Alongside other assets recognised under World Heritage and UNESCO’s programmes in Portugal, the Corpo Cronológico affirms the documentary and archival dimension of Portuguese cultural heritage, reminding us that heritage is not confined to monuments: written memory too constitutes a legacy of universal value.
