Alcobaça’s Codex Calixtinus: the Liber Sancti Jacobi and Memory of the World

Alcobaça’s Liber Sancti Jacobi, held at the National Library of Portugal under shelfmark ALC. 334, is a medieval witness to the circulation of texts about St James. It belongs to the joint Portugal–Spain inscription on UNESCO’s Memory of the World International Register, approved in 2017, bringing together the Compostela cathedral codex and other medieval copies. This recognises documents and differs from the Monastery of Alcobaça World Heritage inscription.

A manuscript with its own identity

The name Codex Calixtinus associates this textual tradition with Calixtus II. Strictly, it identifies the manuscript in Santiago de Compostela Cathedral, Spain. The Alcobaça copy belongs to the same tradition but has its own content and history. The nomination form dates it to about 1175, an approximate date rather than a documented day of production.

The volume contains texts about Martin of Tours and St James. The Jacobean section occupies folios 103v–215v in the numbering used by Santiago Ruiz Torres’s study. It preserves the books of miracles and the translation of the saint’s relics, alongside selected other Liber texts. It does not reproduce all five books in the Compostela manuscript’s order.

These choices offer evidence about readers’ interests and textual transmission. Scholarship distinguishes Alcobaça provenance from unresolved questions about where the copy was made and how it reached the monastery. Membership of a monastic collection alone does not establish a particular scribe or place of production.

From Alcobaça to the National Library

The BNP preserves the codices collection from the Cistercian monastery’s library, incorporated following the nineteenth-century dissolution of religious orders. The National Library in Lisbon holds ALC. 334 today. Visiting Alcobaça can illuminate its monastic context, but does not guarantee access to the manuscript.

The 2017 inscription also includes witnesses in Spanish institutions. A shared register entry does not place the Compostela codex in Portugal or automatically recognise every surviving Liber manuscript.

Starting your research

Consult the BNP collection and search for ALC. 334. The musicological study supplies an index and explains the foliation systems, helping readers compare the selection of texts. Before requesting images or the original, check current conditions with the Rare Books and Manuscripts service; a digitisation link cited in an older publication may no longer work.

Continue with the Portuguese Ways of St James and the Commentary on the Apocalypse manuscripts. These related routes and documents have their own identities and inscriptions.
