Rediscovering Kleve’s Archive

The LACUNA project digitizes and transcribes Knut Kleve’s archive using advanced tools to preserve, publish, and make accessible his unpublished research on Herculaneum papyri and Epicurean theology.

One of the core activities of the LACUNA project is the recovery, HTR digitization, and dissemination of the unpublished documents of the Norwegian philologist Knut Kleve, one of the leading classicists of last decades who made a fundamental contribution to modern research on the Herculaneum papyri and Epicurean theology. Donated by his family in 2017, this private archive is preserved at the National Library of Norway in Oslo and contains heterogeneous materials: publications, handwritten notes (mostly in Norwegian), draft editions, correspondence with other scholars, hundreds of negatives, photographs and drawings of papyri, and related bibliography. Among the most significant materials for the project are those documenting Knut Kleve’s long-term work on Philodemus’ theological papyri, including preparatory texts and unpublished writings on Epicurean theology.

The working methodology includes the complete high-resolution digitization of the archive, the automated transcription of selected materials, and the preparation for publication of his unpublished monograph Physis theon. For transcription, the project will use the software Transkribus, with Super Models capable of handling multilingual and mixed-format archival materials, including handwritten and typewritten texts in Norwegian, German, Italian, Greek, and Latin.

The aim is to make Kleve’s unpublished documents accessible, searchable, and reusable: preserving an exceptional scholarly legacy and transforming it into a research resource for future studies on the Herculaneum papyri and Epicurean philosophy.

First mission in Oslo (25 February-11 March 2026): Archive reorganization

While waiting to resume the digitization of the Kleve Archive at the National Library of Oslo, the team carefully examined, reorganized, and systematized the materials. The archive is now accompanied by a newly updated catalogue, structured on a thematic basis to facilitate consultation and future research.

Second mission in Oslo (4 May-6 June 2026): Archive digitization

During the second mission at the National Library of Norway, the high-resolution scanning of the materials related to the theological section of the Kleve Archive was completed, covering both the documentary and photographic sections.
Acquired from the 1970s onwards, the photographs in the photographic section constitute a highly valuable historical record of the state of preservation of the papyri over time and, in some cases, document portions that are no longer preserved in the original material.

Mission in Oxford (19-31 May 2026): Archive digitization
