ARCHiOx
ARCHiOx (Analysis and Recording of Cultural Heritage in Oxford) is a research and development partnership between the Factum Foundation, the Bodleian Libraries and the University of Oxford. It was launched in February 2022 and is directly linked to the ARCHiVe structure established at Fondazione Giorgio Cini in Venice, with generous support from The Helen Hamlyn Trust.
This project was established as an open collaboration that aims to demonstrate the importance and potential use of non-contact digital technologies for the study of materials housed at the Bodleian. The Bodleian Imaging Department was already investigating the use of x-ray imaging techniques such as multi-spectral imaging (which takes visible images in blue, green, and red and combines them with an infrared image and an X-ray image of an object) to effectively reveal hints of pigment, hidden drawings or writings beneath the painted and inked surface of various materials and objects.
These methods are often used in conservation and archaeology, but Factum Foundation proposed applying them for the first time to the surface of manuscripts, as a way to reveal new discoveries around the materiality of the objects themselves. Factum Foundation pioneered the use of the Selene Photometric Stereo photographic system, developed by Jorge Cano, Matt Marshall and the R&D and Engineering team at Factum Arte, on selected items from the Bodleian’s special collections. This was complimented with a 3D recording of surface reliefs using Factum’s Lucida 3D Scanner.
The results from the pilot year exceeded every expectation in both accuracy (with information recorded in the range of 25 microns) and speed of recording. Using the Selene Scanner allowed for complex and reflective surfaces (such as copper printing plates) and fragile objects (such as palm leaf manuscripts with minute Sankrit inscriptions) to be recorded with extreme precision. It also led to new theories and discoveries when applied to the recording of maps and manuscripts.
ARCHiOx was featured on several press articles, including:
- The Guardian
- BBC
- The Smithsonian Magazine
- National Geographic Historia
- La Vanguardia
- Ars Technica
On February 5, 2022, the Selene Photometric Scanner was installed at the Bodleian Libraries after four days of setting up and testing. The results, both in terms of colour and data, are remarkable. It is the first time that high-resolution data has been recorded at the Bodleian. The implications for the material culture of the book are significant and the hope is that many departments and college libraries will realise the importance of surface recording. Image and form are merged to reveal more about the objects in their care. [...] The relationship between digital recording, non-contact restoration and online/offline access has never presented more opportunities. This is a groundbreaking initiative. [...] Thanks to Helen Hamlyn and her advisors, Richard Ovenden and the great team at the Bodleian Libraries and everyone at Factum who commits so much time and energy to the understanding and preservation of cultural artefacts.

Shaded renders make it possible to view the surface texture of an original while removing their visible tone and colour. This allows for academic research from originals that contain textural details which are difficult to see and cannot be adequately recorded using traditional photographic techniques. Alternatively, the data may be used to produce 3D facsimiles from items within our collections, allowing the material nature of the original to be reproduced.
