Casebooks Project

Watch Professor Kassell introduce the casebooks of Forman and Napier.

The Casebooks Project is a digital humanities project centred on 80,000 astrological consultations recorded by a pair of astrologer physicians from 1596 to 1634. The original manuscripts are held in the Bodleian Library, Oxford. Casebooks was funded by the Wellcome Trust from 2008 to 2019. The project's main outputs are:

  1. a digital edition
  2. a dataset
  3. a critical introduction
  4. a viewer for high-resolution images of all 64 volumes of the casebooks manuscripts, accessible through (1) and Cambridge Digital Library
  5. a critical edition of Forman's guide to astrological medicine
  6. full-text transcriptions of 500 cases.

The project was built around an 'engagement framework' to improve the project's research. These activities are detailed on the Casebooks news and events page.
