CAMPS Lab: ‘When a Quarter is Analogous to Three-quarters: Quadrans in the De Divisionibus Temporum Tract of Laon, Bibliothèque Municipale, MS. 422.’

Paula Harrison (PhD Researcher, Ancient Classics, University of Galway) will be presenting on

‘When a Quarter is Analogous to Three-quarters: Quadrans in the De Divisionibus Temporum Tract of Laon, Bibliothèque Municipale, MS. 422.’

The Hiberno-Latin tract De divisionibus temporum (‘The divisions of time’) was an elementary work for the study of time reckoning (computus) during the early medieval period. This paper will explore a unit of these divisions, the quadrans or the quarter day. In particular, it will focus on an expanded version of this tract as it is transmitted in the early ninth-century manuscript Laon, Bibliothèque Municipale, MS. 422. This expansion in unique in that it preserves lesser disseminated materials which encompass both computus and grammar.
