The HORAE project
A textual exploration of Books of Hours
Tell me more


HORAE (Hours - Recognition, Analysis, Editions) is a cross-disciplinary research project studying religious practices and experiences in the late Middle Ages through the books of hours, the absolute medieval best seller.

HORAE combines the research and expertise of three partners:

TEKLIA : Machine Learning applied to document analysis

LS2N Lab : Natural Language Processing for text comparison

IRHT-CNRS : book history and religious practices

Book of hours

Books of hours forms, with more than 5000 preserved manuscripts, a vast and crucial ensemble to understand the medieval mindset. Yet, their textual content is very scarcely studied, although the massive production of such a large number of manuscripts is a pivotal cultural and industrial phenomenon to the profound changes in the medieval religious life. Not only a proto-industrial book production arises and the economics of demand shifts to the economics of offer, but also the awakening of the individual and the internalization of faith take places in an increasingly church controlled world. Books of hours are at the same time deluxe objects, implying social staging, and intimate objects, with devotional, memorial and eschatological challenges.
