Acta Sanctorum (c. 200 AD?-c. 1590s?)
Originally published over a period of 300 years from 1643 by the Société des Bollandistes, the Acta Sanctorum is a collection of critical hagiography that examines the lives of Christian saints, organised according to each saint's feast day. The collection preserves authentic source material collected from the archives and libraries of religious houses by the Jesuit editors, known as Bollandists after the founder and first editor of the work. It records details of domestic and public life and provides information on a number of topics, such as social and ecclesiastical history, art and architecture, literature, folklore, and ethnology. It forms, therefore, a major source of information about early Christian and Mediaeval Europe. The Library holds Jan. I to Oct. XI in the edition published in Paris between 1863 and 1870 and Oct. XII to Dec. Propylaeum in editions published at various times between 1875 and 1940. The text is in Latin.
