Acta Sanctorum

Acta Sanctorum is an encyclopedic text in 68 folio volumes of documents examining the lives of Christian saints, in essence a critical hagiography, organised by the saints' feast days. The project was conceived and begun by the Jesuit Heribert Rosweyde. After his death in 1629, the Jesuit scholar Jean Bolland continued the work, which was gradually finished over the centuries by the Bollandists, who continue to edit and publish the Acta Sanctorum.
