Bollandist

The Bollandist Society (French: Société des Bollandistes) are an association of scholars, philologists, and historians (originally all Jesuits, but now including non-Jesuits) who since the early seventeenth century have studied hagiography and the cult of the saints in Christianity. Their most important publication has been the Acta Sanctorum (The Lives of the Saints).[1] They are named after the Flemish Jesuit Jean Bollandus (1596–1665).
