Denys the Carthusian; Denys van Leeuwen; Ecstatic Doctor
Last of the Schoolmen, born Ryckel, Limburg (now Belgium), 1402; died Roermond, Dutch Limburg, 1471.
After studying at Zwolle and Cologne, he entered the Carthusian monastery of Roermond, where he acquired a reputation for great sanctity.
Though not infrequently styled Blessed, the cause of his beatification has never begun.
Denys was a prolific writer; his works form a complete summary of medieval scholastic teaching.
He was, however, a compiler rather than an original thinker.
