Demonology and Devil Lore 1 & 2, by Moncure Daniel Conway, were both published in 1897.
Volume 2 deals primarily with the diabolic and with the Devil himself, his ethnic history and connected topics; themes like Ahrima.
Even in the 21st century the works offer fascinating missing links for both the academic and student of occult traditions.
Within the Demonology scope, this rare and mostly forgotten, almost 1000 pages thick masterpiece, remains unsurpassed in quality and completeness.
