Ephialtes, from the 1863 edition of Collin de Plancy's Dictionnaire infernal.
Featured on PDR in the essay Defining the Demonic
Although Jacques Collin de Plancy’s Dictionnaire infernal, a monumental compendium of all things diabolical, was first published in 1818 to much success, it is the fabulously illustrated final edition of 1863 which secured the book as a landmark in the study and representation of demons. Ed Simon explores the work and how at its heart lies an unlikely but pertinent synthesis of the Enlightenment and the occult.
