The first edition of the book by Pomponatius, which was the earliest of his writings, is excessively rare, but it was reprinted at Venice just a half-century later.

It is in his De incantationibus, however, that he speaks especially of devils.

As to Pomponatius, see, besides these, Creighton's History of the Papacy during the Reformation, and an excellent essay in Franck's Moralistes et Philosophes.

For Agrippa, see his biography by Prof.Henry Morley, London, 1856.

For Bodin, see a statement of his general line of argument in Lecky, Rationalism in Europe, vol.i, chap.
