Apollyon (Gr., 'the destroyer'), or ABADDON (Rev. ix. 11; cf. Job, xxvi. 6, xxxi. 12), the same as the Asmodeus of the Book of Tobit (iii. 8). See ASMODEUS. It is with Apollyon that Christian fights his hardest battle in the Pilgrim's Progress, and it is to this literary use of it by Bunyan that the name now mainly owes its currency.
