The god of this world. The word in Syriac means riches. (See Milton: Paradise Lost, bk. i. 678.) His speech in the council is book ii. 229, etc.
In Spenser's Faërie Queene,
Mammon says if Sir Guyon will serve him he shall be the richest man in the world; but the knight says money has no charm for him. Mammon then takes him to his smithy, and tells him he may make what orders he likes, but Guyon declines to make any. The god then offers to give him Philotine to wife, but Guyon will not accept the honour. Lastly, he takes him to Proserpine's bower, and tells him to pluck the golden fruit, and rest on the silver stool; Sir Guyon again refuses, and after three days' sojourn in the infernal regions is led back to earth. (ii. 7.)
