Mammon, the least erected spirit that fell from Heav'n, for even in Heav'n his looks were always downward bent, admiring more the riches of Heav'n's pavement, trodd'n gold, than aught divine or holy else enjoy'd in vision beatific: by him first men also, and by his suggestion taught ransack'd the Center, and with impious hands rifled the bowels of their Mother Earth for treasures better hid.
-John Milton, Paradise Lost
