The Marriage of Heaven and Hell is a book by the English poet and printmaker William Blake. It is a series of texts written in imitation of biblical prophecy but expressing Blake's own intensely personal Romantic and revolutionary beliefs. Like his other books, it was published as printed sheets from etched plates containing prose, poetry and illustrations. The plates were then coloured by Blake and his wife Catherine.

Context: The ancient poets animated all objects with Gods or Geniuses, calling them by the names and adorning them with the properties of woods, rivers, mountains, lakes, cities, nations, and whatever their enlarged & numerous senses could perceive. And particularly they studied the genius of each city & country, placing it under its mental deity; Till a system was formed, which some took advantage of, & enslav'd the vulgar by attempting to realize or abstract the mental deities from their objects: thus began priesthood; Choosing forms of worship from poetic tales. And at length they pronounc'd that the Gods had order'd such things. Thus men forgot that all deities reside in the human breast.
