<b>The Marriage of Heaven and Hell by William</b>&nbsp;is a book by the English poet and printmaker&nbsp;William Blake. It is a series of texts written in imitation of&nbsp;biblical prophecy&nbsp;but expressing Blake&#39;s own intensely personal&nbsp;Romantic&nbsp;and revolutionary beliefs.<br /><br />Like his other books, it was published as printed sheets from&nbsp;etched&nbsp;plates containing prose, poetry, and illustrations. The plates were then coloured by Blake and his wife&nbsp;Catherine.<br />It opens with an introduction of a short poem entitled &quot;Rintrah roars and shakes his fires in the burden&#39;d air&quot;.<br /><br />William Blake claims that&nbsp;John Milton&nbsp;was a true poet and his epic poem&nbsp;<i>Paradise Lost</i>&nbsp;was &quot;of the Devil&#39;s party without knowing it.&quot; He also claims that Milton&#39;s Satan was truly his Messiah.<br />The work was composed between 1790 and 1793, in the period of radical ferment and political conflict during the&nbsp;French Revolution. The title is an ironic reference to&nbsp;Emanuel Swedenborg&#39;s theological work&nbsp;<i>Heaven and Hell</i>, published in Latin 33 years earlier. Swedenborg is directly cited and criticized by Blake in several places in the&nbsp;<i>Marriage</i>.<br /><br />Though Blake was influenced by his grand and mystical cosmic conception, Swedenborg&#39;s conventional moral strictures and his&nbsp;Manichaean&nbsp;view of good and evil led Blake to express a deliberately depolarized and unified vision of the cosmos in which the material world and physical desire are equally part of the divine order; hence, a marriage of heaven and hell. The book is written in prose, except for the opening &quot;Argument&quot; and the &quot;Song of Liberty&quot;. The book describes the poet&#39;s visit to Hell, a device adopted by Blake from&nbsp;Dante&#39;s&nbsp;<i>Divine Comedy</i>&nbsp;and Milton&#39;s&nbsp;<i>Paradise Lost</i>.
