The Song of Los is an epic poem by
William Blake first published in 1795 and considered part of his
prophetic books. The poem consists of two sections, "Africa" and "Asia": in the first section Blake catalogues the decline of morality in Europe, which he blames on both the African slave trade and enlightenment philosophers, whereas in the second section he describes a worldwide revolution, urged by the eponymous
Los.
The illustration here is from the book's frontispiece and shows Urizen presiding over the decline of morality.Illustration: William Blake
