High Quality Content by WIKIPEDIA articles! Vala, or The Four Zoas refers to one of the incompleted prophetic books by English poet William Blake, begun in 1797. The titular main characters of the book are The Four Zoas: (Urthona, Urizen, Luvah and Tharmas), who were created by the fall of Albion in Blake`s mythology. It consists of nine books, referred to as "nights". These outline the interactions of the Zoas, their fallen forms, and their Emanations. Blake intended the book to be a summation of his mythic universe but, dissatisfied, he abandoned the effort in 1807, leaving it unfinished and unengraved.
