fall. He appears in the connected works The Song of Los, America a Prophecy and Europe a Prophecy at the same time. In these works, he begins as a prophet in Africa that describes how Urizen gave laws to the people that bound the minds of mankind. This was accomplished through Los's children with Enitharmon: "Thus the terrible race of Los & Enitharmon gave / Laws & Religions to the sons of Har binding them more / And more to Earth: closing and restraining" (lines 44–46). The Book of Los, completed at the same time, continues from the story of The Book of Urizen and describes how Los fell and was bound in a human form. It also describes how Los, in turn, bound Urizen in a human form. In The Book of Urizen, Los is constantly at struggle with Urizen to control the world and the two represent opposites. However, this was to later change when Blake added two other beings in his later work. In the early works, however, the binary system is possibly similar to the imaginative and reason sides that Blake divided his own mind and a struggle between the two. He also felt that Los was closely connected to Christ, and that is why Los dominated within his myth. In Jerusalem (1804–1820), it is said that Los was the progenitor of Adam, Noah, Abraham, Moses, and the other Biblical spiritual leaders. The work also describes the Four Zoas that are four parts that were united in Eternity but exist in a state similar to a giant after their fall. These four parts include Los and Urizen along with Tharmas and Luvah. The Four Zoas appear also in 2nd edition of Vala, or the Four Zoas (1807) and Milton: a Poem. In Milton: a Poem (1804–1810), Los appears as a flaming sun. This view of Los and the sun is similar to a description in a poem that Blake included in a letter (22 November 1802) that he wrote to Thomas Butts, and he believed that in the vision he was able to unite with Los. In Vala, or the Four Zoas, Los witnesses a vision of the Lamb of God being sacrificed to reveal his spiritual side while Urizen and the Synagogue of Satan work against Christ and are the ones who condemn him to death. After the Synagogue of Satan promotes Deism, Los seizes
