Blake's illuminated books, produced from 1783-1795, are remarkable examples of complex syntheses: of form - poetry and painting, and of subject - the real with the mythical. Blake created his own mythological creations to populate his poems and paintings: concepts and ideas became personified into universal representations. He used these mythological characters to explain and act out his singular view of history. Blake divided the nature of man into four personified elements: "Los, the imagination and eventual source of redemption, Urizen, the reason and vengeful Jehovah of the Old Testament as opposed to the merciful Christ of the New, Luvah, the senses, and Tharmas, the emotions". Each of these characters has an emanation, or female "offshoot", who is commonly a negative character attempting to dominate her male counterpart.
