Urizen is a character created by the English poet William Blake. He represents reason, law, and order, often depicted as a tyrannical figure who imposes restrictions on human creativity and freedom. Urizen embodies the rational mind, contrasting with the imaginative aspects of human nature. In Blake's works, particularly in the poem The Marriage of Heaven and Hell, Urizen is portrayed as a creator of a rigid, oppressive world. His character serves as a critique of Enlightenment rationalism, highlighting the dangers of excessive reason that stifles the spirit and imagination.
