William Blake was an English poet, painter, and printmaker. Throughout his works, Blake explored themes of social justice, humanity's relationship with nature and spirituality, and opposition to oppressive institutions and authorities. He used recurring imagery of nature, religion, and human suffering to critique issues like child labor, slavery, and the mistreatment of women. Though unappreciated in his time, Blake sought to empower imagination and human senses as a way for people to achieve a higher spiritual state and work for social change.
