Visionary! William Blake, who lived from 1757 to 1827, understood suffering, called out injustice, pictured the Heavens, described more than one Hell, and did it all in immortal verse and unforgettable imagery. The painted postures of his angels, men, and monsters have influenced choreographers from Isadora Duncan to Mark Morris. His poetry—concentrated, kinetic, and politically empowering—inspired Bob Dylan, John Lennon, and Jim Morrison. On now at the Tate Britain, the biggest Blake show in almost 20 years, with over 300 original works. —L.J.
