William Blake never went to any school at all and was apprenticed to a trade. Yet somehow his works display a knowledge of everything from Newton's physics to Hobbes, Hume, Spinoza, Swedenborg, Dante, Homer, Chaucer &c &c &c. Could it be he didn't write his works and is just a front for somebody more eligible?

We know though how he did it, because there is much better documetation for the 19th than the 16th century. He was an incredibly smart, imaginative, and hardworking Londoner--rather like William Shakespeare.
