The logo of this podcast is an engraving by William Blake (1757-1827). 

Blake was an English poet, mystic, and visual artist, most famous for The Tyger and Jerusalem. His writing synthesises critiques of industrialism and discourses on the natural sciences with ancient prophetic messages. On this, Blake writes: "to labour in knowledge is to build up Jerusalem." 

His works have influenced writers ranging from beat poet Allen Ginsberg to futurist blogger Scott Alexander. Ginsberg had a life-changing vision of Blake when he was 22, and mentions Blake in his magnum opus Howl; Alexander draws heavily on Blake's mythology in his Kabbalah-punk web-serial UNSONG.
