scorpio the demon - "the dark centre of the cosmos"
Scorpio, Chartres Cathedral, France
"Leo, which is ruled by the Sun, is often placed on the facade of a cathedral so that it is the first of the Evangelists' symbols to receive sunlight in the course of the day. Scorpio, connected with hell and the dark centre of the cosmos (according to the medieval view of the world), is correspondingly placed so that it it is the last to receive the light."
