Thanks for getting back, Brendan. The image of a slice or bread rising in the morning is a great image, whether it's out of the horizon or out of the toaster. I've often thought that in the Catholic Church the fact that the host is round, and lifted up by the priest in both hands is a very solar image. There's no absolute need for the bread to be in the shape of the sun. I noticed once in a Baptist church that they used slices of bread, torn roughly into pieces, and served on little platters instead. That made me wonder why Catholics use small white round pieces of rice paper for bread. The similarities between bread and the sun as symbols of life is undeniable. It's also a little bit reminiscent of the dragon eating the moon at a lunar eclipse. The image of loaves measuring the space then is very intriguing.
The Lull and Belmonte paper you refer to is great, very enjoyable to read. After reading your thread I felt I had a way into it. Actually I forgot to tell you Yve, if you look at the paper, page 27, there are some images, and in the one labelled III, there is a little solar boat just above Scorpio and Libra, which in later traditions is exactly where Ophiuchus would be, and may be Michael's predecessor.
