The Practice of Light

Gratefully acknowledging the Sächsiche Landesbibliothek- Staats- und Universitätsbibliothek Dresden (the delightfully abbreviated SLUB) for the beautiful engraving of Wenzel Jamnitzer's geometric figures from the 1568 Perspectiva Corporum Regularium

the cover of The Practice of Light is now set, with a publication date of September this year. I just saw the endorsements, which genuinely brought a tear to my eye. Eight long years in the making, and many many people to thanks. Very much looking forward to turning it out into the world to see what you all make of it.
As some of you know, this was long called "Glory: The Practice of Light". MIT's marketing people, after some hard work, persuaded me that the risk of attracting neo-con religious types (and driving away the more militantly secular) wasn't worth the candle. "Glory" is still how I think of it: somehow we polytheists have to recapture the high ground from organised religion.
