This wondrous book spurred an entire body of work for me. It is a beautifully written mix of history, mythology, fiction and science. Laid out in 12 chapters which correspond to the twelve hours of the night, Dewdney explores global cultural nighttime customs, bedtime stories, the physics behind sunsets, and the mechanics of sleeping and dreaming. A reviving book of essays about how we spend those hours in darness. Highly recommended!
