I'm always fascinated by histories of things you'd never imagine there were histories for (e.g. skunks, masturbation--both coming up in my to-read stack), and this history of night caught my eye at once. I happened upon Ekirch's excellent nocturnal emission reading an article about pre-electricity sleep habits, in that there used to be "first sleep" and "second sleep", separated by a short interval of wakefulness during which people prayed, had sex with each other, or, perhaps most importantly, laid there and thought about things, all things we either do too much or not enough of. This thesis stems largely from Ekirch's researches on what our medieval and early modern forebears thought of and did from dusk til dawn.
Close is broken up into different sections of different aspects of night, some expansive, some fascinatingly nichey. There are excellent sections on sleep (of course), crime, working at night, night and religion, witchcraft, falling into holes, tripping over things, curtains, beds, prostitution, dreaming, and loads more. Ekirch digs into all kinds of source material, not just literature and plays, but legal works, diaries, and medical accounts, giving a well-rounded view of how half the day was considered, used, and feared.
