Histories of the Unexpected
I haven't heard it myself, but I can see that Histories of the Unexpected has the perfect format for a podcast. Sam Willis and James Daybell take an everyday object (the moustache, scars, clouds, chimneys) and track its evolution, appearance across different cultures, or strange moments in time, to create a quirky but informative chapter, which always links to the next subject.
For instance, the chapter on Holes starts with a racy story of sixteenth century fornication observed through a hole in the wall; explores the history of priest holes built to shelter Elizabethan priests in recusant Catholic households; discusses other hiding places in walls now being discovered by modern laser scanners; mentions treasure hoards hidden in holes in the ground; talks about how objects can be lost from holes in pockets and later found by archaeologists; laments the damage caused by bookworms chewing holes in paper; and finishes up with holes in linen being mended by the unfortunate inmates of Magdalene Laundries... which links to the next chapter, the history of beds.
Broken up into easily digestible tidbits, this is a great book for browsing. I ended up reading a chapter a day. Overall, it's too thick a book to consume in one go, but it's clearly not designed for that. Like a podcast, best swallowed one tasty bite at a time.
