When I was a teenager, prowling voraciously round my parents’ bookshelves looking for something to read, I found a row of old books that hadn’t been looked at for at least fifty years. They were all by Sabine Baring-Gould, polymath, squarson, folksong collector, novelist and possessor of an infectiously insatiable curiosity about pretty well everything from esoteric customs to ways in which to save fuel. Among those dusty Baring-Goulds were novels such as The Broom Squire and Mehalah, his Reminiscences of a ninety-year life, The Book of Werewolves, several collections of sermons, English Folk Songs (compiled with Cecil Sharp), Curious Myths of the Middle Ages and lots of travel books including Cliff Castles and Cave Dwellings in Europe, guides to the Riviera and the Languedoc, and Yorkshire Oddities and Strange Events. Best of all was Iceland, Its Scenes and Sagas.
