This is a flint handaxe, reckoned to be 300,000 years old, discovered during the construction of the Regent Palace Hotel in 1912, in Glasshouse Street, Picadilly. The site advertises the opening of a new gallery, London before London, which I really must go and see when I’m next in the area. Maybe I’ll have the asking price for this book: The Prehistory and Topography of Southwark and Lambeth – I’ve been searching (in vain) for a topographical map of the London area for a long time, and this appears promise a small part of it… I’d rather have Edward O. Gordon’s Prehistoric London, its mounds and circles, but it’s long out of print, can’t put it on the wishlist, being a secondhand item…
