Made the most of a spare hour over lunchtime between meetings in Oxford to pay a visit to the wonderful Oxford University Museum of Natural History. I usually get drawn into the murky depths of the Pitt Rivers Museum at the back, but the sun was streaming in, making the stonework relief carvings on the first floor look even more impressive than usual. I also spotted this photograph on the stairs showing masons (from Farmer & Brindley) working on the same carvings in around 1911. Gratifying to think their hard work is still being admired more than a century later.
