Today we spent over three hours in the Escher Museum in The Hague--an extremely intriguing and engrossing experence. It is devoted solely to the work and life of M.C. Escher (1898-1972), a Dutch graphic artist whose works were inspired by mathematical concepts. The rooms contain fifteen glass chandeliers designed by the Dutch artist Hans van Bentem, which relate to Escher's works. This blip shows a star-shaped one in the ballroom of the palace housing the museum, which was occupied for several decades by Queen Emma of the Netherlands. I had always found Escher interesting, but today, I was greatly struck by the extent to which some of my photographs echo certain of his interests. A startling example is this reflecting puddle of mine--compare it with Escher's "Puddle". In the late afternoon we went to the Mauritshuis --another wonderful museum, as we had done in 2015 (see the link).
