Visited the Monastery at San Lorenzo de El Escorial, a short walk from where I'm currently staying. Which means I got to see the Book of Chess, Dice and Board Games by Alfonso X The Wise. A fascinating historical tome of interest to #BoardGames people and #BGDev #GameDev folkes.
Fav illustration from Libro de los juegos is where chess are played together with playing harp. :)

Alfonso X was also a great composer, having "Santa Maria strela do Dia" as maybe the biggest hit...
