Back in Cordoba, this time inside the Mezquita. The first sketch is an attempt to describe the famous forest of columns, mostly inhabited by tourists; as the columns recede in all directions it feels slightly like being in an Escher drawing or a hall of mirrors. Then there’s a collection of carved stone faces on a tomb. And finally some very fast drawings of visitors photographing the lofty nave (incongruously inserted into the mosque in the C16th); they’d walk in, point a device, shoot, and leave, all in about 30 seconds, job done!
