An Italian documentary about the Dutch artist made in 1980 and directed by Michele Emmer. I don’t recall ever seeing a British TV documentary about Escher (although I’d be surprised if there were none) but this resembles the type of thing the BBC used to do so well. Shots of the Italian towns where Escher lived for many years show the influence of the vernacular architecture on Escher’s prints. Elsewhere, animated sequences bring to life his tessellations, while various mathematicians examine some of the structural principles at work in these very familiar images. Of greatest interest for me is mathematician and physicist Roger Penrose discussing his first encounter with Escher’s work, and the development with his father of the Penrose Triangle, an impossible object similar to those that appear in some of Escher’s prints. (I used a Penrose Triangle in my cover art for Zones by Hawkwind.) The Fantastic World of MC Escher runs for 50 minutes, and may be watched here.
