For the moment, Amazon.co.uk seems to be selling the e-book of The Masked City at the reduced price of £1.19. I don’t know why, and I have no idea of how long it’ll last, but if you were thinking of picking it up cheap, and you’re on UK amazon, well…
And also, here’s a truly spectacular animation of Piranesi’s Carceri prints which a friend of mine found.
To quote the background information:
…one of the key elements of the exhibition Le Arti di Piranesi: architetto, incisore, antiquario, vedutista, designer (The Art of Piranesi: architect, engraver, antiquarian, vedutista, designer), a 12 minute animation of Piranesi’s Carceri series made by Gregoire Dupond at Factum Arte specifically for the exhibition. This series of 16 visionary images, originally etched by Piranesi when in his late 20’s, shows the workings of his imagination, merging his architectural ambitions with his obsessive interest in antiquity. Watching Gregoire Dupond’s animation is literally like entering Piranesi’s mind.
