Giovanni Piranesi is one of my favorite artists. He is surely one of the most skillful renderers of architectural form ever. Which wouldn't be so exciting if he didn't then use his talent to create some of the most breathtaking and absurdly scaled scenes ever seen.

the only Piranesi stuff I've found on the web, and its soo slow

so instead I recommend the book "Piranesi: The Imaginary Views" published by Harmony Books

If you have come in the back door of Erik Johnson's Virtual Gallery via a net search, I suggest you try the front door...
