Italian Renaissance art - from F to Z

[smo]

There was a landscape/architectural painter during the Italian Renaissance period - think Bruneschelli and the Duomo in Florence- (or possibly later) who specialized in drawings/sketchings of building plans that were too extravagant to realize but nevertheless attracted audiences due to their fantastical shapes/visions (terraces,bridges,towers,moats, etc.) He's semi-famous to the point that there are books written about him. I was at one point in the process of checking some of those books on eBay circa 15, 20 years ago. The only thing Google comes up now is Piranesi, but that's not him - my guy's name begins with "F" or "Fr" (but nof Fragonard, he's French). Google couldn't help me with that. Any Thaivisa member here can? Thanks
