The April 1998 (Vol 14 #1) issue of "The Pinhole Journal" is titled "A Tour of Renaissance Pinhole Sites in Italy. In addition to places related to art and perspective, they also visited places with noon marks, meridian lines and reflected sundials. Information about the Pinhole Journal is available at http://www.pinholeresource.com/. Note, I do not own a copy of this journal, I saw it at the library of the Photographic Resource Society in Boston this weekend.
