Dear Gianni, I am interesting for the 'camera obscura' in Italy. Some Meridiana in the Church in Italy I habe seen. In Bologna, S. Petronia with Giovanni Paltrinieri.
I read your list (PDF) with the 74 meridiana (camera obscura) in the Internet. I have not the book about "XI Seminario di Gnomonica". You write for a PDF-File of 450 kB. Is there a better list contained ? Please send me this PDF-file (around 450 kB) for e-mail.
