The Vatican Library is putting 4,000 (yes, four thousand!) manuscripts online. This is only a fraction of the 80,000 documents that the Vatican Library has collected since its inception in 1451. What an incredible resource for calligraphers!
The interface is good, providing views of each page with a great zoom range. This image comes from the manuscript book labeled “Arch.Cap.S.Pietro.A.3” in the collection “Archivio del Capitolo di San Pietro“. Codices in this collection come from the library of the Chapter of St. Peter Basilica.
I’ve spent hours already browsing through this wonderful resource.
