Un modo breve & facili per far gl'horologii orizontali italiani per via di numeri [manuscript]
This is a manuscript treatise of 1700 on Italian horizontal sundials, attributed to Giovanni Girolamo Glinigh with Giovanni Francesco Palmieri named as a contributor, held by the Smithsonian Libraries and donated by Bern Dibner. The pages are handwritten in ink with hand-drawn geometric diagrams of sundial hour lines and a dial layout, showing the method as a working draft a designer could study for radiating line patterns.
