[La sfera]
This is a manuscript copy of La sfera, a didactic poem on cosmography and geography attributed to Gregorio Dati, here in a version by Leonardo Dati, written out by the scribe Gaspar de Fidelis in Pesaro. The first picture shows dense handwritten Italian verse in two columns with faint sketched diagrams in the margin, while the second shows a hand-drawn zodiac band labelled Aries, Taurus, Gemini, Cancer, Leo and Virgo, useful for designers studying ink-and-pen astronomical diagrams.
