Lettera del dottor Donato Rossetti al signor dottor Carlo Fracassati
This is a 1668 Florentine letter in Italian by physician Donato Rossetti to Carlo Fracassati, filed under early physics and printed by the sign of the star. The single picture is a geometric diagram of a sector with lettered points, arcs and straight construction lines printed in black on the page. A designer might take from it the plain, labelled technical drawing style of seventeenth-century scientific print, where letters mark points and thin lines show construction.
