A nocturnal in use, from the the 1524 edition of Cosmographia
Cosmographia . . . is about the world, which consists of four elements: earth, water, air, and fire
Thus writes Petrus Apianus in the opening lines of Cosmographicus liber a Petro Apiano mathematico studiose collectus, more commonly known as Cosmographia. The nod to the four classical elements is a fitting introduction to a delightful, wide-ranging work that was partly a rehash of medieval scientific thought and partly a paean to Renaissance ingenuity and the burgeoning spirit of discovery.
