It seems that, rather than producing a manual appended to a specific pair of his own globes, Senex published the present work as a general accompaniment to all globes. On the first page of the text, he states that “by the globes we here mean two artificial spherical bodies, whose convex part is supposed to give a true and exact representation of the Earth and Heavens, as visible by observation: and therefore are call’d the Terrestrial and Caelestial Globes”. The first section of the work is taken up with an explanation of each part of the globe, and each position it can be set in for different purposes. He then moves on to a series of 42 problems, which equip the reader with all the methods needed to use a pair of globes to tell the time of day, the latitude of a location and the movements of the constellations. Following his treatise on globes, Senex includes “A Geographical Description of the World”, including a description of Asia, Europe, America and Africa, along with some information about the size, peoples and cultures of certain countries within them.
The present work is extremely rare, with only 13 institutional examples worldwide, and no others on the market.
