A Prognostication ... rules to iudge the weather

This illustration was taken from a small volume of predictions of the weather. The book was a best-seller of its time written by Leonard Digges (c.1515-1559), a well-known Elizabethan mathematician. Like contemporary almanacs it is an 'astro-meteorology' using zodiacal signs to predict the weather. More scientifically, the author includes tables of calculations, astronomical paper instruments and a perpetual calendar. He also gives clues to deduce the weather from observations at sunrise and sunset. This edition was revised by Thomas Digges (1546-1595), his son, who included one of the earliest published defense of Copernicus in England.
