Resurrecting the Analemma

Samuel G. Shaw

Abstract: The analemma is a figure eight shaped graphic representation of the earth's annual path around the sun. It provides the user with values of declination and equation of time for every day of the year. In the first half of the twentieth century, it was a standard feature on any globe or map of the world. In recent years, however, the analemma has all but disappeared. This paper resurrects the analemma. The construction and use of the analemma is explained and some modern source materials are provided. Using the analemma in conjunction with other low-tech methods, a complete scheme for navigating by the sun is outlined.
