Sundials: History, Theory, and Practice - Unveiling the Secrets of Timekeeping

Have you ever wondered how our ancestors measured time before the invention of mechanical clocks? Enter the fascinating world of sundials – ancient timekeeping devices that allowed civilizations to synchronize their activities with the sun's movement across the sky. In this article, we explore the rich history, intricate theory, and practical use of sundials, shedding light on their mesmerizing legacy that continues to capture the imagination of people even today.

1. The Origins of Sundials

Sundials can be traced back to ancient Egypt, where the obelisk served as the earliest recorded sundial. The ancient Egyptians, known for their advanced astronomical knowledge, used the shadow cast by the obelisk to determine the time of day. From Egypt, the concept of sundials spread to other ancient civilizations like the Greeks and Romans, who further refined the design and accuracy of these timekeeping instruments.

2. The Theory behind Sundials

At its core, a sundial works based on the position of the sun and the shadows it casts. By understanding the Earth's rotation and the sun's movement, sundial enthusiasts can decipher the time with remarkable precision. Various mathematical and astronomical concepts come into play, such as the analemma, declination, and equation of time, all contributing to the accurate functioning of sundials across different locations on Earth.

"His lively pen, his direct and simple style, his expressive vocabulary, his avoidance of pedantry, his conciseness in the exposition of his thoughts make his book a pleasure to read." — Henri Michel, International Academy of the History of Science
The story of man's efforts to measure time is a long one — reaching back thousands of years to the dawn of civilization. Among the earliest instruments developed for telling time was the sundial. In this expert study, a noted sundial expert offers a fascinating and informative account of these ancient devices, presented in simple, lively language.
Over the centuries, many different varieties of sundials have been constructed, and Mr. Rohr provides detailed, accurate descriptions of them all: classical sundials, inclined dials, solar calendars, analemmatic dials, moon dials, and many more. There is even a chapter devoted to especially remarkable dials past and present, and a listing of the most popular sundial mottoes.
In this profusely illustrated volume, you will not only learn about the long and colorful history of the sundial, you will learn a practical method of building one yourself. No special knowledge is required, other than an understanding of the basic principles of cosmography and of the relative movements of the sun and the planets. (These are recalled in an elementary way in a special chapter.) For mathematically inclined readers, more complex formulae and calculations have been included, some of which have never been printed in a book of gnomonics.
