This book is intended for geophysicists, astronomers (especially those with an interest in history), historians and orientalists. The culmination of many years of research, it discusses, in depth, ancient and medieval eclipse observations and their importance in studying Earth's past rotation. This was the first major book on this subject to appear in the last twenty years. The author has specialised in the interpretation of early astronomical records and their application to problems in modern astronomy for many years. The book contains an in-depth discussion of numerous eclipse records from Babylon, China, Europe and the Arab lands. Translations of almost every record studied are given. It is shown that although tides play a dominant long-term role in producing variations in Earth's rate of rotation - causing a gradual increase in the length of the day - there are significant, and variable non-tidal changes in opposition to the main trend.

This book contains papers from a conference held to celebrate the 70th birthday of one of the world’s foremost astronomical historians, Professor F. Richard Stephenson, the latest recipient of the American Astronomical Society’s highest award for research in astronomical history, the LeRoy Doggett Prize. Reflecting Professor Stephenson’s extensive research portfolio, this book brings together under one cover papers on four different areas of scholarship: applied historical astronomy (which Stephenson founded); Islamic astronomy; Oriental astronomy and amateur astronomy. These papers are penned by astronomers from Canada, China, England, France, Georgia, Iran, Japan, Lebanon, the Netherlands, Portugal, Thailand and the USA. Its diverse coverage represents a wide cross-section of the history of astronomy community. Under discussion are ways in which recent research using historical data has provided new insights into auroral and solar activity, supernovae and changes in the rotation rate of the Earth. It also presents readers with results of recent research on leading historical figures in Islamic and Oriental astronomy, and aspects of eighteenth and nineteenth century Australian, British, German and Portuguese amateur astronomy, including the fascinating ‘amateur-turned-professional syndrome’.

They have been thought of as harbingers of evil as well as a sign of the divine. Eclipses—one of the rarest and most stunning celestial events we can witness here on Earth—have shaped the course of human history and thought since humans first turned their eyes to the sky. What do Virginia Woolf, the rotation of hurricanes, Babylonian kings and Einstein’s General Theory Relativity all have in common? Eclipses. Always spectacular and, today, precisely predicable, eclipses have allowed us to know when the first Olympic games were played and, long before the first space probe, that the Moon was covered by dust. Eclipses have stunned, frightened, emboldened and mesmerized people for thousands of years. They were recorded on ancient turtle shells discovered in the Wastes of Yin in China, on clay tablets from Mesopotamia and on the Mayan “Dresden Codex." They are mentioned in Homer’s Iliad and Odyssey and at least eight times in the Bible. Columbus used them to trick people, while Renaissance painter Taddeo Gaddi was blinded by one. Sorcery was banished within the Catholic Church after astrologers used an eclipse to predict a pope’s death. In Mask of the Sun, acclaimed writer John Dvorak the importance of the number 177 and why the ancient Romans thought it was bad to have sexual intercourse during an eclipse (whereas other cultures thought it would be good luck). Even today, pregnant women in Mexico wear safety pins on their underwear during an eclipse. Eclipses are an amazing phenomena—unique to Earth—that have provided the key to much of what we now know and understand about the sun, our moon, gravity, and the workings of the universe. Both entertaining and authoritative, Mask of the Sun reveals the humanism behind the science of both lunar and solar eclipses. With insightful detail and vividly accessible prose, Dvorak provides explanations as to how and why eclipses occur—as well as insight into the forthcoming eclipse of 2017 that will be visible across North America.

The Sun is nowadays observed using di?erent techniques that provide an almost instantaneous 3-D map of its structure. Of particular interest is the studyofthevariabilityinthesolaroutputproducedbythedissipationofm- netic energy on di?erent spatial and temporal scales – the so-called magnetic activity. The 11-year cycle is the main feature describing this phenomenon. Apart from its intrinsic scienti?c interest, this topic is worth studying because of the interaction of such processes with the terrestrial environment. A ?eet of space and ground-based observatories are currently monitoring the behaviour of our star on a daily basis. However, solar activity varies not only on this decadal time-scale, as has been attested mainly through two methods: (a) records of the number of sunspots observed on the solar surface from 1610, and (b) the records of 14 10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and i- cores, respectively. The study of the long-term behaviour of solar activity may be comp- mented by the study of historical accounts describing phenomena directly or indirectly related to solar activity. Numerous scienti?c and non-scienti?c d- uments have reported these events and we can make use of them as a proxy of solar activity in past times.
