This investigation is concerned with ancient Egyptian calendars. Its specific focus is one of the oldest problems of the study of these calendars: the so-called problem of the month names. This work's main purpose is to suggest an explanation for the Brugsch phenomenon. The Brugsch phenomenon is one of the two main aspects of the problem of the month names. The other is the Gardiner phenomenon. No new theory is presented for the Gardiner phenomenon. As a problem, the Brugsch phenomenon is slightly older than the Gardiner Phenomenon. It has occupied center stage in the study of ancient Egyptian calendars since the early days of this endeavor. In 1870, Heinrich Brugsch, the great pioneer in this subject, wrote about the phenomenon, "Here we encounter all at once the most curious contradiction." Just recently, Rolf Krauss has described the contradiction as still "unsolved". The Brugsch phenomenon concerns the indisputable fact that the last or twelfth month of the Egyptian civil year can be named as if it were the first. Two month names are involved. The first is wp rnpt. Its meaning "opener of the year," refers to a beginning. The second month name is mswt r' "birth of Re" in hieroglyphic Egyptian, Mesore in Aramaic, Greek and Coptic. Both can otherwise also refer to New Year's Day, the quintessential calendrical beginning.

Dates form the backbone of written history. But where do these dates come from? Many different calendars were used in the ancient world. Some of these calendars were based upon observations or calculations of regular astronomical phenomena, such as the first sighting of the new moon crescent that defined the beginning of the month in many calendars, while others incorporated schematic simplifications of these phenomena, such as the 360-day year used in early Mesopotamian administrative practices in order to simplify accounting procedures. Historians frequently use handbooks and tables for converting dates in ancient calendars into the familiar BC/AD calendar that we use today. But very few historians understand how these tables have come about, or what assumptions have been made in their construction. The seven papers in this volume provide an answer to the question what do we know about the operation of calendars in the ancient world, and just as importantly how do we know it? Topics covered include the ancient and modern history of the Egyptian 365-day calendar, astronomical and administrative calendars in ancient Mesopotamia, and the development of astronomical calendars in ancient Greece. This book will be of interest to ancient historians, historians of science, astronomers who use early astronomical records, and anyone with an interest in calendars and their development.

This series provides a history of time and our gradual comprehension, measuring and recording of different types of time. This text looks at calendars. It emphasises science and history with key dates boxes and spreads that act as mini timelines and is suitable for school projects.

This is volume one of a two-volume study of a war and moon god religion that was based on the Mideast moon god religion of Sin.

Calendars were at the heart of ancient culture and society and were far more than just technical, time-keeping devices. Calendars in Antiquity offers a comprehensive study of the calendars of the ancient Mediterranean and Near Eastern world, from the origins up to and including Jewish and Christian calendars in late Antiquity.

This first of three volumes starts with a short introduction to historical metrology as a scientific discipline and goes on with an anthology of acient and modern measurement systems of all kind, scientific measures, units of time, weights, currencies etc. It concludes with an exhaustive list of references. Units of measurement are of vital importance in every civilization through history. Since the early ages, man has through necessity devised various measures to assist him in everyday life. They have enabled and continue to enable us to trade in commonly and equitably understood amounts, and to investigate, understand, and control the chemical, physical, and biological processes of the natural world. The essence of the work is an alphabetically ordered, comprehensive list of measurement nomenclature, units and scales. It provides an understanding of almost all quantitative expressions observed in all imaginable situations, including spelling variants and the abbreviations and symbols for units, and various acronyms used in metrology. It will be of use not only to historians of science and technology, but also to economic and social historians and should be in every major academic and national library as standard reference work on the topic.

To understand modern science as a coherent story, it is essential to recognize the accomplishments of the ancient Hindus. They invented our base-ten number system and zero that are now used globally, carefully mapped the sky and assigned motion to the Earth in their astronomy, developed a sophisticated system of medicine with its mind-body approach known as Ayurveda, mastered metallurgical methods of extraction and purification of metals, including the so-called Damascus blade and the Iron Pillar of New Delhi, and developed the science of self-improvement that is popularly known as yoga. Their scientific contributions made impact on noted scholars globally: Aristotle, Megasthenes, and Apollonius of Tyana among the Greeks; Al-Biruni, Al-Khwarizmi, Ibn Labban, and Al-Uqlidisi, Al-Ja?iz among the Islamic scholars; Fa-Hien, Hiuen Tsang, and I-tsing among the Chinese; and Leonardo Fibbonacci, Pope Sylvester II, Roger Bacon, Voltaire and Copernicus from Europe. In the modern era, thinkers and scientists as diverse as Ralph Waldo Emerson, Johann Wolfgang von Goethe, Johann Gottfried Herder, Carl Jung, Max Müller, Robert Oppenheimer, Erwin Schrödinger, Arthur Schopenhauer, and Henry David Thoreau have acknowledged their debt to ancient Hindu achievements in science, technology, and philosophy. The American Association for the Advancement of Science (AAAS), one of the largest scientific organizations in the world, in 2000, published a timeline of 100 most important scientific finding in history to celebrate the new millennium. There were only two mentions from the non-Western world: (1) invention of zero and (2) the Hindu and Mayan skywatchers astronomical observations for agricultural and religious purposes. Both findings involved the works of the ancient Hindus. The Ancient Hindu Science is well documented with remarkable objectivity, proper citations, and a substantial bibliography. It highlights the achievements of this remarkable civilization through painstaking research of historical and scientific sources. The style of writing is lucid and elegant, making the book easy to read. This book is the perfect text for all students and others interested in the developments of science throughout history and among the ancient Hindus, in particular.
