This book is the fruit of the first ever interdisciplinary international scientific conference on Matthew's story of the Star of Bethlehem and the Magi, held in 2014 at the University of Groningen, and attended by world-leading specialists in all relevant fields: modern astronomy, the ancient near-eastern and Greco-Roman worlds, the history of science, and religion. The scholarly discussions and the exchange of the interdisciplinary views proved to be immensely fruitful and resulted in the present book. Its twenty chapters describe the various aspects of The Star: the history of its interpretation, ancient near-eastern astronomy and astrology and the Magi, astrology in the Greco-Roman and the Jewish worlds, and the early Christian world - at a generally accessible level. An epilogue summarizes the fact-fiction balance of the most famous star which has ever shone.

Until now, important research on the historical records of comets and meteor showers from China, Japan, and Korea has remained the exclusive preserve of those with expertise in the relevant languages. With a compilation like the present volume the authors hope to ameliorate that situation. Applying the same rigorous selection criteria and style of presentation as in the previous catalogue, assembled and translated here are some 1,500 additional observations of comets and meteor showers from China, Japan, and Korea spanning nearly three millennia. With the publication of this volume, most of the important historical records of East Asian astronomical observations are now accessible in English. The introductions and appendices provide all the required information on specialized terminology, recording conventions, and nomenclature the reader will need to make use of the records. In addition to being an invaluable resource for professional astronomers, East Asian astronomical records have materially aided the research of scholars in fields as diverse as mythology, medieval iconography, ancient chronology, and the oral history of pre-literate societies. The book should be of great interest to cultural astronomers, as well as to those engaged in historical and comparative research.

In the year 921/2, the Jewish leaders of Palestine and Babylonia disagreed on how to calculate the calendar. This led the Jews of the entire Near East to celebrate Passover and the other festivals, through two years, on different dates. The controversy was major, but it became forgotten until its late 19th-century rediscovery in the Cairo Genizah. Faulty editions of the texts, in the following decades, led to much misunderstanding about the nature, leadership, and aftermath of the controversy. In this book, Sacha Stern re-edits the texts completely, discovers many new Genizah sources, and challenges the historical consensus. This book sheds light on early medieval Rabbanite leadership and controversies, and on the processes that eventually led to the standardization of the medieval Jewish calendar.

Cosmology is the study of the origin, size, and evolution of the entire universe. Every culture has developed a cosmology, whether it be based on religious, philosophical, or scientific principles. In this book, the evolution of the scientific understanding of the Universe in Western tradition is traced from the early Greek philosophers to the most modern 21st century view. After a brief introduction to the concept of the scientific method, the first part of the book describes the way in which detailed observations of the Universe, first with the naked eye and later with increasingly complex modern instruments, ultimately led to the development of the "Big Bang" theory. The second part of the book traces the evolution of the Big Bang including the very recent observation that the expansion of the Universe is itself accelerating with time.
