The only small, popular book on the important subject of ancient calendars.
The study of heavenly cycles is common to most ancient cultures. The ancient Egyptians, Chinese, and Babylonians all tried to make sense of the year. But it fell to the later Mesoamerican Maya to create a series of calendars that could be cross referenced. In doing so, the Maya discovered many strange numerical harmonics. Their lunar calendar was extremely accurate--far more so than the Greek Metonic cycle; they tracked Venus to an accuracy of less than a day in five hundred years and their tables could have been used to predict eclipses seven hundred years in the future. This book will provide a much needed compact guide to the Mayan calendar systems as well as covering the essentials of calendar development throughout the world.

Removes the scanning artefacts and transmission imperfections to produce a most comprehensive and beautifully detailed set of images of the lunar surface.

To help practical astronomers, all the photographs are systematically related to an Earth-based view.

Organized to make it easy for astronomers to use, enabling ground-based images and views to be compared with the Orbiter photographs.

A CD is included, providing the enhanced and cleaned photographs for screen viewing, lectures, etc..

The Photographic Atlas of the Stars contains 50, high-quality full color photographs of the entire night sky of the northern and southern hemispheres. Each plate is accompanied by a star map of the identical area, which identifies the main stars of the constituent constellations as well as other interesting astronomical objects. In addition to this detail, Sir Patrick Moore has written a commentary for each plate that highlights the stars and objects of interest to observers equipped with binoculars and that includes detailed tabular information on astronomical objects of the region. The resulting double-page spread provides an invaluable reference for the amateur astronomer, detailing the constellations and other heavenly bodies of interest that are observable with the naked eye, binoculars, or a small telescope.

Despite a resurgence in popularity, horoscopes are generally considered to be pseudoscience today - but they were once a cutting-edge scientific tool. In this ingenious work of history, data scientist Alexander Boxer examines a treasure trove of esoteric classical sources to expose the deep imaginative framework by which - for millennia - we made sense of our fates. Astrology, he argues, was the ancient world's most ambitious applied mathematics problem, a grand data-analysis enterprise sustained by some of history's most brilliant minds, from Ptolemy to al-Kindi to Kepler. A Scheme of Heaven explores the wonderful subtleties of astrological ideas. Telling the stories of their inventors and most influential exponents, Boxer puts them through their paces using modern data sets - finding that the methods of today's scientists are often uncomfortably close to those of astrology's ancient sages.

As interest in astrology continues to grow, so too have the sales of this accurate working tool. Every astrologer preparing accurate birth charts needs the information in this book. It is widely recognised in its classic livery and for its proven record of reliability and accuracy. Raphael's Ephemeris should be displayed in every astrology outlet, general bookshop and mind, body, spirit outlet for maximum sales. It contains daily longitudes of all the planets, tables of houses for London, Liverpool and New York, plus a complete lunar and planetary aspectarian.

This annual publication gives the longitudes of all planets for each day and their latitudes and declinations for every other day. This most accurate and comprehensive Ephemeris published is a necessary aid to casting horoscopes.'

Volume 2 of the four-volume catalog of comets observed throughout history provides a complete summary of every comet seen during the nineteenth century. It includes details of discovery, closest approaches to the Sun and Earth, path across the sky, physical descriptions, orbital information, and final observations. The catalog provides amateur and professional astronomers, and historians of science, with a definitive reference on comets through the ages. Also available: Volume 1: Ancient-1799 1999 0-521-58504-X $95.00 C

Cometography is the most complete and comprehensive collection of data on comets available. It comes in four self-contained sequential volumes and this, the first, covers ancient times through to the end of the eighteenth century. Cometography uses the most reliable orbits known to determine all the key parameters of each well observed comet. Cometography also provides nontechnical details to help the reader understand how the comet may have influenced various cultures at the time of its appearance. All the information in Cometography has been sourced directly from the original documents, including European monastic histories, Roman, Greek and Muslim texts, Chinese, Japanese and Korean scripts. In many cases, dates of important historical events can be corrected based on the appearance of a comet and identified using this book. Cometography will be valuable to historians of science as well as providing amateur and professional astronomers with a definitive reference on comets through the ages.

The introduction of the moving sphere as a model for understanding the celestial phenomena caused a great breakthrough in scientific thinking about the structure of the world. It provided the momentum for making celestial globes and mapping the stars. Celestial globes were produced first by Greek astronomers, and soon became greatly appreciated in antiquity as decorative objects (3 antique globes). The design and construction of the globe varied greatly as it passed through the Arabic (10 scientific globes made before 1500) and Medieval European cultures (3 scientific globes made before 1500). It was the starting-point for the design of many maps in antiquity and later in the Middle Ages (33) serving to illustrate books such as Aratus's Phaenomena. In the early fifteenth century scientific celestial maps (5) were constructed in their own right, independent of globes. In this book all extant celestial maps and globes made before 1500 are described and analysed in detail. This prestigious study will appeal to academic historians of science and astronomy, and art historians alike.

As interest in astrology continues to grow, so too have the sales of this accurate working tool. Raphael's Ephemeris continues to fill the astrologer's everyday need for pocket reference and is used extensively by professionals and students alike. The Ephemeris is widely recognised in its classic livery and should be displayed by general bookshops, specialised New Age shops and, of course, in every astrology outlet. Longitudes of all the planets for every day of the year. Tables of Houses for London, Liverpool and New York. Complete Lunar and Planetary Aspectarian together with all the necessary data for casting horoscopes North and South of the Equator.

Raphael's Astronomical Ephemeris has been published every year for well over 100 years. Renowned for its accuracy, it is respected the world over as the number one portable planetary guide and aspectarian.

Modern telescopes of even modest aperture can show thousands of double stars. Many are faint and unremarkable but hundreds are worth searching out. Veteran double-star observer Bob Argyle and his co-authors take a close-up look at their selection of 175 of the night sky's most interesting double and multiple stars. The history of each system is laid out from the original discovery to what we know at the present time about the stars. Wide-field finder charts are presented for each system along with plots of the apparent orbits and predicted future positions for the orbital systems. Recent measurements of each system are included which will help you to decide whether they can be seen in your telescope, as well as giving advice on the aperture needed. Double star observers of all levels of experience will treasure the level of detail in this guide to these jewels of the night sky.
