Book Description

"Tetrabiblos" from Ptolemy. Greco-roman writer of Alexandria, known as a mathematician, astronomer, geographer, astrologer, and poet (90-168A.D.).




Ptolemy I


Book Description

When Rome defeated the forces of Antony and Cleopatra and annexed Egypt, the rule of the longest-lived of the Hellenistic dynasties and one of the most illustrious in Egyptian history came to an end. For nearly three hundred years, the Macedonian dynasty known as the Ptolemaic had controlled Egypt and its mixed population of Egyptians, Greeks, Macedonians, and Jews. The founder of this dynasty, Ptolemy I (367-283/2 BC), was a boyhood friend and eventually personal bodyguard of Alexander the Great, who fought alongside Alexander in the epic battles that toppled the Persian Empire, and brought about a Macedonian Empire stretching from Greece to India. After Alexander's death, his senior staff carved up his vast empire, with Ptolemy gaining control of Egypt. There he built up his power base in Egypt, introduced administrative and economic reforms that made his family fabulously wealthy, and by extending Egypt's possessions overseas founded an Egyptian Empire. In addition to his political and military prowess, Ptolemy was an intellectual, who patronized the mathematician Euclid, wrote an important account of Alexander's campaign in Asia, and established the famous Library and Museum at Alexandria, which were the cultural heart of the entire Hellenistic Age. Ptolemy ruled Egypt until he died of natural causes in his early eighties. Ian Worthington's Ptolemy I--the first full-length biography of its kind in English--traces the life of Ptolemy from his boyhood to his reign as king and pharaoh of Egypt. Throughout, he highlights the achievements that profoundly shaped both Egypt's history and that of the early Hellenistic world. He argues that Ptolemy was by far the greatest of Alexander's Successors, and that he was a conscious imperialist who even boldly attempted to seize Greece and Macedonia, and be a second Alexander.




Geography of Claudius Ptolemy


Book Description

Geography of Claudius Ptolemy, originally titled Geographia and written in the second century, is a depiction of the geography of the Roman Empire at the time. Though inaccurate due to Ptolemy's varying methods of measurement and use of outdated data, Geography of Claudius Ptolemy is nonetheless an excellent example of ancient geographical study and scientific method. This edition contains more than 40 maps and illustrations, reproduced based on Ptolemy's original manuscript. It remains a fascinating read for students of scientific history and Greek influence. CLAUDIUS PTOLEMY (A.D. 90- A.D. 168) was a poet, mathematician, astronomer, astrologer, and geographer who wrote in Greek, though he was a Roman citizen. He is most well-known for three scientific treatises he wrote on astronomy, astrology, and geography, respectively titled Almagest, Apotelesmatika, and Geographia. His work influenced early Islamic and European studies, which in turn influenced much of the modern world. Ptolemy died in Alexandria as a member of Greek society.




Ptolemy's Philosophy


Book Description

A stimulating intellectual history of Ptolemy's philosophy and his conception of a world in which mathematics reigns supreme The Greco-Roman mathematician Claudius Ptolemy is one of the most significant figures in the history of science. He is remembered today for his astronomy, but his philosophy is almost entirely lost to history. This groundbreaking book is the first to reconstruct Ptolemy’s general philosophical system—including his metaphysics, epistemology, and ethics—and to explore its relationship to astronomy, harmonics, element theory, astrology, cosmology, psychology, and theology. In this stimulating intellectual history, Jacqueline Feke uncovers references to a complex and sophisticated philosophical agenda scattered among Ptolemy’s technical studies in the physical and mathematical sciences. She shows how he developed a philosophy that was radical and even subversive, appropriating ideas and turning them against the very philosophers from whom he drew influence. Feke reveals how Ptolemy’s unique system is at once a critique of prevailing philosophical trends and a conception of the world in which mathematics reigns supreme. A compelling work of scholarship, Ptolemy’s Philosophy demonstrates how Ptolemy situated mathematics at the very foundation of all philosophy—theoretical and practical—and advanced the mathematical way of life as the true path to human perfection.




Ptolemy's Almagest


Book Description

Ptolemy's Almagest is one of the most influential scientific works in history. A masterpiece of technical exposition, it was the basic textbook of astronomy for more than a thousand years, and still is the main source for our knowledge of ancient astronomy. This translation, based on the standard Greek text of Heiberg, makes the work accessible to English readers in an intelligible and reliable form. It contains numerous corrections derived from medieval Arabic translations and extensive footnotes that take account of the great progress in understanding the work made in this century, due to the discovery of Babylonian records and other researches. It is designed to stand by itself as an interpretation of the original, but it will also be useful as an aid to reading the Greek text.




Ptolemy's Geography


Book Description

Ptolemy's Geography is the only book on cartography to have survived from the classical period and one of the most influential scientific works of all time. Written in the second century AD, for more than fifteen centuries it was the most detailed topography of Europe and Asia available and the best reference on how to gather data and draw maps. Ptolemy championed the use of astronomical observation and applied mathematics in determining geographical locations. But more importantly, he introduced the practice of writing down coordinates of latitude and longitude for every feature drawn on a world map, so that someone else possessing only the text of the Geography could reproduce Ptolemy's map at any time, in whole or in part, at any scale. Here Berggren and Jones render an exemplary translation of the Geography and provide a thorough introduction, which treats the historical and technical background of Ptolemy's work, the contents of the Geography, and the later history of the work.




Ptolemy of Egypt


Book Description

Ptolemy was the creator of the longest lasting of the Hellenistic kingdoms. He created a state whose cultural importance was unparalleled until the coming of Rome. He encouraged the erection of the Pharos Lighthouse, one of the seven wonders of the ancient world, as well as creating a library which eventually contained the greatest collection of books until relatively recent times. Ptolemy's institution of higher learning, the Museum, gave birth to the greatest advancements in science before the seventeenth century of our own era. In this work, the first biography of Ptolemy in any language, Professor Ellis charts Ptolemy's extraordinary achievements in and beyond Egypt in the context of the fragmentation of Alexander's enormous empire and the creation of the Hellenistic state.







The Almagest


Book Description

The Almagest is by far the greatest work in astronomy in ancient times. In a massive series of thirteen books, Ptolemy shows how every detail of the motions of the sun, moon, planets, and stars can be expressed using geometrical models that can be used to compute celestial positions with remarkable accuracy The present selection covers all the essential features of Ptolemy s treatment of the heavens, omitting only more difficult and abstruse matters such as the moon s motion and the calculation of eclipses. In the interest of conciseness, development of planetary theories is restricted to two planets, one inferior (Venus) and one superior (Mars). Ptolemy s text is accompanied by extensive notes and introductions that are aimed at making the book accessible to students encountering Ptolemy for the first time. This edition is designed to provide everything needed for a one-semester course, or it can be a component of a more general course on planetary theory or history of astronomy."
