Download Eratosthenes' "Geography" Book in PDF, ePub and Kindle
This is the first modern edition and first English translation of one of the earliest and most important works in the history of geography, the third-century Geographika of Eratosthenes. In this work, which for the first time described the geography of the entire inhabited world as it was then known, Eratosthenes of Kyrene (ca. 285-205 BC) invented the discipline of geography as we understand it. A polymath who served as librarian at Alexandria and tutor to the future King Ptolemy IV, Eratosthenes created the terminology of geography, probably including the word geographia itself. Building on his previous work, in which he determined the size and shape of the earth, Eratosthenes in the Geographika created a grid of parallels and meridians that linked together every place in the world: for the first time one could figure out the relationship and distance between remote localities, such as northwest Africa and the Caspian Sea. The Geographika also identified some four hundred places, more than ever before, from Thoule (probably Iceland) to Taprobane (Sri Lanka), and from well down the coast of Africa to Central Asia. This is the first collation of the more than 150 fragments of the Geographika in more than a century. Each fragment is accompanied by an English translation, a summary, and commentary. Duane W. Roller provides a rich background, including a history of the text and its reception, a biography of Eratosthenes, and a comprehensive account of ancient Greek geographical thought and of Eratosthenes' pioneering contribution to it. This edition also includes maps that show all of the known places named in the Geographika, appendixes, a bibliography, and indexes.

Download The Library of the Unwritten Book in PDF, ePub and Kindle
In the first book in a brilliant new fantasy series, books that aren't finished by their authors reside in the Library of the Unwritten in Hell, and it is up to the Librarian to track down any restless characters who emerge from those unfinished stories. Many years ago, Claire was named Head Librarian of the Unwritten Wing-- a neutral space in Hell where all the stories unfinished by their authors reside. Her job consists mainly of repairing and organizing books, but also of keeping an eye on restless stories that risk materializing as characters and escaping the library. When a Hero escapes from his book and goes in search of his author, Claire must track and capture him with the help of former muse and current assistant Brevity and nervous demon courier Leto. But what should have been a simple retrieval goes horrifyingly wrong when the terrifyingly angelic Ramiel attacks them, convinced that they hold the Devil's Bible. The text of the Devil's Bible is a powerful weapon in the power struggle between Heaven and Hell, so it falls to the librarians to find a book with the power to reshape the boundaries between Heaven, Hell….and Earth.

Download Recentering the Universe Book in PDF, ePub and Kindle
In the sixth century B.C.E., the Greek philosopher Anaximander theorized that Earth was at the center of the cosmos. That idea became ingrained in scientific thinking and Christian religious beliefs for more than one thousand years. Defiance of church doctrine could mean death, so no one dared dispute this long-accepted idea. No one except a handful of courageous scientists. In the 1500s and 1600s, men like Nicolaus Copernicus, Johanned Kepler, Galileo Galilei, and Isaac Newton began to ask questions. What if Earth actually orbited the sun, instead of the other way around? What if the universe was much bigger than anyone imagined? These scientists risked their reputations—even their lives—to challenge the very heart of Catholic dogma and scientific tradition. Yet, in less than 200 years, their radical thinking overturned theories that had lasted more than a millennium. Join these bold thinkers on the journey of discovery that forever changed our understanding of the cosmos.
