تحرير The أطلس Portal An atlas is a collection of maps, traditionally bound into book form, but now found in multimedia formats. As well as geographic features and political boundaries, many often feature geopolitical, social, religious and economic statistics. The first book that could be called an atlas was constructed from the calculations of Claudius Ptolemy, a Greek geographer working in Alexandria circa A.D. 150. The first edition was published in Bologna in 1477 and was illustrated with a set of 27 maps, though scholars say that it is not known whether the printed maps were engraved versions of original maps made by Ptolemy, or whether they were constructed by medieval Greek scholars from Ptolemy's text. The origin of the term atlas is a common source of misconception, perhaps because two different mythical figures named 'Atlas' are associated with mapmaking. King Atlas, a mythical King of Mauretania, was, according to legend, a wise philosopher, mathematician and astronomer who supposedly made the first celestial globe. However, the more widely known Atlas is a figure from Greek mythology. More about Atlases... edit    {{{title}}} edit    {{{title}}} The Geographia is Ptolemy's main work besides the Almagest. It is a compilation of what was known about the world's geography in the Roman Empire of the 2nd century. Ptolemy relied mainly on the work of an earlier geographer, Marinos of Tyre, and on gazetteers of the Roman and ancient Persian empire, but most of his sources beyond the perimeter of the Empire were unreliable. Ptolemy also devised and provided instructions on how to create maps both of the whole inhabited world (oikoumenè) and of the Roman provinces. In the second part of the Geographia he provided the necessary topographic lists, and captions for the maps. His oikoumenè spanned 180 degrees of longitude from the Canary islands in the Atlantic Ocean to China, and about 80 degrees of latitude from the Arctic to the East Indies and deep into Africa; Ptolemy was well aware that he knew about only a quarter of the globe. تحرير Related portals edit    {{{title}}} تحرير Related WikiProjects edit    {{{title}}} تحرير Topics تحرير Things you can do تحرير Related categories تحرير Associated Wikimedia البوابات الرئيسية: الثقافة | الأعلام و التراجم | الجغرافيا | التاريخ | الرياضيات | العلوم | المجتمع | التقنيات | الفلسفة | الأديان قارات: آسيا | إفريقيا | اوروبا | الأمريكيتين دول عربية: الجزائر | المغرب | المملكة العربية السعودية | تونس | ليبيا | فلسطين | مصر | [ بوابة المجتمع ] [ تصفح البوابات ]
