 | | Latitude was measured from the equator, as it is today, but Ptolemy preferred to express it as the length of the longest day rather than degrees of arc (the length of the midsummer day increases from 12h to 24h as you go from the equator to the polar circle). | | | A 15th century depiction of the Ptolemy world map, reconstituted from Ptolemy's Geographia (circa 150), indicating the countries of "Serica" and "Sinae" (China) at the extreme right, beyond the island of "Taprobane" (Sri Lanka, oversized) and the "Aurea Chersonesus" (Malay Peninsula). | | | The maps in surviving manuscripts of Ptolemy's Geographia, however, date only from about 1300, after the text was rediscovered by Maximus Planudes. |

| | Ptolemy's world map, reconstituted from Ptolemy's Geographia (circa 150), indicating "Sinae" (China) at the extreme right, beyond the island of "Taprobane" (Sri Lanka, oversized) and the "Aurea Chersonesus" (Southeast Asian peninsula). | | | The Ptolemy world map is a map based on the description of the world contained in Ptolemy's book Geographia, written circa 150 CE. | | | Although authentic maps have never been found, the Geographia contains thousands of references to various parts of the old world, with coordinates for most, which allowed cartographers to recontruct Ptolemy's world view when the manuscript were re-discovered around 1300 CE. |

| | In another book, the Planisphaerium, Ptolemy is concerned with stereographic projection--the delineation of the forms of solid bodies on a plane--and here he used the south celestial pole as his center of projection. | | | As a result of such arguments, the geocentric system became dogmatically asserted in Western Christendom until the 15th century, when it was supplanted by the heliocentric (Sun-centered) system of Nicolaus Copernicus (q.v.), a Polish astronomer. | | | Not least, he showed that if the Earth moved, as some earlier philosophers had suggested, then certain phenomena should in consequence be observed. |
