    Eratosthenes was a man of many perspectives and investigated the art of poetry under Callimachus. [9] He wrote poems: one in hexameters called Hermes, illustrating the god's life history; and another in elegiacs, called Erigone, describing the suicide of the Athenian maiden Erigone (daughter of Icarius).

    Furthermore, the fact that Eratosthenes's measure corresponds precisely to 252,000 stadia might be intentional, since it is a number that can be divided by all natural numbers from 1 to 10: some historians believe that Eratosthenes changed from the 250,000 value written by Cleomedes to this new value to simplify calculations; [27] other ...

  4. History of geography - Wikipedia

    en.wikipedia.org/wiki/History_of_geography

    In more recent developments, geography has become a distinct academic discipline. 'Geography' derives from the Greek γεωγραφία – geographia, [1] literally "Earth-writing", that is, description or writing about the Earth. The first person to use the word geography was Eratosthenes (276–194 BC).

  5. Geography - Wikipedia

    en.wikipedia.org/wiki/Geography

    Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. [2]

    Furthermore, the fact that Eratosthenes' measure corresponds precisely to 252,000 stadia (according to Pliny) might be intentional, since it is a number that can be divided by all natural numbers from 1 to 10: some historians believe that Eratosthenes changed from the 250,000 value written by Cleomedes to this new value to simplify calculations ...

  7. Early world maps - Wikipedia

    The captions demonstrate clearly the multiple functions of these large medieval maps, conveying a mass of information on Biblical subjects and general history, in addition to geography. Jerusalem is drawn at the centre of the circle, east is on top, showing the Garden of Eden in a circle at the edge of the world (1).

  8. History of longitude - Wikipedia

    en.wikipedia.org/wiki/History_of_longitude

    Eratosthenes in the 3rd century BC first proposed a system of latitude and longitude for a map of the world. His prime meridian (line of longitude) passed through Alexandria and Rhodes, while his parallels (lines of latitude) were not regularly spaced, but passed through known locations, often at the expense of being straight lines. [1]

  9. Arc measurement - Wikipedia

    en.wikipedia.org/wiki/Arc_measurement

    Arc measurement of Eratosthenes. Arc measurement, [1] sometimes called degree measurement [2] (German: Gradmessung), [3] is the astrogeodetic technique of determining the radius of Earth and, by extension, its circumference.
