ERATOSTHENES, (grek. Eratosthen'es),
Grekisk astronom (276-194 f.Kr.), född i Cyrene, av Ptolemaios III Euergetes kallad till bibliotekarie vid museet i Alexandria. E. utförde den första vetenskapliga bestämningen av jordens storlek. I Syene i Afrika kastade en gnomon vid sommarsolståndet icke någon skugga, då däremot vid samma tid solen i Alexandria var 7,2 grader (=360:50 grader) från zenit. Då avståndet mellan Syene och Alexandria enl. E. var 5.000 stadier, så följer, att jordens omkrets är = 50x5.000 = 250.000 stadier. Värdet på E:s stadie är ej säkert bekant, men följer man Plinius' uppgifter, är en stadie = 157,5 m, och i så afll blir alltså jordens omkrets = 39.375.000 m, nära överensstämmande med senare mätningar (40.000.000 m), en överensstämmelse, som dock kan betraktas som helt och hållet tillfällig.
Eratosthenes framställde även en världskarta.

A significant cartographic achievement, Van Verden's work on the Caspian led directly to Peter the Great's 1722 invasion of Baku and Derbent and Russian hegemony in the region. Despite his achievements in the Caspian, Van Verden was later passed up by the Tzar in favor of Vitus Behring for the commission to discover a Northeast Passage through the Russian Arctic.
Around 1718 the Russian Tzar, Peter the Great, sponsored a number of cartographic expeditions to the farthest reaches of his vast empire. Most of these were headed up by Dutch navigators, the most experienced and mercenary of the era. Carl Van Verden, a Dutch seaman, was commissioned as a Russian naval officer and assigned the task of mapping the Caspian Sea. Though we...
