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.

Not much is known of Vooght's personal life beyond his own description of himself as a 'surveyor and teacher of mathematics and the art of navigation' on which he was a prolific writer. He is noted as the author of charts in Johannes van Keulen's Zee-Fakkel; indeed, on some editions only his name appears and in consequence the Zee-Fakkel is often catalogued under his name.

GERRITSZ [GERARD, GERARDUS, GHERRITSZOON van ASSUM].
Biografiska uppgifter:Hessel 1581-1632.
Gerritsz was apprenticed to W. J. Blaeu as an engraver before starting in business on his own account. He worked closely with Petrus Plancius and his merit may be judged by the fact that he was appointed Cartographer to the Dutch East India Company in preference to Blaeu and subsequently held the same position in a newly formed West India Company. With the new company he came into touch with Johannes de
Laet for whom he prepared a number of new maps of America in the latter's Nieuwe Wereldt published in 1625. His most important early work was a chart showing Henry Hudson's discoveries in his voyage of 1610-11: it is the first to give an outline of Hudson's Bay and indicates Hudson's belief that he had found a way to the North West Passage.
Engraver, cartographer, publisher and bookseller, b. Assum, apprenticed as engraver to Blaeu, Cartographer to Dutch E.
