Greek astronomer from 310-230 BC. From the island of Samos. Known as the creator of the heliocentric system of the universe. In Greece, the Pythagoreans had a system in which all celestial bodies, including the Sun and the Earth, revolved around a central fire, and Herakleides of Pontos (c. 388-c. 315 BC) is said to have considered the rotation of the Earth on its axis, but Aristarchus was the first to consider the rotation of the Earth on its axis and its revolution around the Sun.

前310ころ‐前230ころ ギリシアの天文学者。サモスSamos島の人。太陽中心的な宇宙体系(地動説)の創案者として知られている。ギリシアにおける地動説としては,ピタゴラス派に〈中心火〉なるものの周囲を,太陽,地球を含むすべての天体が回転するという体系はあるし,ポントスPontosのヘラクレイデスHērakleidēs(前388ころ‐前315ころ)は地球の自転を考えたといわれるが,地球の自転と太陽を回る公転とを考案したのはアリスタルコスが最初といってよい。 出典 株式会社平凡社世界大百科事典 第2版について 情報 |
