Euctemón
Sign in to saveEuctemon (, gen. Εὐκτήμονος; fl. 432 BC) was an Athenian astronomer. He was a contemporary and collaborator of Meton, who developed the 19-year Metonic cycle, which synchronises 235 lunar months with 19 solar years to form the basis of ancient Greek calendrical systems. Little is known of his work apart from his partnership with Meton and what is mentioned by Ptolemy. With Meton, he made a series of observations of the solstices (the time or date (twice each year) at which the sun reaches its maximum or minimum declination, marked by the longest and shortest days (about 21 June and 22 December

Euctemón fue un astrónomo ateniense. Fue contemporáneo de Metón y trabajó estrechamente con él. Poco se conoce de su trabajo aparte de su asociación con Metón y que es mencionado por Ptolomeo. Con Metón, hizo una serie de observaciones de los solsticios (los puntos en los que el sol está a mayor distancia del ecuador) para determinar la longitud del año tropical. Gémino de Rodas y Ptolomeo lo citan como una fuente sobre la salida y la posición de las estrellas.
