, or Meton, a celebrated mathematician of Athens, who flourished 432 B. C. was the son of Pausanias. He observed, in the first year of the 87th olympiad, the solstice at Athens, and published his cycle of 19 years, by which he endeavoured to adjust the course of the sun and moon, and to make the solar and lunar years begin at the same point of time. This is called the Metonic period, or cycle. It is also called the golden number, from its great use in the calendar. Meton was living about the year 412 B. C. for when the Athenian fleet was sent to Sicily, he escaped from being embarked on that disastrous expedition by counterfeiting an appearance of idiotism. 2
