‖ saros|ˈsɛərɒs|
[Gr. σάρος or σαρός (Berossos), a. Assyro-Babylonian šār(u.]
1. Antiq. The Babylonian name for the number 3600, and hence for a period of 3600 years.
The notion expressed in quot. 1662, that the saros consisted of 3600 days, is due to the desire to rationalize the incredible statements of Berossos with regard to the lengths of the reigns of the antediluvian kings of Babylon. Other expedients for the same purpose were adopted by early writers on chronology.

2. Astr. Adopted by modern astronomers as the name of the cycle of 18 years and 102/3 days, in which solar and lunar eclipses repeat themselves.
This use is founded on the statement of Suidas (app. due to some mistake) that the length of the saros was 18½ years.
