Saturn

• n. [空]土星；農耕の神（ローマ神話の人物）

古英語のSaeternから、ラテン語のSaturnus（農耕の神）に由来し、おそらくsaturus（種をまく人）、serere（種をまく）の過去分詞からきている。

Saturn

Old English S?tern, a Roman god, also "most remote planet" (then known), from Latin Saturnus, originally a name of an Italic god of agriculture, possibly from Etruscan. Derivation from Latin serere (past participle satus) "to sow" is said to be folk-etymology.

An ancient Italic deity, popularly believed to have appeared in Italy in the reign of Janus, and to have instructed the people in agriculture, gardening, etc., thus elevating them from barbarism to social order and civilization. His reign was sung by the poets as "the golden age." [Century Dictionary]

Identified with Greek Kronos, father of Zeus. Also the alchemical name for lead (late 14c.). In Akkadian, the planet was kaiamanu, literally "constant, enduring," hence Hebrew kiyyun, Arabic and Persian kaiwan "Saturn." Related: Saturnian.
