Pronunciation

  • Classical: [saːˈtʊr.nʊs][1]
  • Ecclesiastical: [saˈtur.nus][1]

Forms

Sāturnus m (genitive Sāturnī); second declension[1] Old spellings are Saeturnus, on an inscription, and Sateurnus, reported by Festus.[2][3]

Etymology

The origin is uncertain.[2][1] Wiktionary takes it to be probably borrowed from Etruscan 𐌔𐌀𐌕𐌓𐌄 (satre),[1] and the OLD calls the god perhaps of Etruscan origin.[2] Others derive the name from serō1 (“to sow”), through its participle satus1;[4][3][5] Wiktionary and Etymonline treat that derivation as a folk etymology.[1][6] Ancient grammarians already connected the god with sowing: Varro derived the name from the sowing of crops,[3] and Isidore adds that he might be named from being sated with years.[7]

Earliest recorded meaning

The name is first found in Livius Andronicus (280/260–before 200 BC), who addresses a god as Saturni filie “son of Saturn”.[2][5]

Semantic evolution

Saturn was an old Italic god, commonly identified with the Greek Kronos; legend made him an ancient king of Latium.[2][3] He was worshipped as a god of sowing, with Ops as his wife.[4] The name was used for the planet (stella or sidus Saturni, or Saturnus alone), and dies Saturni was the seventh day of the planetary week, especially the Jewish sabbath.[2] Curtius applies it to Moloch, worshipped at Tyre.[2]

In medieval alchemy Saturnus was the name of lead.[8][5] Dies Saturni continued as the name of Saturday,[8] and Old English took the name of the god and planet as Sætern.[6]
