  • 10th-century Byzantine: /ma.ɣniˈsi.a/[1]

Forms

Μᾰγνησῐ́ᾱ (Magnēsíā) f (genitive Μᾰγνησῐ́ᾱς); first declension[1] Ionic Μαγνησίη.[2][3]

Etymology

It is formed from Ancient Greek Μάγνης (Mágnēs, “a Magnesian”) + -ία (-íā), “land of the Magnesians”.[1][2][4] The people's name Μάγνης (Mágnēs), plural Μάγνητες (Mágnētes), is of uncertain origin and perhaps Pre-Greek.[1][5] A Thessalian inscription of the 3rd century BC has the dative plural Μαγνείτεσσι (Magneítessi).[6]

Earliest recorded meaning

It is first found in Simonides and then in Herodotus, of a coastal region of Thessaly, and Herodotus also uses it of the city of the Magnesians in Asia Minor.[2][3]

Semantic evolution

The Thessalian Magnesia was the coastal land from the Peneius to the Gulf of Pagasae, filled by Mount Ossa and Mount Pelion; its harbourless east coast wrecked the fleet of Xerxes in 480 BC.[6] The Iliad already knows the Magnetes and their land, as the kingdom of Philoctetes.[6] Magnesia on the Maeander was said to have been founded from Thessalian Magnesia, and another city, Magnesia in Lydia, was distinguished from it.[6][7][8] The name of Magnesia in Asia Minor lives on in Turkish Manisa.[1]

From the region came the name of the magnet: Euripides and Plato call it the “Magnesian stone”, Μαγνῆτις (Magnêtis) λίθος, and the Hippocratic writers say Μαγνησίη (Magnēsíē) λίθος.[3][9] Theophrastus uses the same phrase for a silvery mineral, probably a kind of talc, and in the alchemists, from Zosimus on, lowercase μαγνησία names several ores and alloys.[3] Through Medieval Latin magnēsia this became English magnesia in the late 14th century, an ingredient of the philosopher's stone in alchemy.[5] Modern Greek μαγνησία (magnisía) is a learned word for compounds of magnesium, and Μαγνησία is still the name of the Thessalian regional unit.[10][11][12]
