Pronunciation

  • 5th-century BC Attic: /mé.dɔː/[1]
  • 4th-century AD Koine: /ˈme.ðo/[1]
  • 10th-century Byzantine: /ˈme.ðo/[1]

Forms

μέδω (médō) [1] Only the present is attested; the middle μέδομαι (médomai) also has the future μεδήσομαι (Iliad 9.650).[2][3] A by-form μεδέων (medéōn), feminine μεδέουσα, is found in the Iliad, the Homeric Hymns and Hesiod.[2][4]

Etymology

It is inherited from Proto-Indo-European *med- (“to measure, take care”), a root that LIV glosses as “measure, ensure compliance, take care”,[5] and Greek continues its acrodynamic root present in μέδω and the middle μέδομαι (médomai).[5][2] Wiktionary reconstructs the present as *méd-e-ti.[1]

In the sense “think of, be prepared for”, the middle corresponds exactly to Latin meditor (“to reflect, meditate”), beside which Latin has medeor (“to heal”) and modus (“measure”).[2] Other cognates are Old Irish midithir (“judges”), Gothic 𐌼𐌹𐍄𐌰𐌽 (mitan, “to measure”), Old English metan (“to measure”) and German messen (“to measure”).[2][5][4] Chantraine, following Benveniste, defines the root as “to take with authority the appropriate measures”.[4] A thought that rules and orders gave the sense “rule” in Greek and legal terms in Italic, such as Oscan meddiss (“one who pronounces the law”),[4] the healer's measures gave the Latin verb for healing and Avestan vīmad- (“physician”),[4] and Germanic specialised the root as “measure”.[4]

μήδομαι (mḗdomai, “to devise”) has been explained as a lengthened grade of the same root, but Beekes allows that it may come from a different root, Proto-Indo-European *meh₁(d)-.[2]

Earliest recorded meaning

Homer uses only the participle μέδων (médōn), as a noun, “lord, ruler”, mostly in the plural in the formula ἡγήτορες ἠδὲ μέδοντες, “leaders and rulers”, and once in the singular for the lord of the sea in the Odyssey.[3][4] The middle μέδομαι, “to provide for, be mindful of”, with the genitive, is Homeric too: πολέμοιο μεδέσθω, “let him think of war” (Iliad 2.384).[3][2]

Semantic evolution

Hesiod gives the feminine participle as the name of the Gorgon Μέδουσα (Médousa), “she who rules”, and the by-form μεδέων (medéōn) appears in the Iliad and the Hymn to Hermes.[3][2][4] The root is common in names: Μέδων, Λαομέδων (Laomédōn), and the Boeotian town Μεδεών, perhaps “seat of government”.[2][4]

The finite verb appears only in 5th-century poetry, with a genitive of the place or thing ruled.[3][6] In Sophocles a god rules over a place: Poseidon over a headland of the Aegean, a line Aristophanes quotes in the Frogs, and Dionysus over Eleusis in the Antigone.[3][6] Empedocles says that each of the elements has charge of its own prerogative.[3][6] Only the present is found.[2][4] The middle μέδομαι later takes an infinitive in the Orphic Argonautica, “to plan to sail”.[3]

Timeline

  • Homer – The Iliad and the Odyssey use the participle μέδων (médōn) for “ruler” and the middle μέδομαι (médomai) for “to be mindful of”.[3][4]
  • Before the 6th century BC – Hesiod names the Gorgon Medusa with the feminine participle.[3][2][7]
  • 5th century BC – Empedocles and Sophocles use the finite verb, of an element and of gods ruling over places.[3][6][7]
  • 5th–4th century BC – Aristophanes quotes Sophocles' line on Poseidon in the Frogs.[3][6][7]
