Pronunciation

  • IPA (5th-century BC Attic): /ai̯.ɡís/[1]
  • IPA (4th-century AD Koine): /ɛˈʝis/[1]
  • IPA (10th-century Byzantine): /eˈʝis/[1]

Forms

αἰγῐ́ς (aigís) f (genitive αἰγῐ́δος); third declension[1]

Etymology

It is usually taken as derived from αἴξ (aíx, “goat”), “goatskin”, formed like νεβρίς (nebrís, “fawnskin”) from νεβρός (nebrós, “fawn”).[2][3][1] Herodotus already took the aegis of Athena for a goatskin, a view that many modern scholars defend.[2][4]

Other explanations exist: a derivation from an unattested verb *αἴγω “to move, shake”, matching Sanskrit एजति (éjati, “moves, trembles”) (Kretschmer, Thumb), with αἴγλη “gleam”; or a link with αἴγειρος (aígeiros, “black poplar”), which would make it a wooden shield.[2][4][1] The sense “storm wind” was probably influenced by ἐπαιγίζω (epaigízō, “to rush upon”), used of winds.[2] Cunliffe thought the original idea was a storm cloud.[2][5][1]

Earliest recorded meaning

In the Iliad it is the terrifying shield of Zeus, which he shakes to rout armies.[4][5] Athena and Apollo also wield it, Athena casts it over Achilles' shoulders, and Apollo covers Hector's body with it.[5][3][4]

Semantic evolution

The CGL describes the Homeric aegis as apparently a metal shield covered with goatskin, fringed with golden tassels and bearing the Gorgon's head, Panic, Strife, Might and Rout.[6] Hesiod describes Athena shaking it so that the earth groans.[4] Later poets made it Athena's attribute and pictured it as a garment: in Pindar and Euripides it is fringed with snakes, in Aeschylus it is worn, and Euripides makes it of the Gorgon's skin.[6][3] Herodotus explains the aegis of Athena's statues from a goatskin dress.[4][3]

As an ordinary word it meant a goatskin, as in Euripides' Cyclops.[3][4] Aeschylus and Pherecrates use it for a storm wind, terrible as the shaken aegis.[3][6] Technical uses were the hard heartwood of the pine (Theophrastus) and a speck in the eye (Hippocrates).[3][1] Polybius uses it as a symbol of divine power.[6] English aegis, from Latin, means “protection” from 1793.[7]
