Formation

First attested

Borrowed from
Ancient Greek διάδημα
Ultimate origin
Ancient Greek (διαδέω)

Pronunciation

  • Classical: [di.aˈdeː.ma][1]
  • Ecclesiastical: [di.aˈdɛː.ma][1]

Forms

diadēma n or f (genitive diadēmatis or diadēmatos or diadēmae); variously declined, third declension, first declension[1] A first-declension diadēma, -ae (feminine) is found in Pomponius, Apuleius and later writers.[2][3]

Etymology

It is borrowed from Ancient Greek διάδημα (diádēma, “headband”),[2][4][1] from διαδέω (diadéō, “to bind round”) with the result-noun suffix -μα (-ma).[1]

Earliest recorded meaning

Lewis & Short's earliest dated examples are in Cicero's Philippics;[5] the comic writer Pomponius has the feminine form.[2]

Semantic evolution

It is an ornamental headband, usually white and tied at the back, worn as the emblem of a king, and so a diadem or crown.[2] By metonymy it is royal power itself, “the crown”: Horace has virtue bestowing kingdom and diadem on one man, and Livy speaks of wearing a crown bloodied by a brother's murder.[2] Pomponius uses it figuratively of supremacy in charm.[2] The Vulgate has it in the Apocalypse.[5] Church Latin glosses it diadem or crown.[6]

Timeline

  • 81–43 BC – Cicero uses it in the Philippics.[5][4]
  • 65–8 BC – Horace of the crown as royal power.[2][4]
  • 390–406 AD – the Vulgate of the crowns in the Apocalypse.[5][4]
  • c. 1300 – English diadem is borrowed through French.[7]
