Pronunciation

  • 5th-century BC Attic: /di.á.dɛː.ma/[1]
  • 4th-century AD Koine: /ðiˈa.ði.ma/[1]
  • 10th-century Byzantine: /ðiˈa.ði.ma/[1]

Forms

δῐᾰ́δημᾰ (diádēma) n (genitive δῐᾰδήμᾰτος); third declension[1]

Etymology

It is from Ancient Greek διαδέω (diadéō, “to bind round”) with the result-noun suffix -μα (-ma),[1][2][3] the verb being made of διά (diá, “through, across”) and δέω (déō, “to bind”).[4][5]

Earliest recorded meaning

Xenophon's Cyropaedia first records it, of the band that Cyrus wore round his tiara.[2][6][7]

Semantic evolution

The band round the tiara was the mark of the Persian king, and Alexander adopted it, together with the Macedonian felt hat, and his successors wore it, so that the διάδημα became the sign of kingship generally.[2][6][3][8] The New Pauly notes that the term first covered any band worn round the head, as distinct from a wreath, and that diadems marked dignity, especially in cult.[9] The Septuagint uses it for a crown and for the royal headband of Esther, and in Revelation the dragon and the beast wear diadems.[10][8] A Pharaonic title was rendered “lord of the diadem”, and the phrase was later applied to Byzantine emperors.[6]

It was borrowed as Latin diadema, the source, partly through Old French, of English diadem (about 1300).[11][12] Medieval Greek kept it for a royal crown, and it remains the learned Modern Greek διάδημα (diádima).[13][14][4]
