diadem

Etymology

It is inherited from Middle English diademe,^[2][3][4] borrowed from Old French diademe,^[5][6][4][7] and directly borrowed from Latin diadēma (“cloth band worn round the head as a sign of royalty”),^[4][8][6] from Ancient Greek διάδημα (diádēma, “band, fillet, especially the royal headband of the Persian kings”),^[5][6][9] from διαδέω (diadéō, “to bind across, bind round”),^[5][6][9] formed from διά (diá, “across, through”) and δέω (déō, “to bind”),^[5][6] from Proto-Indo-European *dē- (“to bind”).^[6][8] The verb for binding is related to δεσμός (desmós, “band”).^[8][6][9] The Anglo-Norman form is recorded from about 1270, for a crown and for a representation of the crown of thorns.^[10]

Earliest recorded meaning

The aureole or crown of a martyr or confessor: about 1290, in the South English Legendary.^[5] Etymonline and Barnhart date the word to about 1300,^[6][8] and Merriam-Webster Unabridged to the 13th century.^[3]

Semantic evolution

The Greek word was applied to the headband worn by Persian kings and adopted by Alexander the Great and his successors.^[5][6][11] English borrowed the word in a wider sense, as a crown of any kind, and then as a figure for royal authority,^[5][2] and the original headband is recorded in English only from 1579, in North's translation of Plutarch.^[5] Chaucer used diademe five times and Gower three times.^[12] A wreath of leaves or flowers was called a diadem from 1530.^[5][13] From the 16th century the word could mean anything that lends glory or dignity, like John Neal's "it was a diadem there", said of the name Yankee.^[5][13] From 1782, in Cowper, it was anything that crowns the top of something,^[5] as in Byron's Mont Blanc "With a diadem of snow".^[13] Johnson (1755) separates the band of Eastern monarchs from the crown,^[14] and the Shorter Oxford notes that the noun is now chiefly poetic and rhetorical.^[13] In surgery the Latin form diadema was used from 1811 for a head bandage.^[5] The name was also given to the diadem monkey and the diadem spider.^[13]
