diadem

diadem: [13] A diadem was originally something that was bound round someone’s head. The word comes, via Old French diademe and Latin diadēma, from Greek diádēma; this was a derivative of diadein, a compound verb formed from the prefix dia- ‘across’ and dein ‘bind’. In Greek it was often applied specifically to the regal headband worn by Alexander the Great and his successors.

late 13c., from Old French diademe and directly from Latin diadema "cloth band worn around the head as a sign of royalty," from Greek diadema, from diadein "to bind across," from dia- "across" (see dia-) + dein "to bind," related to desmos "band," from PIE *de- "to bind." Used of the headband worn by Persian kings and adopted by Alexander the Great and his successors.
