Diadem

[Gr. diadem a, from diadeō, to bind round - dia, and deō, to bind.] A head-band or fillet worn by kings as a badge of royalty; the mark or badge of royalty worn on the head; a crown; a tiara. "Mont Blanc,... monarch of mountains, With a diadem of snow." - Byron. -Empire; supreme power; royalty; sovereignty. "Faction that once made diadems her prey." - Roscommon. (Her.) Although the crown and the diadem (see fig. 733) have been from ancient times confounded, yet the latter was a very different thing from what a crown now is, or was. The D. was a fillet of silk or linen; and no other crown was used, excepting in some Asiatic kingdoms, before the Christian æra. Diocletian a umed the D. in 303. After this time it was adorned with a single or double row of pearls and precious stones. It was finally superseded by the crown. crowned. Diademed, ( di'a - demd ,) a. Adorned with a diadem; Diadex'is, n. [Gr. diadexomai , to transfer.] ( Med . ) A transformation of a disease into another, differing from the former both in its nature and seat.
