Diadem

di'a-dem, originally a head band, ribbon, or fillet passing around the head to hold back the hair. The ancients wore diadems of silk, linen, or wool, encircling the forehead and temples, the ends being tied behind, so as to fall on the neck. We may imagine that the diadem was at first a plain band of cloth or leather; but, worn by royalty and rank, it was early adorned with embroideries, gold work, pearls, and precious stones. In later days the diadem has developed into the ducal coronet and crown made of costly metals and adorned with princely magnificence. See Blanc
