References to the diadem in the book of Revelation include 12:3, 13:1, and 19:2.
“The diadem is the sign of royal status. Rev 12:3: the dragon had “seven diadems” on his seven heads; 13:1: the beast had “ten diadems” on his ten horns; 19:12: the rider of the white horse had “many diadems” on his head.” (Exegetical dictionary of the New Testament (Vol. 1, p. 298).
This is one of the literally thousands of interesting artifacts in the British Museum, so many of which can be used in the context of biblical teaching/illustrations, etc.
