Kallistos, although I don't agree with you on the topic, it is not the issue I want to raise at present.

I'll just remark that you may want to change the wording of your article for the sake of accuracy, for where you write crown you naturally mean diadem.

A diadem, a simple white band worn around the head and knotted at the back, was the symbol of royalty in ancient times.

A crown or wreath (corona) was
a. a Roman military decoration, of which Caesar had several (the first was the corona civica awarded to him at Mitylene for saving the life of a comrade in battle);
b. a wreath of flowers used commonly at parties and festivals

Nevertheless, the medieval and modern royal crowns do probably have their origin in the Roman military crowns

I am trying to write something for the Codex but can make no promises; it's been really busy at work and I am usually too tired to be creative.

I enjoyed reading both online articles :-)
