The "bride's wreath" is a Christian substitute for the gilt coronet all Jewish brides wore. The crowning of the bride is still observed by the Russians, and the Calvinists of Holland and Switzerland. The wearing of orange blossoms is said to have started with the Saracens, who regarded them as emblems of fecundity. It was introduced into Europe by the Crusaders. The "bride's veil" is the modern form of the "flammeum" or large yellow veil that completely enveloped the Greek and Roman brides during the ceremony. Such a covering is still in use among the Jews and the Persians.
