History of the Christmas wreath

The word 'wreath' comes from the Old English word 'writhen' which means to writhe or twist. Before the wreath became associated with Christmas, it was a prominent emblem of victory and power in ancient Greece and Rome. Rich Roman women also wore them as headdresses at special occasions like weddings and to show they were posh. They were also given to the winners of events in the original Olympic Games in Greece.
