Wedding Veils are actually used to ward off evil spirits. Ancient Greek and Roman tradition states that wearing a wedding veil helps to ward off evil spirits intent on cursing the bride... The veil was supposed to hide the bride's face from demons and witches— with a veil over her head they couldn't see her, and so couldn't curse her. Gives a whole other meaning to wearing a veil... We still think they are simply beautiful.
