It's also said that the custom of covering the bride with a veil that stayed over her face until the end of the ceremony was to keep the groom from seeing what he was getting and running off, but that's actually probably not true. (More likely, it was to keep "evil spirits" from seeing her and doing, well, evil things to her, or some such.)
An awful lot of wedding traditions and rituals are ancient and shrouded in mystery as to their origins, but they're just superstitions.
