Reply #1: Nah. But it's easy to see how the superstition developed.

BREAKING A MIRROR

This will bring you 7 years of bad luck or might cause the death of someone in the family. If a mirror is broken, remove it from the house and, if possible, bury it in the ground (to counteract the evil consequences).

Origin: Before the invention of mirrors, man gazed at his reflection, his "other self," in pools, ponds, and lakes. If the image was distorted, it was a mark of impending disaster. The "unbreakable" metal mirrors of the early Egyptians and Greeks were valued items because of their magical properties. After glass mirrors were introduced, it was the Romans who tagged the broken mirror a sign of bad luck. The length of the prescribed misfortune, 7 years, came from the Roman belief that man's body was physically rejuvenated every 7 years, and he became, in effect, a new man.
