The constellation COMA BERENICES represents the beautiful hair of
Queen Berenice of Egypt. She was so concerned for the safety of
her husband Ptolemy III when he went off to war, that she vowed to
cut off her glorious long hair as a sacrifice to Venus, should he
be spared. When he eventually returned safely home, she kept her
promise, and Zeus placed her beautiful hair in the heavens to
shine among the stars.
Another account suggests that this
constellation represents Thisbe's veil (see Legend of Leo).
