 Mythology of Coma Berenices

Coma Berenices represents the hair of Queen Berenice of Egypt. According to legend, she cut off her locks to thank the gods for the safe return of her husband, King Ptolemy, from battle. It was formed in the 16th century by Gersrdus Mercator, the Dutch cartographer, from a group of faint stars that the Greeks regarded as the tail of Leo. The galaxies in its southern region belong to the Virgo Cluster.
