Coma Berenices
In the work by anonymous author from the year 379 Coma Berenices is shown as " Leo's braids". Bayer (1603) represents it as a sheaf of corn under the tail of the Greater Bear-Ursa Major (Alkaid, Mizar e Alioth), between Arcturus and the Lion's tail (Denebola). Mel 111, an open cluster of about 80 stars that appears as a small, milk-like mass, lies in the central zone of Coma. The small stars of Coma justify the fact that this asterism belongs to the catalogue of "passional" stars, stars of passion (the brightest one is gamma, magnitude 4.36, all the other have the fifth magnitude); this star-cluster renders this zone "harmful to the sight".
