It is a modern popular misconception that the ancients named the constellations after certain animals or mythical beings because they thought they could see the shapes of animals or people in the star designs.
They also believed that the far-flung regions of the Celestial Sphere had specific properties, especially along the longitudinal lines (north and south), so that stars in Constellations above and below each other tended to have similar 'natures' and were thus somewhat related to each other. The ancients believed that each constellation had different 'regions', each of which had a special 'flavor' or 'nature' which might be different from other parts of the same constellation - and startlingly different from other regions of the Celestial Sphere. To understand this Astrological Nature, it is important to understand how the ancient astrologers viewed the heavens. The STAR OF ANTINOUS rules all homosexuals, and its position in a Natal Chart says much about the Astrological Nature of a gay person.
