Take the time to study the stars for a while; you'll find that they fall into patterns, designs imposed by your mind. Ancient skywatchers perceived stellar patterns and passed them on such patterns are called Constellations. Early named constellations marked a convenient group of stars, with ill-defined boundaries, that typically outlined a mythological or realistic figure.
