They are especially noteworthy as illustrating the ancient legend of Perseus and Andromeda, one of the best known of all the classic myths and one that has survived all ages. It shows clearly that there was an effort made on the part of the inventor of these constellations to depict here on the imperishable scroll of heaven a drama that should survive all time.

This seems fairly good proof that some of the constellations, at least, were carefully thought out by one man, that design and not chance was responsible for their creation, and that the legends they represented antedated the invention of the several star groups.
