Perseus had turned the monster into stone by holding the blood-freezing head of Medusa before his eyes; and it was fear lest Andromeda herself might see the Gorgon's head, and suffer the fate of all who looked upon it, that had led him to forbid her watching him when he attacked her enemy. Afterward he married her, and Cassiopeia, Andromeda's mother, and Cepheus, her father, gave their daughter's rescuer a royal welcome, and all the Ethiops rose up and blessed him for ridding the land of the monster. And now, if we choose, we can, any fair night, see the principal characters of this old romance shining in starry garb in the sky. Aratus saw them there in his day, more than two hundred years before Christ, and has left this description in his "Skies," as translated by Poste: "Nor shall blank silence whelm the harassed house Of Cepheus; the high heavens know their name, For Zeus is in their line at few removes. Cepheus himself by She-bear Cynosure, Iasid king stands with uplifted arms. From his belt thou castest not a glance To see the first spire of the mighty Dragon. "Eastward from him, heaven-troubled queen, with scanty stars But lustrous in the full-mooned night, sits Cassiopeia. Not numerous nor double-rowed The gems that deck her form, But like a key which through an inward-fastened Folding-door men thrust to knock aside the bolts, They shine in single zigzag row. She, too, o'er narrow shoulders stretching Uplifted hands, seems wailing for her child. "For there, a woful statue-form, is seen Andromeda, parted from her mother's side. Long I trow Thou wilt not seek her in the nightly sky, So bright her head, so bright Her shoulders, feet, and girdle. Yet even there she has her arms extended, And shackled even in heaven; uplifted, Outspread eternally are those fair hands. "Her feet point to her bridegroom Perseus, on whose shoulder they rest. He in the north-wind stands gigantic, His right hand stretched toward the throne Where sits the mother of his bride. As one bent on some high deed, Dust-stained he strides over the floor of heaven." The makers of old star-maps seem to have vied in the effort to represent with effect the figures of Andromeda, Perseus, and Cassiopeia among the stars, and it must be admitted that some of them succeeded in giving no small degree of life and spirit to their sketches. The starry riches of these constellations are well matched with their high mythological repute. Lying in and near the Milky-Way, they are particularly interesting to the observer with an opera-glass. Besides, they include several of the most celebrated wonders of the firmament.
