Perseus is a constellation
named after the Greek Hero Perseus (who stars in the newest Titans movie series).
If we continue the slightly curved line on which we found all the principal stars of Andromeda
, some 12 east beyond Almach, we reach Mirfak, the brightest star in Perseus.
Perseus is east of Andromeda and directly north of the Pleiades
. It contains many fine stars, one other, Algol, being 2m. Algol is one of the most wonderful stars in the sky. For about two and one-half days it is a 2m star when its light slowly fades for three and a half hours until it is a 4m star, but after three and a half hours more it regains its original brightness. This was noticed by the ancient Arabs, as the name they gave it shows. Algol means demon. For many ages the cause of the variation was unknown. But it is now known that Algol has a dark companion around which it revolves, and which hides part of its light at each revolution. Algol may easily be located. A line drawn to it from Mirfak and another from Almack, forms a right triangle at Algol, which opens directly toward Cassiopeia
Algol has a small star very near it and nearly south of it, by which it may also be known. The other conspicuous stars of Perseus are scattered on each side of Mirfak, forming an irregular line toward Cassiopeia.
The Myth discussed here is also depicted in the movie series the Titans. The mythological stories of the four above-named constellations are inseparable. Cepheus
was King of Ethiopia ; Cassiopeia was his wife and Queen, and Andromeda was their daugter. Cassiopeia was a queen of matchless beauty, and she boasted that she was more beautiful than Juno and the sea nymphs, or Nerides. Juno and the nymphs were highly insulted and they
complained to Neptune, and he sent a frightful monster to ravage the coast of Ethiopia. Cepheus and his Queen consulted the oracles and were informed that nothing short of the sacrifice of their daughter Andromeda to the jaws of the seamonster would appease the wrath that had been awakened. Andromeda was therefore chained to a rock to await her doom when Perseus with his feet- wings came flying through the air.
Perseus, the son of Jupiter
and Danae, was cast as soon as born into the sea with his mother. They were rescued by a fisherman and carried to the king of one of the islands of the Cyclades where Perseus grew to manhood. At a feast of the King Perseus engaged to bring him the head of Medusa, one of the three Gorgons, which had power to turn to stone anything they looked upon. Mercury
lent him wings for his feet, and a dagger. He found the gorgons sleeping, cut off the head of Medusa, and fled with it bleeding through the air. When he came upon the princess Andromeda, chained to a rock, he fell in love with her and proposed to her father that he would save her from the monster, if she might marry him. Cepheus promised and Perseus turned the eye of the reeking head upon the monster and changed it to stone. The nuptials were soon celebrated and the royal family lived happily. All of the four were translated to the sky after death. Perseus in the constellation still holds the head of Medusa, and the eye with which he destroyed the sea-monster is the blinking star, Algol.
