The Algolrithm.

“Historically, the star has received a strong association with bloody violence across a wide variety of cultures. In the Tetrabiblos, the 2nd-century astrological text of the Alexandrian astronomer Ptolemy, Algol is referred to as "the Gorgon of Perseus" and associated with death by decapitation: a theme which mirrors the myth of the hero Perseus's victory over the snake-haired Gorgon Medusa.[50] In the astrology of fixed stars, Algol is considered one of the unluckiest stars in the sky,[43] and was listed as one of the 15 Behenian stars.[51]” wikipedia, Algol.
