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 (constellation)|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]].<ref>Robbins, Frank E.
