- Name appears in Bayer's (1603) Uranometria for Upsilon Per (later designated 51 And), which he states is of Arab origin, however the name appears to be Latin not Arabic. From the description it appears that the name appears to be connected with the adamntine harpe sword Perseus used to decapitate Medusa.
