Name origin

Ultimately from the Arabic word al-mi)zar, "the girdle" or "loin cloth", used in the Arabic Almagest in describing this star. The correct transliteration of the word in the Medieval Latin Almagest was mizar, which was occasionally misspelled as mirac, mirat, etc. These corruptions, taken as proper names for β And, were correctly attributed to al-mi)zar by Renaissance scholars. Subsequently one of the misspellings, "Mirach", gained more popularity over the correct "Mizar", to beome the preferred modern name.
