Name origin

The specific origin of this name is unclear. It may represent a transfer from β Peg, where alferaz and other variants were applied in medieval times as abbreviations for β Peg's Arabic name mankib al-faras, "the Horse's Shoulder". Or, it may be from an abbreviation of the name alpheraz id est equus, "alpheraz, that is, the Horse", which was applied directly to α And also in medieval times. In any case, Medieval Latin authors confused these two names, their spellings, and their identifications, and the modern application of "Alpheratz" to α And comes down to us from late medieval times.
