History
"Scorpion's claws" is zubānā in Arabic and zibanitu in Akkadian. In ancient Mesopotamia, a weighing scale was often the arm and the pans without a stand, and to use it was hung up by a string tied to the midpoint of the arm. A resulting fancied resemblance to a scorpion hung up by the end of its tail resulted in the Akkadian word zibanitu also being used to mean "weighing scale". The constellation was refigured by taking the other meaning of zibanitu.
