«Of the stars in the body of Scorpio, the bright stars on the forehead act in the same way as does Mars and in some degree as does Saturn; the three in the body, the middle one of which is tawny and rather bright and is called Antares, the same as Mars and, in some degree, Jupiter; those in the joints, the same as Saturn and, in some degree, Venus; those in the sting, the same as Mercury and Mars; and the so-called cloud-like cluster, the same as Mars and the moon» (Tetr. I,9).
