It is demonstrated that the longitudes of the planetary exaltations mentioned in numerous Greco-Roman and Late Antique astrological sources derive from Babylonian Normal-Star longitudes. This is achieved through a comparison between both sets of longitudes. Supporting evidence is found in the Late Babylonian astral compendium BM 36609+. The Babylonian longitudes were transferred to exaltations without significant changes, but their association with stars was discarded. The sun’s exaltation constitutes an exception, since it does not correspond to a Normal Star, but appears to have been defined in relation to the longitude of the Pleiades, which became the moon’s exaltation.
