Caelestis was the Carthaginian (North Africa) moon goddess who became the Romanized form of the Punic goddess Tanit. Elsewhere she was syncretized into the cult of Aphrodite–Venus.
The annual games were held in her honor. She was brought to Rome in an abstract block of stone (like that of Kybele from Pessinus). And became popular there diring the early part of the third century AD; in this guise she became known as the «mighty protectress of the Tarpeian hill.»
