Pausanias has a number of passages which bear upon this subject, and seem to prove conclusively that the Greeks recognised the doctrine of a trinity in unity and worshipped the same. In his second book he says: "Beyond the tomb of Pelasgus is a small structure of brass, which supports the images of Diana, of Jupiter, and of Minerva, a work of some antiquity: Lyceas has in some verses recorded the fact that this is the representation of Jupiter Machinator." Again, in Book I., when describing the Areopagite district of Athens, he says:--"Here are the images of Pluto, of Mercury, and of Tellus, to whom all such persons, whether citizens or strangers, as have vindicated their innocence in the Court Areopagus, are required sacrifice." "In a temple of Ceres, at the entrance of Athens, there are images of the goddess herself, of her daughter, and of Bacchus, with a torch in his hand." That the grouping of the three deities was not accidental is evident from the frequency with which they are so mentioned, and other passages show that they were the three deities who were worshipped in the Eleusinian mysteries. Thus in Book VIII., Ch. 25:--"The river Lado then continues its course to the temple of the Eleusinian Ceres, which is situated in territories of the Thelpusians: the three statues in it are each seven feet high, and all of marble: they represent Ceres, Proserpine, and Bacchus." In another passage (Book II., Ch. 2) he says:--"By a temple dedicated to all the gods, there were placed three statues of Jupiter in the open air, of which one had no title, a second was styled the _Terrestrial_, and the third was styled the highest." The learned say, of course, it is clear that the missing title should have been the _God of the Sea_, as the others were the _God of Heaven_, and the _God of the Earth_. Another passage in Pausanias confirms this:--"In a temple of Minerva was placed a wooden image of Jupiter with three eyes; two of them were placed in the natural position, and the other was placed on the forehead.... One may naturally suppose that Jupiter is represented with three eyes as the God of the Heaven, as the God of the Earth, and as the God of the Sea."
