In this original Aryan notion, however, as represented by the figure, we have more than this, the origin of the names _Jupiter_ and _Deus_ comes out. For it is easy to trace the connection between _Dyaus_ (the luminiferous air) and the Greek word _Zeus_ from whence _Dios_, [Greek: _theos_], _Deus_, and the French word _Dieu_, and then by adding _pater_ or father we get _Deuspater_, _Zeuspater_, Jupiter. These etymologies are not however matters beyond dispute, and there are at least two other modes of deriving the same words. Thus we are told the earliest name for the Deity was Jehovah, the word _Jehov_ meaning father of life; and that the Greeks translated this into _Dis_ or _Zeus_, a word having, according to this theory, the same sense, being derived from [Greek: zao] to live. Of course there can be no question of the later word _Deus_ being the direct translation of _Dios_. A third theory is that there exists in one of the dialects which formed the basis of the old languages of Asia, a word _Yahouh_, a participle of the verb _nih_, to exist, to be; which therefore signifies the self-existent, the principle of life, the origin of all motion, and this is supposed to be the allusion of Diodorus, who explaining the theology of the Greeks, says that the Egyptians according to Manetho, priest of Memphis, in giving names to the five elements have called the spirit or ether Youpiter in the _proper sense_ of the word, for the spirit is the source of life, the author of the vital principle in animals, and is hence regarded as the father or generator of all beings. The people of the Homeric ages thought the lightning-bearing Jupiter was the commencement, origin, end, and middle of all things, a single and universal power, governing the heavens, the earth, fire, water, day and night, and all things. Porphyry says that when the philosophers discoursed on the nature and parts of the Deity, they could not imagine any single figure that should represent all his attributes, though they presented him under the appearance of a man, who was _seated_ to represent his immovable essence; uncovered in his upper part, because the upper parts of the universe or region of the stars manifest most of his nature; but clothed below the loins, because he is more hidden in terrestrial things; and holding a sceptre in his left hand, because his heart is the ruler of all things. There are, besides, the etymologies which assert that Jupiter is derived from _juvare_ to help, meaning the assisting father; or again that he is _Dies pater_--the god of the day--in which case no doubt the sun would be alluded to.
