Nor do the Celtic peoples appear to be without a traditional remembrance of the mythical ancestor. The leading Celtic people of Gaul, in the time of Cæsar, were the _Ædin_, and Davies thought that their name was derived from _Aedd_ the Great, whom he finds referred to in the Welsh triads, and whom he identifies with _Aides_ or _Dis_. Cæsar, indeed, says that the god _Dis_ was the mythical ancestor of the Gauls. The position occupied by this deity in the traditions of the Celtic race is very remarkable, when we consider that a divine person bearing the same name was known, not only to the Greeks, but apparently also to the Babylonians. Sir Henry Rawlinson points out that _Dis_ should be one of the names of _Anu_, the first member of the leading Chaldean triad, and the deity who answered to _Hades_ or _Pluto_. _Warka_ or _Urka_, the great necropolis of Babylon, was especially dedicated to _Anu_, and Sir Henry Rawlinson remarks on this: “Can the coincidence then be merely accidental between _Dis_, the Lord of _Urka_, the City of the Dead, and _Dis_, the King of Orcus or Hades?” Most certainly not, as it is only one of many circumstances which prove the close connection of the Greeks and other Aryan peoples with the ancient Babylonians. The original character of _Dis_, “Lord of the Dead,” was probably the same as that of the Gallic _Dis_, _i.e._, the mythical ancestor of the race. A similar change of character has been undergone by the Hindu _Yama_. It is very probable that in the divine ancestor _Dis_, as in the mythical King _It_ of the Hindus, we have reference to the primeval _Ad_.[227] A common relationship as Adamites may be shown, as well by association with the Medes, through their title _Már_, as by preservation of a tradition of the common ancestor.
