The chief seat of his worship is Huruk or Erech--the modern Warka--which becomes the favorite Chaldaean burying city, as being under his protection.

There are some grounds for thinking that one of his names was _Dis._ If this was indeed so, it would seem to follow, almost beyond a doubt, that _Dis,_ the lord of Orcus in Roman mythology, must have been a reminiscence brought from the East--a lingering recollection of _Dis_ or Ana, patron god of Erech (_Opex_ of the LXX), the great city of the dead, the necropolis of Lower Babylonia.

Further, curiously enough, we have, in connection with this god, an illustration of the classical confusion between Pluto and Plutus; for Ana is "the layer-up of treasures"-- the "lord of the earth" and of the "mountains," whence the precious metals are derived.
The worship of Ana by the kings of the Chaldaean series is certain.

Not only did Shanias-vul, the son of Ismi-dagon, raise a temple to the honor of Ana and his son Vul at Kileh-Shergat (or Asshur) about B.C.

1830-- whence that city appears in later times to have borne the name of Telane, or "the mound of Ana"-- but Urukh himself mentions him as a god in an inscription quoted above; and there is reason to believe that from at least as early a date he was recognized as the presiding deity at Erech or Warka.
