Western Africa and Spain. Murray tells us ("Mythology," p. 58) that
Pluto's share of the kingdom was supposed to lie "in the remote west."
The under-world of the dead was simply the world below the western
horizon; "the home of the dead has to do with that far west region where
the sun dies at night." ("Anthropology," p. 350.) "On the coast of
Brittany, where Cape Raz stands out westward into the ocean, there is
'the Bay of Souls,' the launching-place where the departed spirits sail
off across the sea." (Ibid.) In like manner, Odysseus found the land of
the dead in the ocean beyond the Pillars of Hercules. There, indeed, was
the land of the mighty dead, the grave of the drowned Atlanteans.

"However this be," continues F. Pezron, "the empire of the Titans,
according to the ancients, was very extensive; they possessed Phrygia,
Thrace, a part of Greece, the island of Crete, and several other
provinces to the inmost recesses of Spain. To these Sanchoniathon seems
to join Syria; and Diodorus adds a part of Africa, and the kingdoms of
Mauritania." The kingdoms of Mauritania embraced all that north-western
region of Africa nearest to Atlantis in which are the Atlas Mountains,
and in which, in the days of Herodotus, dwelt the Atlantes.

Neptune, or Poseidon, says, in answer to a message from Jupiter,

No vassal god, nor of his train am I.
Three brothers, deities, from Saturn came,
And ancient Rhea, earth's immortal dame;
Assigned by lot our triple rule we know;
Infernal Pluto sways the shades below:
O'er the wide clouds, and o'er the starry plain
Ethereal Jove extends his high domain;
My court beneath the hoary waves I keep,
