In the second engagement the poet informs us that the Titans were quite discomfited and ruined: and according to the mythology of the Greeks, they were condemned to reside in Tartarus, at the extremity of the known world. A large body of Titanians, after their dispersion, settled in Mauritania: which is the region called Tartarus. The mythologists adjudged the Titans to the realms of night merely from not attending to the purport of the term ζοφος. This word described the West, and it signified also darkness. From this secondary acceptation the Titans of the West were consigned to the realms of night: being situated, with respect to Greece towards the regions of the setting sun. Bryant.

This, perhaps, suggested to Milton the arming the angels with mountains:
They pluck’d the seated hills with all their load;
Rocks, waters, woods; and by the shaggy tops
Uplifting, bore them in their hands.
