But for our purpose the earth must be more than damaged, it must be
submerged. In fact, the disasters described are merely the prelude
to destruction. After that, the seas swell far beyond their wonted
bounds, sending out their waves far above the farthest high-water
mark of the most violent tempest. The winds will urge them on from
the rear, rolling up huge billows that will break far inland out of 3
sight of the highest shore. In course of time the shore will thus be
shifted forward, the deep will be established in a realm that is not
its own; the mischief will come nearer, and from its new base the tide
will issue still from the deepest recesses of the main. For just like
atmosphere and ether, this element, sea, has a large reserve, and in
its depth is far more copious than appears to the eye. This reserve,
moved by fate, not merely by tides--for tides are but the agency of
fate--raises and drives before it a gulf of vast extent. Then in 4
wondrous wise it rears its crest, and overtops all man’s refuges
of safety. Nor do the waters find this a hard task, since, if the
heights were calculated, it would be found that the sea mounts from an
elevation equal to that of earth. The surface of the sea is of uniform
level; for the earth itself as a whole is uniformly level. Hollows and
plains are everywhere below the general level.
But the whole globe is as a matter of fact formed into a regular
sphere, while in part of it is the sea, which unites to form the unity
of a single ball. But just as when one looks out across a plain, the 5
ground that sinks gradually deceives the eye, so we are not aware of
the sea’s curvatures, and all that is visible is a plain. But being on
a level with the earth, the sea does not require to raise itself to
any great height in order to overflow. In order to overtop what is on
a level with it, it need make only a slight rise. Besides, the flow
of it does not proceed from the shore where it is lower, but from mid
ocean where the heap in question stands. Therefore, as the tide at the
equinox soon after the conjunction of moon and sun rises to a height 6
greater than at any other time of year; in like manner this one that is
sent out to seize upon the earth must exceed in violence the highest
of ordinary tides, and bear a far greater volume of water; nor does
it begin to ebb until it has swollen above the peaks of the mountains
that are its objective. Some localities have at present a tide that
runs up inland for a hundred miles in ordinary course harmlessly. It
flows up to its normal limit and then ebbs again. But when the time of
deluge comes, the tide, freed from all restraint, will set no limit 7
to its advance. In what way? you say. Just in the same way as the great
conflagration is destined to take place. Both will take place when God
has seen fit to end the old order, and bring in a better. Fire and
water are lords of the earth. From these it took its rise, and in these
