1and ſport with our Fancies) hath, I ſay, hath permitted that the

motions for every other reſpect, except to reſolve the ebbing and
flowing of the Sea, aſſigned long ſince to the earth, ſhould be found
now at laſt to anſwer exactly to the cauſe thereof; and, as it

were, with mutual a emulation, the ſaid ebbing and flowing
to appear in confirmation of the Terreſtrial motion: the judices
whereof have hitherto been taken from the cœleſtial Phænomena,
in regard that of thoſe things that happen on Earth, not any one
was of force to prove one opinion more than another, as we
ready have at large proved, by ſhewing that all the terrene
rences upon which the ſtability of the Earth and mobility of the
Sun and Firmament is commonly inferred, are to ſeem to us
formed in the ſame manner, though we ſuppoſed the mobility of
the Earth, and the immobility of them.
The Element of
ter onely, as being moſt vaſt, and which is not annexed and
catenated to the Terreſtrial Globe as all its other ſolid parts are;
yea, rather which by reaſon of its fluidity remaineth apart ſui
juris, and free, is to be ranked amongſt thoſe ſublunary things,
from which we may collect ſome hinte and intimation of what the
Earth doth in relation to motion and reſt.
After I had many
and many a time examined with my ſelf the effects and accidents,
partly ſeen and partly underſtood from others, thar are to be
ſerved in the motions of waters: and moreover read and heard
the great vanities produced by many, as the cauſes of thoſe
dents, I have been induced upon no ſlight reaſons to omit theſe

two concluſions (having made withal the neceſſary
ſals) that in caſe the terreſtrial Globe be immoveable, the flux
and reflux of the Sea cannot be natural; and that, in caſe thoſe
motions be conferred upon the ſaid Globe, which have been long
ſince aſſigned to it, it is neceſſary that the Sea be ſubject to
bing and flowing, according to all that which we obſerve to
pen in the ſame.
Nature in ſport
maketh the ebbing
and flowing of the
Sea, to approve the
Earths mobility.
The tide, and
mobility of the
Earth mutually
confirm each other
All terrene
fects, indifferently
confirm the motion
or reſt of the
Earth, except the
ebbing and flowing
of the Sea.
The firſt
ral concluſion of
the impoſſibility of
the ebbing and
flowing the
bility of the
ſtrial Globe being
granted.
SAGR. The Propoſition is very conſiderable, as well for it
ſelf as for what followeth upon the ſame by way of conſequence,
ſo that I ſhall the more intenſly hearken to the explanation and
confirmation of
The knowledge
of the offests
tributes to the
veſtigation of the
cauſes.
SALV. Becauſe in natural queſtions, of which number this
which we have in hand is one, the knowledge of the effects is a
means to guide us to the inveſtigation and diſcovery of the
ſes, and without which we ſhould walk in the dark, nay with
more uncertainty, for that we know not whither we would go,
whereas the blind, at leaſt, know where they deſire to arrive;
fore firſt of all it is neceſſary to know the effects whereof we
quire the cauſes: of which effects you, Sagredus, ought more
abundantly and more certainly to be informed than I am,
