SIMP. This was an accident truly ſtrange, and indeed preter

port in the middle.
ſpem, eſpecially if it were derived from the addition of new ſup
port in the middle.
SALV. From that doubtleſs it did proceed; and the known cauſe
of the Effect removeth the wonder: for the two pieces of the Pillar
being taken from off the Rowlers, one of thoſe bearers on which
one end of the Column had reſted, was by length of time rotten, and
ſunk away; and that in the midſt continuing ſound, and ſtrong,
occaſioned that half the Column lay hollow in the air without any
ſupport at the end; ſo that its own unweildy weight, made it do
that, which it would not have done, if it had reſted only upon the
two firſt Bearers, for as they had ſhrunk away it would have fol
lowed. And here none can think that this would have faln out in
a little Column, though of the ſame ſtone, and of a length anſwe
rable to its thickneſſe, in the very ſame proportion as the thick
neſs, and length of the great Pillar.

SAGR. I am now aſſured of the effect, but do not yet compre
hend the cauſe, how in the augmentation of Matter, the Reſiſtance
and Strength ought not alſo to multiply at the ſame rate. And I
admire at it ſo much the more, in regard I ſee, on the contrary, in
other caſes the ſtrength of Reſiſtance againſt Fraction to encreaſe
much more than the enlargement of the matter encreaſeth. For if
(for example) there be two Nailes faſtned in a Wall, the one twice
asthick as the other, that ſhall bear a weight not only double to this,
but triple, and quadruple.

nor is this effect contrary to the former, though in appearance it
ſeemeth ſo different.

SAGR. Therefore Salviatus, explain unto us theſe Riddles, and
level us theſe Rocks, if you can do it: for indeed I gueſſe this mat
ter of Reſiſtance to be a field repleniſhed with rare, and uſeful Con
templations, and if you be content that this be the ſubject of our
this-daies diſcourſe, it will be to me, and I believe to Simplicius,
very acceptable.
