“And though variety and novelty may please everybody, one
should not, however, do anything that is contrary to the laws of
this art, and contrary to what reason makes obvious; so we can
see that the ancients also made variations, but they never
departed from certain universal and essential rules of this art, as
we shall see in my book of antiquities.”
