_Of the Five Orders of Architecture_.
The Five Orders of Architecture are, the _Thuscan_, the _Dorick_, the
_Ionick_, the _Corinthian_, and the _Compound_.
These Orders were Invented to satisfie the Design that might be had of
making Fabricks more or less Massy, and more or less adorn'd, for the
Distinction of these Orders consists in two things, that as the
_Thuscan_ and _Dorick_ Order are more massy and less adorn'd, so the
_Corinthian_ and _Compound_ are Slenderer and Richer, the _Ionick_ holds
the Middle, as well in its Proportions, as its Ornaments, being less
massy and more adorn'd than the _Thuscan_ and the _Dorick_, and more
massy and less adorn'd than the _Compound_ and the _Corinthian_.

Though _Vitruvius_ hath only divided Architecture into Three Orders;
_viz._ The _Dorick_, the _Ionick_ and the _Corinthian_; he doth not for
all that forget to give the Proportions of the _Thuscan_, and speak of
the _Compound_.
