ART. III.
Of the Five Orders of Architecture.
HE 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.

Chap. 7. 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.
ART. IV.
Of Things that are Common to several Orders.
Before we treat of the Differences of these Five Orders, it would be proper to speak of those Things that are common to several Orders; as are the Steps, Pedestals, the Diminution of Pillars, their Channelling, Piedements, Cornices, and Acroteres.
