ART. II.
Of the Vestibulum or Entry.
HE Houses of the Ancients had Great and Magnificent Entries, they were sometimes 15 Perches long and 9 broad, and they were supported upon two ranks of Pillars, which made a Wing on each Side, the Proportion of their breadth and length was taken three Ways. The first was, when having divided the length into 5, 3 were allowed for the breadth. The second was, when having divided it into 3, 2 were allowed for the breadth. The third was, when having made an Equilateral Square, the Diagonal of this Square was taken for the length, and the Side for the breadth.
The height was equal to the length, taken from the Pavement below, to the bottom of the Plat-Fonds or Flat-Roof, which was hollowed on the other side the Beams, the seventh part of the whole height.
The Proportion that the Alley which was in the middle between the Pillars, had with the Wings, was different according to the Magnitude of the Vestibule or Entry, for the greater they were or the lesser, the Wings had a proportionable breadth with the Alley in the middle; So that if the Vestibule or Entry was 100 Foot long, the Wings had only for their breadth the 50th. part of the length; and when it was but 30 Foot long, they had only the 3d. part.
