The Grecian square measures were the plethron, or acre, containing 1444, as some say, or as others report, 10,000 square feet; the aroura, which was half the plethron. The aroura of the Egyptians was the square of 100 cubits.

The Roman square measure was the jugerum, which, like their libra and their as, was divided into twelve parts called unciæ, as the following table shows:—

	Unciæ.		Square feet.	Scruples.	English roods.	Square poles.	Square feet.

N.B. The Actus Major was 14,400 square feet, equal to a Semis. The Clima was 3600 square feet, equal to a sescuncia, or an uncia and a half, and the actus minimus was equal to a sextans.
