It was, perhaps, Greek influence which brought in a stricter use of the rectangle and a greater care for regular planning.
It may be asked how all this applies to the planning of towns.

We possess certainly no such clear evidence with respect to towns as with respect to divisions agrarian or military.

But the town-plans which we shall meet in the following chapters show very much the same outlines as those of the camp or of the farm plots.

They are based on the same essential element of two straight lines crossing at right angles in the centre of a (usually) square or oblong plot.

This is an element which does not occur, at least in quite the same form, at Priene or in other Greek towns of which we know the plans, and it may well be called Italian.
