Surveyors went out beforehand to lay out the site; their base-point was the crossing of the main streets (cardo and decumanus); from this were laid out the rectangular blocks of the main town and sometimes the allotments outside it, called centuriae.7 These were ordinarily units of two hundred jugera, their corners marked by boundary-stones, a number of which survive
So they measured out and marked where they would settle? that seems fair for both sides when it came to lands.
