A system of town-planning that is so distinctive and so widely used might reasonably have created a series of building-laws sanctioning or modifying it.

This did not occur.

Neither the lawyers nor even the land-surveyors, the so-called Gromatici, tell us of any legal rules relative to town-planning as distinct from surveying in general.

The surveyors, in particular, are much more concerned with the soil of the province and its 'limitation' and 'centuriation', than with the arrangements of any individual town, and, whatever their value for extramural boundaries,[116] throw no light on streets and 'insulae'.
