We have deemed it advisable to sanction by legal authority that most excellent and equitable rule established by Our Father, of eternal glory (as it was not inserted in the body of legislation) ; namely, how much space from the field of a neighbor should be left by those who intend to construct houses upon cultivated land or in vineyards, for the purpose of devoting the same to public uses? Therefore, We decree that where anyone desires to erect a new building in a field which is ready to be sowed, he shall, if the size of the place permits this to be done, be obliged to build it, in accordance with the said constitution, two arrowshots from the boundary of the neighboring land, or one arrowshot, if the distance between the two tracts is too small to admit of this; and, moreover, he shall not be permitted to erect a new structure within the limits of the space above mentioned; the reason for which provision is so manifest that there is no need to mention it, for the nearer the building is to the land of another, the more damage it is liable to cause to the crops.
