Astronomical Orientations in the Roman Centuriation of Tunisia

Abstract

The centuriation, also known as limitation, was the method used by the Roman surveyors for subdividing the land in a regular chessboard of fields, created by a grid made of parallel and perpendicular roads and canals. Here we discuss the limitation of Tunisia and the existence of some astronomical orientations of the grids, that is, orientations towards the direction of the sunrise on solstices or moonrise on lunar standstills.
