As is well known, several Roman sources report on the existence of a town foundation ritual,
inherited from the Etruscans, which allegedly included astronomical references. However, the
possible existence of astronomical orientations in the layout of Roman towns has never been
tackled in a systematic way. As a first step in this direction, the orientation of virtually all
Roman towns in Italy (38 cities) is studied here. Non-random orientation patterns emerge
from these data, aiming at further research in this field.
It's a paper. I have not read it.
