The Imperial cult is the most original element of Roman religion and the most important
expression of the system of honors for the 'princeps' and the other members of the
'domus Augusta'. The cult of the 'divi' had different shapes and Rome stood out from the rest of Italy and Empire: in Rome, the mechanism of worship was characterized by a
variety of places, forms, and situations. However in the 'Urbs' the evaluation of the urban
and monumental impact of this fundamental religious innovation is not always evident,
and an investigation is required to deal with the lack of correlation between archaeological
data and topographical documents about urban sanctuaries.
