This dissertation presents four methodological case studies that
elaborate on the results of two field survey projects (the Astura and
Nettuno surveys) that were carried out by the Groningen Institute of
Archaeology (GIA). The case studies aim at investigating biasing factors
that limit the analytical and comparative value of data from
archaeological survey in general using these two projects as a suitable
testing ground. Both surveys, carried out between 2003 and 2005, fell
within the ambit of the Pontine Region Project (PRP), a long-term
research program aimed at the diachronic archaeological investigation of
the various landscape units forming this region. They covered two
contiguous areas, situated on the Tyrrhenian seaboard, approximately 60
kilometres south of Rome. The study area comprises the communal area of
the modern town of Nettuno, as well as the lower valleys of the Astura
and Moscarello rivers (see fig. 0.1).2 As such it incorporates parts of
the hinterland of the ancient towns of Antium and Satricum. In
chronological terms this dissertation considers a time-span of 1300
years, from the 6th century BC to the 7th century AD.
