This paper studies the area between the river Žrnovnica and Jesenice during the Roman Period. The area in question is the western part of Primorska Poljica, which is, again, a part of a wider Poljica region. In pre-Roman times this area was inhabited by the three tribes, the Pituntini, Nerastini and Onastini. Two Roman inscriptions, one found in the village Dubrava, another near Sumpetar, provide information about the area these tribes inhabited. The Romanization of the area betweeen the river Žrnovnica and Jesenice began after 76 BC. It was then that the Romans started settling the wider Salona area. With the arrival of the Roman authorities, a new landscape, that of „villae rusticae“ started appearing on the coast, which was usual for rural areas occupied by Roman settlers. The most important ancient aglomeration is located on the site of St. Martin, right on the seashore. Traces of architecture found there testify to the existence of settlement complexes, with graves found in even more places. Roman families who had their land there mostly belonged to the middle classes, usually veterans, freedmen, merchants and the like. The most famous inhabitant of Pituntium was Lucius Artorius Castus, a Roman officer, whose two inscriptions (CIL III, 1919=8513=12813 and 12791=14224) represent the most important findings for Pituntium up until this date. The cult sphere was dominated by the so-called deities of the Delmatian patheon. The Pituntini, like other Illyrian tribes, especially worshiped Silvanus, a pastoral deity, whose worship remained attested in several places. During this time the Roman road passed through Pituntium, an information that can be found in Roman and eary medieval cartographic sources, Tabula Peutingeriana and the Cosmography of the Annonimous Ravennatis. The late antiquity period brought changes everywhere, including in the area between the river Žrnovnica and Jesenice. The penetration of people from the east and the Byzantine-Gothic conflicts brought unrest to the wider Salona area, which made important stratigic points relevant yet again, namely the prehistoric forts Perunsko and Mutogras. A fragmented inscription mentioning Julius Ausonius, the governer of Dalmatia during late antiquity, was discovered at the Brdine site. To this day, the only reliable early Christian discovery from the Roman Pituntium is the front of a sarcophagus with the inscription „Arca Honorato calegario“ which is now built into the sidewalk in front of the altar of the church of St. Martin. Due to this discovery, there is a very high possibility that there are remains of an early Christian basicila just below today's church, built on the ruins of an ancient property.
