Abstract
Coastal areas of Histria and Dalmatia were very suitable for planting of olive tree and grapevine. During first decades after Roman conquest the whole coastal landscape was divided between colonists and turn into economically prosperous units - villae rusticae often with an oil/wine production.
Those colonists did everything according to an ideal Roman concept well known from Imperial Italy. The complex change of landscape wiped out all remaining rests of "barbarian" agricultural technology but also bring new effective methods, f. e. cultivation of olive tree and grapevine which was not widely know before Roman arrival, same for use of pressing device (both type prelum and screw-type were discovered).
Roman plotting of landscape (centuriatio) is preserved on some localities till today, mostly in vicinity of colonies, which were inhabited mainly by Italian colonists. The small number of original "barbarian" inhabitants after the Roman conquest and also strong tradition of Greek colonization made the transformation much easier.
During the first century of Roman dominance became the coastal areas of Histria and Dalmatia fully romanised. This paper will provide a new comprehensive map of spread of all known Roman sites linked to the production of oil/wine in period from end of 1st century BC till end of 6th century AD in the territory bounded by Tergeste (Trieste, Italy) on the north and by Lissos (Lezhë, Albania) on the south, with localities from today Bosnia and Herzegovina included.
This map clearly disproves old theories about a small scale of oil/wine production in Dalmatia.
