Abstract EN:

A topographical repertory of the ancient coins found out in the area of the civitas pictonum (or first poitiers diocese) has been drawn up, as completely as possible. On the basis of it, an historical analysis of monetary facts regarding this wide area, which included more than three french departments of the present day, is proposed here, as well in the celtic independance period as under the roman domination till the beginning of 5th century. Main supplying rythms having been defined firstly, the circulation of money enables to understand, according to statistics, the great political and economical gaps having been holding sway through the country - roman conquest, crisis and inflations of third and fourth centuries - optimal phases of celtic and roman high empire periods. It also enables to demar- cate various trading or hoarding areas, drawing them on maps, and to pro- pose a first social history essay of the pictonian "nation" then civitas discerning in particular the evolution of the relationship between town- vici-country all the ancient civilization long and making use of coinage as one of the best revealing facts of the successive processes of celti- zation, then romanization. A privileged place has been given to the chief town of civitas, lemonum, the historical topography of which having been notably enriched by setting found coins in series. A great emphasis has been placed lastly on the risks concerning the chronological use of coins discovered when digging the land, considering the frequent longevity of this kind of artefact and on the necessity of a tigh collaboration between numismatists and ar- chaeologists in order to avoid any overinterpretations and mistakes.
