The Latin monetiform tessera from Oiasso, Irun (Guipuzcoa, Spain)
The present research work has as object of study a tessera monetiform with a representationof a dextrarum iunctio and the epigraph AD FID IBN on the obverse, and SPCPTEZ on the reverse. Found in Irun and deposited at the Roman Museum Oiasso of thiscity from Gipuzkoa, no one has explicitly pronounced on it so far nor has it been edited.The lack of parallels precludes the resolving of the abbreviations and, therefore, the fullunderstanding of the epigraph. However, we propose the hypotheses that this tesserashows a possible pact in relation to a population transfer for working activities in themining district of Oiasso, as well as a tentative but uncertain reading. Its chronologyis not less problematic, though a date between the late Republican period and the firstyears of Augustus is acceptable.
