As is widely recognized, the study of the metallic elements of ancient dress - the only part that has reached us - allows much better than other investigations, except for those relating to the mortal remains of the human body, to know the belonging of people to certain groups and consequently their mobility. For this reason some distribution maps of the different types have been prepared for a long time - and they are constantly evolving - but they must rely, to base their validity, on identifying the points of greatest concentration or better the manufacturing centres. Sorin Cociş has become a true master in this field.
Finally we have this long awaited book in our hands. The work written by Sorin Cociş comes after a wide and prolonged series of studies, developed for over thirty-five years, dedicated to the Romanian fibulae and their dissemination, even beyond the borders of the current state, - according to a tradition coming directly from the great nineteenth-century scholars - of the types mainly attested in that territory. In this work, remarkable for its breadth of setting, a vast area is examined: it goes from Raetia (part of Switzerland and today South-East Germany) to Dacia, crossing the Noricum and Pannonia, or current Austria, Hungary and Serbia. The author's point of view is clear: he want to analyze, by comparison, the areas from which merchants, soldiers and inhabitants of Roman Dacia probably came, bringing with them besides countless other things models for dress and consequently the fibulae, immediately locally produced. The result is a very interesting picture in this respect of the middle and lower Danubian area. The chronological range is obviously that of the life of the Roman province of Dacia, that is, from Trajan to Aurelian. This fact alone is enough to point out the particular position of this work that overcomes the regional syntheses - now fundamental not only for the Balkan area, even if included within the state boundaries - and obviously the catalogues dedicated to individual cities.
