Our research on spatially bounded Iron Age enclosure of the Viereckschanze type in southern Bohemia made it possible to distinguish the anthropogenic influence of the Iron Age from modern human activities. We collected over 456 samples from 200 cores to a depth of up to one metre. Samples were measured using pXRF to determine the content of the following elements: Al, Si, P, K, Ca, Ti, Mn, Fe, Cu, Zn, As, Rb, Sr, Zr, Pb, and LE – ‘light elements’). Subsequent isometric log-transformation of ppm elemental contents and PCA allowed to distinguish the prehistoric anthropogenic influence from the current modern one. The result of the analysis is as follows: 1) the P signal typical for archaeological settlements was found mainly outside of the enclosure; 2) the conventional anthropogenic signal from the inside of the enclosure was only represented by Mn; 3) other elements related to possible anthropogenic activities were revealed only after applying statistical analysis (As, Pb, Zn, Cu); 4) the unusual manifestation of Si and Ti was connected to the archaeological contexts. The combination of these results (Cu, Zn, Pb) and magnetic measurements revealed places of metallurgical activity inside Viereckschanze. It is certain that the site was not only a place of residential activity, but also of production activity. Viereckschanze was only occupied for a short period of time.The presented abstract is adapted from the article published in Catena in 2022.

Ancient brass (aurichalcum) was a valued commodity in the Antiquity, notably because of its gold-like appearance. After mastering brass fabrication using the cementation procedure in the 1st century BC in the Mediterranean, this material became widely used by the Romans for coins, jewellery and other objects. Because of its visual qualities, it is believed that since this period, brass played an important role in diplomatic and economic contacts with indigenous communities, notably Celtic and Germanic tribes north of Danube and west of Rhine. To test this hypothesis, we performed for the first time the archaeometric and advanced statistical multivariate analysis of a suite of late Iron Age and Early Roman period (1st century BC – 1st century AD) brass and other copper-alloy objects from the territory of Bohemia to constrain their provenance. The new results for brass objects from this early phase of the massive occurrence of Roman aurichalcum in the Barbarian territories point to the ore deposits in the western Mediterranean or the Massif Central area in Gaul, consistent with historical events. These new findings underscore the great economic and political importance of the new and rich mineral resources in the Transalpine Gaul acquired due to Caesar's military campaigns

Článek představuje soubor předmětů nalezený při úpatí nápadného kamenného útvaru poblíž Stebna, okr. Louny, a interpretovaný jako rituální depot ze stupně LT B1/B2. Z tohoto období nejsou v okolí místa nálezu známy žádné další lokality. Soubor obsahuje vedle keramické misky a souboru laténského ženského kruhového šperku i jedinečnou importovanou bronzovou mísu středoitalského původu. Rozbor depotu a provedená makrozbytková a palynologická analýza umožňují klást si otázky o vztahu střední Evropy a Středomoří, o lidské přítomnosti v regionu a o rituálních aktivitách v době laténské.
