Traceology suggests an unexpected use of antler cheekpieces from the Early Iron Age site at Gzin, Poland

Abstract Archaeological data confirm the widespread use of horse tack throughout the North European Bronze Age and the succeeding Hallstatt period in an inventory that included metal cheekpieces, phalerae, rein-knobs and other horse-related accessories. Similar usage has been assumed in the region of northern Poland, which has also furnished evidence for the use of horse gear accessories made of antler. This paper reports the results of traceological, isotopic and experimental research on three antler cheekpieces found at the Early Iron Age stronghold of Gzin in northern Poland and relates them further with archaeological and ethnographic patterns of horse exploitation. The results indicate that the artefacts from Gzin have rare comparanda and are isotopically consistent with the δ 18 O w range of the site location, which can both be taken as evidence of their local origin. Moreover, traceological and experimental evidence from this study places the function and use of the analysed objects into a new light, undermining their use for horseback riding and suggesting that they were employed as cheekpiece coverings. Combined with the ethnographic record, ceramic iconography and archaeolinguistics, our findings fuel a discussion of deer valorisation during the Lusatian period in Poland, showing that the cheekpieces from Gzin may have served as elements of deer headgear.
