Le dépôt de haches à douille de type armoricain du Hallstatt moyen/final 1 de Trelly (Manche) : interprétations à partir des analyses chimiques élémentaires

Abstract : Discovered in 1998, the Trelly hoard (Manche, France) was discovered through electromagnetic surveys. A quick emergency dig revealed the presence of many artefacts, most of which had been displaced by recent ploughing. The main interest of this small hoard, consisting of about thirty copper-based artefacts, resides in an association of Armorican-type socketed axes with bracelets typical of the Hallstatt D1-D2 period. While this hoard was well-known due to the presentation of several artefacts at the exhibition "Nos ancêtres les Gaulois" held at Nantes in 1999, no analyses had been carried out and the artefacts remained unexploited. In the framework of a new research programme concerning prehistoric copper artefacts and their elementary composition, most of the artefacts from this hoard were the subject of chemical analyses. Many large hoards discovered in Brittany, Normandy and the Channel Islands contained only Armorican-type sock-eted axes. These deposits were said to belong to the final stage of the Bronze Age (Briard, 1965; Rivallain, 1971). New archaeological excavations in Brittany and in Normandy, such as Kergariou, Quimper, Finistère (Menez et al., 2005; Menez & Gomez de Soto, 2006; Gomez de Soto et al., 2009) confirm that this original phenomenon dates from the second period of the First Iron Age. The Trelly hoard also belongs to this period, because of the synchronism of Armorican-type socketed axes and bracelets dated from the middle / late Hallstatt period. This hoard is composed of socketed axes (one of the Tréhou type, one Plurien and eighteen of the Couville type, and two fragments of large axes), five bracelets and fragments of bracelets (one open bracelet decorated with transverse incisions, one open massive bracelet with a sub-rectangular section resembling a gear-wheel, a fragment of an open and massive boss bracelet with a plano-convex section, a fragment of a massive bracelet with a plano-convex section decorated with four transverse incisions, a closed and massive bracelet with a circular section), a fragment of a shank.
