Aux sources d'un style céramique original. Des pots à décor couvrant imprimé ou modelé, une spécificité du territoire sénon au 5e siècle av. notre ère ?

The paper is focused on impressed or modelled covering decorations well represented on pottery in the heart of the Paris Basin during the Second Iron Age. After a phase of emergence in the western Hallstattian province, a concentration of these decorations can be highlighted in the second half of the 5^th century in the middle valley of the Seine especially between the confluence of the Seine and the Aube and the confluence of the Seine and the Yonne. Their wider diffusion mainly northwards occurs from the 4^th century. The discussion focuses on both the characterization of this phenomenon and its delimitation with a more specific reflection on a possible link at the time of the first flourishing with a 'Senon' cultural space.
