This paper deals with a collection of nineteen bronze statuettes that take the shape of a small plate from which only legs, arms and head protrude in relief. The main interest of this corpus lies in the fact that these pieces of work, of a kind generally used to portray dedicants, present a new iconographic theme. Indeed, eighteen of them show shackled figures, probably prisoners. A comparative study suggests that this corpus may be interpreted as a set of small statuettes offered in thanksgiving, dating from the end of the first millennium BC and the beginning of the Christian era.
