In this paper will be discussed the use of ruminant metapodial bones for making figurines during Neolithic in the Old world. The context of these objects is either settlements or graves. Though, their value is clear, but remains quite mysterious. In the publication they often considered as idols. Many examples of these objects can be cited, either from archaeological or ethnographical contexts. Ruminant metapodial is a frequent support for making dolls in Africa. After having depicted the characteristics of those we know in Neolithic, we will discuss the fonction of such objects, on the basis of use-wear and ethnographical comparison.
