It was not only on the staves of office that the men of the Stone age exercised their talent. Many and varied are the subjects which have been found engraved on plaques of ivory or on stone, and incised on bears’ teeth or on stag horn. We represent one forming the hilt of a dagger (Fig. 36), and another representing a bear with the convex forehead, characteristic of the species, engraved on a piece of schist (Fig. 37), and a mammoth engraved on an ivory plaque with its long mane, trunk, and curved tusks (Fig. 38). The artist who depicted these animals with such faithful exactitude evidently lived amongst them. The first discovery of this kind was made by Joly-Leterme in the Chaffaud Cave (Vienna); it was a reindeer bone on which two stags were represented.24
