Bone, which includes teeth, presented to savage man a hard and durable material for improving his coarse wooden weapons. Teledamus or Telegonus, son of Circe and founder of Tusculum[74] and Præneste, according to tradition slew his father, Ulysses, with a lance-head of fish bone—_aculeum marinæ belluæ_. The teeth of the Squalus and other _gigantum ossa_ or megatherian remains supplied points for the earliest projectiles, and added piercing power to the blow of the club. That a Bone Age may be traced throughout the world,[75] and that the phrase a ‘bone- and stone-using people’ is correct, was proved by the Weltausstellung of Vienna (1873), whose splendid collection found an able describer in Prof. A. Woldrich.[76] The caves of venerable Moustier (Département Dordogne), of Belgium, and of Lherm (Département Arriège) contributed many jawbones of the cave bear (_Ursus spelæus_); the ascending ramus of the inferior maxilla had been cut away to make a convenient grip, and the strong corner-teeth formed an implement or an instrument, a tool or a weapon. The caves of Peggau in Steiermark (Styria), of Palkau in Moravia, and the Pfahlbauten[77] or Pile-villages of Olmütz, produced a number of bone articles and remnants of the cave bear. These rude implements remind us of the weapon used to such good effect by the Biblical Samson, the Hebrew type of Hercules, the strong man, the slayer of monsters, and the Sun-god (Shamsún).[78] [Illustration: FIG. 17.—DEER-HORN ARROW-HEAD.
