![]() ![]() The beginning of the Neolithic, the retreat of the last glaciers, and the invention of food crops, involving agriculture and animal domestication, were more or less contemporary events. The term Neolithic Period, or New Stone Age, defines the second period, at the beginning of which ground and usually polished rock tools, notably axes, came into widespread use after the adoption of a new technique of stoneworking. Bone was a particularly useful material, for its toughness made feasible barbed fishhooks, eyed needles, and small leatherworking awls. These three materials, all softer than rock but nevertheless intractable, could not be worked successfully without the aid of harder rock tools, such as serrated blades and gravers, or burins, small scrapers with either pointed or narrow, chisel-like ends. The later Paleolithic was also an era of wood, horn ( antler), and bone. The Paleolithic Period, or Old Stone Age, endured until about 10,000 years ago and was characterized by tools of chipped stone, cutting tools with rough and pock-marked surfaces and generally serrated cutting edges. The Stone Age is divided into two contrasting periods: the Old Stone Age, a long era of stagnation and the New Stone Age, a brief period of swift progress.

Typical of representations in Aztec art of eagle-warriors the figure wears a loincloth or maxtlatl, a winged cloak decorated with white stars and his head protrudes from a beaked headdress, also decorated with stars, representing the head of a bird of prey. Interestingly, the figure is himself clutching the knife with both hands. ![]() The mosaic tesserae are attached using pine and copal resin which is also used in places as a decorative inlay. The lips and gums of the smiling warrior are dramatically picked out using orange-red shell. Other details picked out in malachite, conch and mother-of-pearl include jewellery such as bracelets, anklets, a chest decoration, and a nose ornament. Fine details such as eyes, teeth and fingernails are rendered using even smaller tesserae of dark green malachite and three different shell types: white conch ( Strombus sp.), thorny oyster ( Spondylus princeps) and mother-of-pearl ( Pinctada mazatlantica). The figure is covered in mosaic made from small pieces of pale blue turquoise. The handle of the knife has been carved to resemble a crouching figure who wears the ritual costume of an Aztec eagle-warrior or cuauhtliocelotl, one of the most senior Aztec military ranks and also translated as eagle-jaguar.
