This perfect, 'as made' LARGE prismatic blade knife was made Pre-Columbian Aztec Indians of Central America. Blades like these were used in a variety of tools and weapons, feared for their incredible sharpness when incorporated in weapons of war. This exquisite example is complete with no damage and shows perfect parallel sides indicating it was made by a highly skilled obsidian worker. The translucent obsidian glows when held to the light. A natural partial fissure appears in the photos as if it was a repair but it is an anomaly of the volcanic glass and does not go all the way through to the surface as a repair would. Obsidian blades like this were also commonly used in ritual blood-letting sacrifices often performed in individual and group rituals of the Aztecs. Aztec noble classes wore obsidian jewelry and Aztec priests polished the obsidian to a mirror-like sheen and claimed to divine the future with it. They believed obsidian, like everything in nature, had a spirit.
Mineral and sediment can be seen deep in flake scars which are indicators ONLY found in AUTHENTIC specimens such as this. Caution must be applied in acquiring ancient obsidian artifacts because the stone does not patinate on the surface like other lithic types.
Core-struck obsidian prismatic blades were a hallmark industry of the Aztecs. The blades were struck from a carefully prepared blade core stood on its end. The top was hit downward to flake off long, rectangular strips of the stone. The core was turned around and blades were struck off around the entire circumference of the standing core. As the core became used up, the blades began showing a curve in the end as the base of the core became smaller and more tapered.
Finding Pre-Columbian prismatic obsidian blades in a COMPLETE UNBROKEN state is VERY RARE. Obsidian was prized by the ancient Pre-Columbian Indians and even today, it is still used in modern medicine for scalpel blades as obsidian can flake to an edge one molecule thick, thereby attaining a level of sharpness impossible to achieve with a steel scalpel. As a matter of fact, aside from using lasers in modern surgery, the preferred scalpel is one from obsidian. Because of its sharpness, obsidian leaves less of a scar and does less tissue damage than a scalpel or knife made of any other substance known to Man. Obsidian is 15 times sharper than surgical steel, It’s no wonder that obsidian became a valuable tool in medicine and warfare when you consider that at an obsidian scalpel can rival diamond in the fineness of its edge. Common household razor blade edges are 100 times thicker than the edge of struck obsidian!
While many ancient civilizations remain a mystery, little can be left to conjecture when it comes to the details of the Aztec way of life. An extensive and detailed collection of written and pictorial records exist for us today called CODICES (CODEX if singular) were produced before Spanish contact by the native tribes themselves, and afterwards during the Colonial period. These codices were created by the Aztecs in pictorial form, as well as by other indigenous tribal sources, all of which had no written language. Colonial era codices exist in greater number with roughly 500 separate codices known, showing extensive pictograms as well as being written in Spanish, Latin and in the original Nahuatl language.
The origin of the Aztec (Azteca) Empire is legendary. Aztec codices record that they began their wandering journey in 1100 A.D. emerging from their former homeland called Aztlan or "place of the herons", an island in a lake where men went out to fish from boats. The exact location of this region is not known but other than it was northwest of present-day Mexico City, the former center of the Aztec empire, but how far, it is a mystery.
The Aztecas believed they were guided by a blood-thirsty deity they called Huitzilopochtli who communicated to them through four priest-chieftains called teomama. Their god called upon them for his insatiable thirst for human blood and sacrifice. As they migrated south, every indigenous Indian tribe they encountered along the way abhorred the Azteca, as they were known, as they were reviled and scorned for their violent and barbaric ways. During their migration, Huitzilopochtli gave a message to his people that their new identity would no longer be known as Azteca but as Mexica. In around 1325 A.D., as they were fleeing an altercation with the Culhuacans, they were driven to a marsh. Their god Huitzilopochtli consoled them that evening and said he would end their wandering and told them to look for a sign that he will give them that will signify their new homeland which will be "the place of the cactus and the eagle I now name Tenochtitlan". They next day they witnessed an eagle resting on a prickly pear cactus which they interpreted to be the sign they were hoping for.
This marsh, Lake Texcoco, would later become a vast canal-laced highly advanced, super city of stone pyramids and temples known as Tenochtitlan. With a population that grew to an estimated 200,000 people (three times the largest city of Spain at the time!) this became the center of the most powerful and militaristic empire of Mesoamerica - home of the Aztecs. Today, we classify their reign as occupying the Late Post Classic Period from 1250 - 1521 A.D.
The success and rise of the Aztec empire was largely attributed to their dominance through intimidation of their surrounding neighbors from whom they extracted resources from. The effect of their extreme militarism and brutality on their enemies brought a large region of peoples into submission. The highly advanced and complex Aztec social structure, as well as legal system, kept their growth intact and the society orderly. They formed an alliance with the Texcoco and Tlacopan tribes and in 1428 A.D., they defeated the Tepaneca. This triple alliance established a great empire that was predominantly ruled from Tenochtitlan. At its peak, this empire included a large, diverse group of people and spanned an area from the entire Central Mexico region south, into northern Guatemala.
