(1) How does Mann dispel Western concepts about pre-Columbian America?
The arrival of the Mayflower in Cape Cod signs the beginning of the crumbling of an entire civilization. Europeans brought to America a technological progress unknown to a still rural and sterile society which was still living without firearms and vessels that will soon have to discover the bloody price of innovations. Without a doubt and halt the power of the progress from overseas completely alienated a society of millions of peaceful souls who often tried to fight to defend their territory and their life. The Indians had no strategies nor the army with horses and guns used by Europeans nor were familiar to quarantines to protect and cure themselves from of all the multiples plagues shoveled on them. The arrival of innovations in America from the capitalist mind of power and conquer accomplished only to subdue, alienate and annihilate a civilization which was prospering on its terms.
(2) Why was native agricultural technology an important legacy to the rest of the world?
After the arrival of Columbus in the Americas, the clash of the two civilizations left signs and consequences of both cultures. The Europeans were technological advantaged compared with the Indians, who had no idea on what was possible accomplish with steel, iron and other sorts of metals already widely used from the overseas’ friends. However, Indians, on the other hand, were masters in agriculture like nobody else in the rest of Europe and that is why most of the produce – cultivated nowadays in Europe and the rest of the world – came straight from the Indians’ agriculture developments. One among the many foods to mention is the corn which was cultivated by the Indians in different growing conditions, and that is why was possible to spread it across the globe.
Pozzolana’s discovery may be thought of one of the extraordinary steps into the progress of ancient constructions product of concrete. Although its development is typically attributed to the Romans, its use is seen in earlier works throughout the X sec. by Phoenicians and Israelites largely in hydraulic constructions.
In effect, the potable water tanks engineered by King Salomon in Jerusalem were protected by an external material made of the Pozzolana lime. However, the role of the Romans is vital because they utilized pozzolana rationally and perpetually, subbing the natural sand with this Pulvis Puteolana The Colosseum , typical of the area around Pozzuoli (that is additional the origin of the name itself Pozzolana).
The Romans were able to grasp the peculiar consistency of pozzolana, this volcanic ashes that combined with lime would create a new texture able to become hard underwater and thus be useful in constructions designed to carry/conduct water itself. The Romans discovered that pozzolana was invariably present in areas around inactive volcanos not simply in Italy but throughout the emperors and its ability to be combined with baked clay in different forms – such as tiles, bricks. In most of their works, the Romans utilized concrete to fill the spaces between bricks or stones.
Two major Romans’ constructions made of concrete are incredibly noted because they are still intact and which proves the durability of the used materials during its completion: the Pont Du Guard in Nimes, France, and the Pantheon in Rome which are respectively a hydraulic engineering work and an architectonic construction.
The Pont Du Guard in France was a part of a water conduit about 50 Km long that was carrying water from the city of Uzes to Nimes.
The Pantheon in Rome, it is not only an architectonic masterpiece well-known worldwide for its perfection and wonder but also because it is one among the oldest constructions left to us today to admire from the Romans’ culture.
The Blombos’ cave takes archeologists and scientists back on the analysis of the evolution of the cognitive capabilities of the Homo Sapiens to re-evaluate the information used to create the same theory that leads to us.
The Blombos’s cave is a prehistoric site of the South Africa State carved into a limestone cliff that overlooks the Indian Ocean. The cave was frequented used, intermittently, by Stone Age men for about 140,000 years and it became famous in 1993 when Dr. Henshilwood discovered some important stone artifacts. These artifacts were symmetrical spearheads about 20,000 years old. Inside the cave, were also found some shells used as containers to mix a base of ocher color, dated about 100,000 years ago. In the shells, it was found a veneer of bright red powder, dried remains of a colorful mixture made by mixing red ochre, seal bones, coal, quartzite, and water. Along with the shells, the researchers also found animal bones probably used to collect color.
The artifacts discovered in the cave shed new light on the evolution of cognitive abilities of our species occurred long before then we have theorized. The search for the concept of beauty – like art, music, sculpture, paint – has a new historically Genesis that need to be readdressed.
