Carved stone balls are a curious type of artifact found at a number of locations in Scotland. They date from the late Neolithic period, around 4,000 years ago. They are round in shape; they were carved from several types of stone; most are about 70 mm in diameter; and many are ornamented to some degree. Archaeologists do not agree about their purpose and meaning, but there are several theories.
One theory is that the carved stone balls were weapons used in hunting or fighting. Some of the stone balls have been found with holes in them, and many have grooves on the surface. It is possible that a cord was strung through the holes or laid in the grooves around the ball. Holding the stone ball at the end of the cord would have allowed a person to swing it around or throw it.
A second theory is that the carved stone balls were used as part of a primitive system of weights and measures. The fact that they are so nearly uniform in size—at 70 mm in diameter—suggests that the balls were interchangeable and represented some standard unit of measure. They could have been used as standard weights to measure quantities of grain or other food, or anything that needed to be measured by weight on a balance or scale for the purpose of trade.
A third theory is that the carved stone balls served a social purpose as opposed to a practical or utilitarian one. This view is supported by the fact that many stone balls have elaborate designs. The elaborate carving suggests that the stones may have marked the important social status of their owners.
Both the reading passage and the lecture discuss about the purposes of using carved stones. While the author of the article presents three theories on different forms of usage of the stone balls, the lecturer contradicts each of these theories.
First of all, the passage suggest that the carved stones were utilized as weapons for hunting and fighting. Some of them also contained holes, through which a cord was strung and used to throw them. However, the listening argues that no cracks were found on the weapons such as arrow head of that time. If the stone balls had used as weapons, they would have cracks on the surfaces. But the surfaces were preserved and no damages have been discovered.
Secondly, the reading mentions that the stones were used as standard weights, since they were uniform in size. In contrast, the professor in the listening contends that the stones could not be used as standard for measuring weights as they were achieved from different source and had different densities. Some were heavier than others and they couldn't be similar. Just like a handful of feather is not similar to a handful of rock.
Finally, the last theory claims that the carved stones were the symbol of social status. The meticulous design of the stones are the representation of the status of the owner. Nonetheless, the lecture asserts that they were not used as the representation of social status because many of them had simple design, which can not be used as a representation of status. If they had exploited as a form of social status, they would have found on the grave of high rank people. But they were not found in the grave or tomb.
In conclusion, based on the reasons mentioned above, the lecture argues that the theories of the passage is not as tenable as it stands.
