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 balls 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.
The reading passage says some reason about the carved stone balls which found around the scotland 4000 years ago .however the lecture challenges that reasons.
first, the lecturer says that the reading's claim about the hunting and fighiting purpose of the balls is wrong. she says that other kind of historical weapons like arrows ,are always damaged by the time and never they might be compeletly presarved. But the balls are not cracked and destroyed . but they are at a good situation.
the speaker also refutes the reading claim that this balls were used for weighting or measurement. according to the lecture, there have been some different kind of balls in that time , like sand balls or green balls. this different kind of balls had spacial density and they could not be the instrument of meaturement because the same size balls might had different weight.
finally, the lecture is not convienced that this stone balls were used for the social purpose and the person situation in the society.she claims that usually important persons in the past buried on their position while all of the balls are found in the tunes or caraves.
so the speaker says that the reading are not convienced her about carved stone balls .
