[141] which same thing I have also seen to be the case in the instance of the sculptors’ and painters’ art. For the imitations always fall short of the original models. And those works which are painted or fashioned from models must be much more inferior, as being still further removed from the original. And the stone which is called the magnet is subject to a similar deterioration. For any iron ring which touches it is held by it as firmly as possible, but another which only touches that ring is held less firmly. And the third ring hangs from the second, and the fourth from the third, and the fifth from the fourth, and so on one from another in a long chain, being all held together by one attractive power, but still they are not all supported in the same degree. For those which are suspended at a distance from the original attraction, are held more loosely, because the attractive power is weakened, and is no longer able to bind them in an equal degree.
And the race of mankind appears to be subject to an influence of the same kind, since in men the faculties and distinctive qualities of both body and soul are less vivid and strongly marked in each succeeding generation.
