[This article-review, which had been orderd by the editor of a famous classical studies' revue, was rejected as too long on July 10, 1992 by the same editor who invited the author to reduce it. The author did not reduce it, and the article was not ever published. Here we are presenting it in its primal draft, that is not updated, because in our opinion the validity of its contents endures intact.]

We are sorry, but at present the English translation of this article is not available.
