"They carried on their improvements in drawing, painting, architecture, sculpture, &c. till they became the wonders of the world; especially after the Asiaticks and Egyptians (who had formerly been the teachers of the Grecians) had, in process of time and by the havock of war, lost all the excellency in sciences and arts; for which all other nations were afterwards obliged to the Grecians, without being able so much as to imitate them. "For when the Romans had conquered Greece and Asia, and had brought to Rome the best paintings and the finest artists, we don't find they discovered the great key of knowledge, the Analogy I am now speaking of, but their best performances were conducted by Grecian artists, who it seems cared not to communicate their secret of the Analogy; because either they intended to be necessary at Rome, by keeping the secret among themselves, or else the Romans, who principally affected universal dominion, were not curious enough to search after the secret, not knowing the importance of it, nor understanding that, without it, they could never attain to the excellency of the Grecians: though nevertheless it must be owned that the Romans used well the proportions, which the Grecians long before had reduced to certain fixed rules according to their ancient Analogy; and the Romans could arrive at the happy use of the proportions, without comprehending the Analogy itself." This account agrees with what is constantly observed in Italy, where the Greek, and Roman work, both in medals and statues, are as distinguishable as the characters of the two languages. As the preface had thus been of service to me, I was in hopes from the title of the book (and the assurance of the translator, that the author had by his great learning discovered the secret of the ancients) to have met with something there that might have assisted, or confirmed the scheme I had in hand; but was much disappointed in finding nothing of that sort, and no explanation, or even after-mention of what at first agreeably alarmed me, the word _Analogy_. I have given the reader a specimen, in his own words, how far the author has discovered this grand secret of the ancients, or _great key of knowledge_, as the translator calls it.
