Each, indeed, of the subjects of the two immediately preceding paragraphs, is worthy of a volume; for the first is as essential to all judgment of existing beauty at the instant of its being before us, as the second is to all prescience of what beauty will very soon be--to all who have no love for a leap in the dark. I add to this chapter but a few words on the very _different organization of the head and face_, and the very different mind, of the Greeks and Romans. Whoever, for the purpose of comparing the heads of these two nations, may walk into the British Museum, will be struck with the difference between them. The forehead is almost always rather narrow, and rather high, in the most illustrious Greeks; and this could not so uniformly have been so represented, in sculpture, unless it had been so also in fact. This is verified, in the third room of the Townley collection, by the heads of Homer, Hippocrates, Epicurus, Pericles, &c.--by the almost universal conformation of Greek heads, to which there are but few exceptions: Sophocles, in this room, and Demosthenes, in the eleventh, are rather broader. On the contrary, the forehead, the face, the jaws, are excessively broad, and the cranium is depressed and low, in the Romans--in Severus, Nero, Caracalla, &c., in the sixth room, and in Tiberius and Augustus, in the eleventh; nor is this owing to the circumstance that these generally were men degraded in feeling or intellect, for nearly the same configuration is found in Trajan, Hadrian, &c., in the fourth, sixth, and other rooms. The faces of the Romans are not less ugly than their heads; and those of their women are absolutely detestable, as may be seen in Faustina, Plautilla, Sabina, Domitia, &c., in the sixth of these rooms. If farther illustration of this be wanting, it may be found in the circumstance that, while the Greeks preferred the rather high forehead, and invented the ideal one, the Romans, on the contrary, preferred a little forehead and united eyebrows. Ovid assures us that the women of his time painted their eyebrows in such a manner, that they might appear to form only one. In the work so often referred to, I have shown that the intensity of functions is as the length of their organs, and the permanence of functions as the breadth of their organs. No truth can be better illustrated than this is, in the organization and the faculties of the Greeks and Romans. With the higher and larger head of the Greeks was united an intensity of genius, which no other people has yet rivalled; and with the broader head of the Romans, a perseverance, equally obstinate and unfeeling, which has been similarly unrivalled.
