Although these feeble beginnings of criminal anthropology received the sanction of the highest scientific authorities, as well as of the people, and later on a mediæval law declared that if two persons fell under suspicion of crime the uglier or more deformed was to be regarded as more probably guilty, they were not universally admitted, and some, like Pliny, regarded it as absurd that the outward form could indicate the inward disposition. Whatever art or science there was in the matter was left, then and long after, to the physiognomists, of whom Polemon may be taken as a distinguished example, and these were ready to supply the most elaborate physical signs to correspond to any vicious or criminal disposition. Polemon wrote of the criminal that he was of pallid complexion, with long hair, large ears, and small eyes, and he proceeded to give the characteristics of various classes of criminals, his observations often showing keen insight. This pseudo-science was passed on from physiognomist to physiognomist, usually with added absurdities, until in the sixteenth century we reach the Neapolitan Dalla Porta, at once the greatest (and except Lavater the last) of the physiognomists of the old school and the first of the new. He treated judicial astrology with contempt, and at the same time wrote a treatise of celestial physiognomy; he gathered up all that his predecessors had done, and at the same time laid the foundations of a more scientific treatment. Passing by Lavater, with his fine intuition and genial humanity, which formed, however, no epoch in the scientific study of criminal anthropology, at the beginning of the present century we reach Gall, a very great figure in the history of science, and the representative of the most important moment in the development of our knowledge of the brain. Before speaking of Gall, however, it is necessary to give a word, in passing, to Grohmann, who slightly preceded him, and who anticipated many of the conclusions relative to facial and cranial characteristics reached by modern criminal anthropologists. Thus, in 1820, he wrote:--“I have often been impressed in criminals, and especially in those of defective development, by the prominent ears, the shape of the cranium, the projecting cheek-bones, the large lower jaws, the deeply-placed eyes, the shifty, animal-like gaze.”
