As to _mentagra_, we have already proved a little above that it was a consequence of the vice of the _cunnilingue_, and as according to Pliny’s report the latter claimed Egypt for its fatherland, obviously the climate of that country must have been in part responsible for its origination. Now affections of the genital organs being found in Antiquity as the result of sexual intercourse, it follows that in this direction also Climate must have exerted its influence, and that in the very same way as we have just above seen it do,—in other words manifold affections of the skin must have originated in consequence of irritation and other morbid effects on the genital organs. True the Ancient physicians say not a word of this; but then they derive the greater proportion of the skin-diseases, which they mass all together in the most admired confusion, from internal mischief of various sorts, and regard them all as _apostases_ (suppurative inflammations carrying off the effect of fevers, etc.),—at any rate a proof they were not entirely unacquainted with the antagonistic relations existing between the skin and other organs. So far as the genitals are concerned, they seem to have adequately realized only the _consensus_ between the uterus and the skin[177], whereas in male subjects they appear to have put down most of the effects observed to the liver. But on these points we shall have something further to say later on. Still the assertion to the effect that Eunuchs are not attacked by _calvities_ (baldness) (_Hippocrates_, I. 400; _Galen_, XVIII. A. 40., also p. 42., where mention is made of the excesses _in Baccho et Venere_—in Wine and Love—peculiarly prevalent at his epoch), which was a frequent consequence of vice in Antiquity[178], points to the _consensus_ between genitals and skin having been already noted. Even more is the fact, vouched for by _Archigenes_[179], that castration was recommended by some Physicians as a cure for elephantiasis, such as to arouse the suspicion that the physicians of Antiquity knew perfectly well what influence affections of the genital organs exerted on diseases of the skin. This is made all the more likely by Archigenes (ch. 120.) not only speaking of the disease as being contagious, but also describing the skin-affection as secondary in character. He further declares its cause to be unknown, puts on record the extreme lubricity of the patients (Satyriasis pp. 74, 133, 269.), and even says in so many words that such as were castrated did not contract elephantiasis!
