It is greatly to be lamented that Cælius Aurelianus’ account of elephantiasis has come down to us in an imperfect state. His description is entirely lost, and his detail of the treatment is in a mutilated state. It appears, however, that his views were similar to those of Celsus, and that he considered it to be a malignant disease, affecting principally the skin. He approves of rubbing stimulant ointments into the skin, and of using medicinal baths, especially the aluminous and chalybeate. When the applications produce ulceration of the skin, he directs us to treat it upon general principles. He makes mention of vomiting by radishes, and latterly by means of the white hellebore. He approves of a sea voyage and change of scene. He says the first author who described elephantiasis was Themison, the same person that is damned to everlasting fame in one of the lines of Juvenal: “Quot Themison agros autumno occiderit uno.” (Sat. x, 221.) If this statement be correct, it is clear that Celsus cannot be of so early a date as is generally believed, that is to say, the Augustan age, for Themison flourished towards the end of the first century, P. C. He was the founder of the Methodical sect. Cælius also blames Themison for recommending bleeding and vomiting unseasonably, and disapproves of his directions respecting the applications to the skin. It appears that he also disapproved of the theriac of vipers, and of giving to drink water in which red-hot iron had been extinguished. There can be no doubt, from the circumstances which he mentions, that the disease was thought contagious in his time. Octavius Horatianus, who lived under the emperor Valentinian, gives a pretty full detail of the treatment, but his description of the symptoms is defective. He makes mention, however, of _maculæ_, which affect principally the face; he contends that the whole system is attacked with the disease, and that the flesh is corrupted. His remedies are much the same as those recommended by the other authorities, namely, bleeding, purging, vomiting, the theriac of vipers, and rubbing with the usual applications for scabies. He also speaks favorably of the natural and the sea-water baths. Marcellus the Emperic, who is supposed to have flourished in the reign of Theodosius, recommends, like Serenus, mint, juniper, and mezereon, for elephantiasis. He describes it as being attended with hard excrescences of the extremities, eruptions on the face, and disease of the bones. He speaks of its being endemic in Ægypt. The disease, elephantiasis, according to Isidorus, is so called from its resemblance to the elephant. The skin in it is hard and rough, from which it gets its appellation, because the surface of the patient’s body resembles that of an elephant; or because it is a mighty affection, as the elephant is one of the largest of animals.
