Famam Dipsas habet terris adjuta perastis.”
Pharsal. ix, 754.
[1] Sic lege non factiq.
The Arabians give a similar description of its effects. Haly Abbas says, that it occasions great heat and burning. Dioscorides treats the wounds of the dipsas and hæmorrhus upon general principles, namely, by the external application of cauteries and cataplasms; and the internal administration of wine and acrid food. Actuarius, in like manner, recommends undiluted wine and acrid food, and also directs us to amputate the part, or apply acrid cataplasms according to the degree of danger. Most of the ancient authorities concur in recommending the theriac; for an account of the modus operandi of which in this case, see Alexander Aphrodisiensis (Prob. i, 152.)
We may mention that, after considering the descriptions given by Nicander, his commentator Eutecnius, Galen, Actuarius, and Avicenna, we are disposed to think that the text of our author at the beginning of this section must be corrupt; but we have not ventured to deviate from it, as we could not hit upon a conjectural emendation to satisfy us. None of the others mention contractions of the interstices or porous parts of the body, and all state that there is a discharge of blood from the pores of the skin. Now it is not probable that our author should have omitted a symptom so striking as this cutaneous hemorrhage, and substituted one which the others take no notice of.
Sprengel makes the dipsas to be the coluber prester, and the hæmorrhus the C. cerastes. That they were both vipers is quite obvious from the ancient descriptions of them, and more especially from the account of them given by Galen. (l. c.)
SECT. XVI.—ON THE HYDRUS, OR WATER SERPENT.
When a person has been bitten by a water serpent, the wound becomes broad, large, and pale, and a black, copious, and fetid discharge, as from a spreading ulcer, takes place, and the cure of the mischief is accomplished only after a length of time, and with difficulty. Wherefore powdered marjoram mixed with water is to be applied to their bites, or oak ashes mixed with oil, or barley-flour with melted honey is given to drink, and birthwort to the amount of two drachms in diluted wine, or two cyathi of oxycrate; and afterwards the juice of horehound, or its decoction with wine, or wild cresses, or the fruit of asphodel, or the flour or the seed of hog’s fennel, with wine. A fresh honeycomb may also be eaten with vinegar.
Commentary. This section is taken almost word for word from Dioscorides. The chersydros, says Nicander, is like the asp, and its bite is followed by malignant symptoms. The skin about the wound becomes parched and putrid, along with heat and pains all over the body. Isidorus says of it: “Hydros aquatilis serpens a quo icti obturgescunt.” (Orig. xii, 4.) See also Pliny. (H. N. xxix, 22.) Haly Abbas says, it occasions lividity of the part, from which a black fetid discharge takes place. (Theor. viii, 21.)
Bochart makes this to have been the serpent which so annoyed the children of Israel in the wilderness. (Hier. ii, 421.)
