I. THIS Disease is called in Greek, 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, à 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, Serpo; in Latin, Her∣pes simplex, Formica; in English, the Shingles.
II. The Description. Shingles, are little Cholerick-pustles, pure, and unmixt with other Humors; creeping upon the surface or skin of some part of the Body, from place to place, broad, and after a circular manner; the middle parts healing, while it breaks out farther afresh.
III. The Differences. A Her∣pes is threefold: 1. Simple, of which we treat in this Chapter. 2. Miliaris, Ulcerous Pustles, breaking out like Millet-seed. 3. Exedens, the Eating-herpes; which eats thro', and devours the Skin, and sometimes the Flesh too: but of these two latter, we shall treat in the third Book following.
IV. The simple Herpes differs from Phlyctaenae, or blister-like Eruptions; because they are gene∣rally Critical, and happen mostly in the Face, about the Cheeks, Lips, or Chin; and foreshew the mending of the Patient; and may very properly be called Critical-Shingles, or Shingles of the Lips: whereas what we speak of in this Chapter, are rather Symptomatical than Cri∣tical, and always happen in other parts of the Body.
V. It differs also from Psydra∣cia; which tho' they be bladder-like Pustles, yet they always happen in the Head: and by some are taken for one of the kinds of Scalds.
VI. The Signs. It seems to creep like unto a Snake; and no sooner does one part seem to be healed and well, but presently the Disease creeps unto the next adjacent parts.
VII. The Causes. Authors will have it to arise from sincere and pure Choler, severed and sepa∣rated from the rest of the Humors; which by its thinness pierces even to the Scarf-skin, and is diffused thro' it; making this appearance in a small tu∣mor, but less than in an Ery∣sipelas.
VIII. Now this simple Herpes is manifest to the Senses; for it is a broad tumor, which has little or no height in it: so that the Part is scarcely lifted up at all, but may rather seem to be exasperated, than to swell up to any height.
IX. There is also accompanying it a certain kind of hardness and pain; and as it were a certain sense or feeling of Heat or Burning; purely occasioned from the Cholerick Humor.
X. The Prognosticks. The Disease is accounted more or less troublesom, difficult to be cured,
