"With respect to the sweating-houses, as they are called, I remember about forty years ago seeing one in the island of Rathlin, and shall try to give you a description of it. It was built of basalt stones, very much in the shape of a bee-hive, with a row of stones inside, for the person to sit on when undergoing the operation. There was a hole at the top, and one near the ground, where the person crept in and seated him or herself, the stones having been heated in the same way as an oven for baking bread is, the hole on the top being covered with a sod while being heated, but I suppose removed to admit the person to breathe. Before entering, the patient was stripped quite naked, and on coming out, dressed again in the open air. The process was reckoned a sovereign cure for rheumatism and all sorts of pains and aches."
Dr. Haughton on the same subject remarks that:—"Two varieties of Tig Allui, or sweating-houses, exist in Ireland, one kind being capable of containing a good many persons, and the other only intended for a single occupant." The former is that just described: it is heated in the same way as an oven, by making a large fire of wood in the middle of the floor, and after the wood is burnt out, sweeping away the ashes. Besides the cure of rheumatism, the young girls who have tarnished their complexion in the process of burning kelp or sea-weed for the manufacture of soda, also resort to the Tig Allui for the purpose of clearing their skin. The usual time for remaining in the bath is under the half hour.
The second kind of Tig Allui—namely, that for the reception of a single person only—is described by Dr. Tucker, of Sligo, as follows:—
"It is built of stone and mortar, and brought to a round top. It is sufficiently large for one person to sit on a chair inside, the door being merely large enough to admit a person on his hands and knees. When any of the old people of the neighbourhood, men or women, are seized with pains, they at once have recourse to the sweat-house, which is brought to the proper temperature by placing therein a large turf fire, after the manner of an oven, which is left until it is burned quite down, the door being a flat stone and air-tight, and the roof, or outside of the house, being covered with clay, to the depth of about a foot, to prevent the least escape of heat. When the remains of the fire are taken out, the floor is strewn with green rushes, and the person to be cured is escorted to the bath by a second person carrying a pair of blankets. The invalid, having crept in, plants himself or herself in a chair, and there remains until the perspiration rolls off in large drops. When sufficiently operated on, he or she, as the case may be, is anxious to get out, and the person in waiting swaddles him up in the blankets, and off home, and then to bed. I have heard old people say that they would not have been alive, twenty years ago, only for the sweating-house.... Remains of the Tig Allui are also found in the county Tyrone, of the following dimensions:—five feet in height, nine in length, and four in width, being built of solid masonry, and shaped like a bee-hive at the top."
Another, and a very important step in the progress of the bath was the contrivance of a mode of heating by means of which the temperature might be made uniform, and might be regulated in any manner that should be required. The hot stones of the North American medicine-man were clearly a very bungling and uncertain expedient; little better than the warm skin of a newly-killed animal; and the wood fire of the Irish sweating-houses was more objectionable still, not only on account of the impossibility of regulating the heat, but also from the resulting impurity of the atmosphere and the danger of leaving fragments of the heated ashes on the floor. The next contrivance, and that which has continued to be the practice up to the present day, was the construction of a furnace under the floor—in other words, a hypocaust. Mr. Urquhart, speaking of the existence of baths among the Mexicans and their probable introduction by the Phœnicians, remarks:—"However magnificent their public monuments," their baths were "such as are found in almost every house in Morocco,—a small apartment seven feet square, with a cupola roof five to six feet high, and a slightly convex floor, under one side of which there is a fire, and a small low door to creep in by."
Reviewing the probable rise and progress of the bath, there seems little doubt that the bath took its origin in the East, the dwelling-place of our first parents, the birth-place of civilization and knowledge. It was known at a very early period in Phœnicia. Mr. Urquhart, in his recent work, "The Lebanon,"[4] relates his discovery of a Phœnician temple, or crypt, among the ruins of Baalbeck, or Baalbeth, the House of Baal—the Heliopolis, or City of the Sun, of the Greeks; in which were traces of the existence of the bath. "But the Phœnician crypt was not my only discovery. In a gap opening a few feet into the masonry, I found mortar hard as stone where exposed to the air, but soft within. Yet it was unlike other mortar; it was dark grey, with particles of charcoal; when I brought out some, it was recognised at once, and called kissermil, or ashes from the bath. Those ashes are still used in this country for mortar, which with this addition becomes as hard as stone. According to the old construction, the baths were heated as an oven is, brushwood and dung being used as well as wood. The combustion not being complete, there remain various chemical compounds, alkali, ammonia, sulphate and carbonate of lime, and carbon, which by entering into new combinations, bind the mortar into a distinct substance."
"One thing is clear, there were baths at Baalbeck. In the elaborately finished bath of Emir Beshir at Ibtedeen, one peculiarity struck me as evidencing their high antiquity in this land. It was the absence of cocks; instead of which simple plugs or clots of cloth were used for the pipes which brought the water into the basins. As the Romans and Greeks used cocks, the art of the bath had not been derived from them, but traced beyond them. Still it was curious to observe these ashes in the midst of Cyclopic blocks. And yet why should not the bath have belonged to the very earliest period of human society? It is sufficiently excellent to be from the beginning."
"I remembered that in opening up the pavement of an ancient bath on the western coast of Africa, I had come upon a somewhat similar deposit, in large quantities, under the floor. This was gazul, the product of a certain mountain in Morocco, resembling soapstone, but composed of an admixture of silex, alumina, magnesia, and lime, and which has the peculiar property of polishing the skin when rubbed upon it, and so cleaning off the dead epidermis. Being used for this purpose largely in the baths, the grey deposit under the ruin in question is easily accounted for. Might not this same gazul, mixed with kissermil, have been the deposit which I took for mortar at Baalbeck?"
