As to the variety and weakness of the rationale of this art, they are more manifest in it than in any other art; aperitive medicines are proper for a man subject to the stone, by reason that opening and dilating the passages they help forward the slimy matter whereof gravel and stone are engendered, and convey that downward which begins to harden and gather in the reins; aperitive things are dangerous for a man subject to the stone, by reason that, opening and dilating the passages, they help forward the matter proper to create the gravel toward the reins, which by their own propension being apt to seize it, 'tis not to be imagined but that a great deal of what has been conveyed thither must remain behind; moreover, if the medicine happen to meet with anything too large to be carried through all the narrow passages it must pass to be expelled, that obstruction, whatever it is, being stirred by these aperitive things and thrown into those narrow passages, coming to stop them, will occasion a certain and most painful death. They have the like uniformity in the counsels they give us for the regimen of life: it is good to make water often; for we experimentally see that, in letting it lie long in the bladder, we give it time to settle the sediment, which will concrete into a stone; it is good not to make water often, for the heavy excrements it carries along with it will not be voided without violence, as we see by experience that a torrent that runs with force washes the ground it rolls over much cleaner than the course of a slow and tardy stream; so, it is good to have often to do with women, for that opens the passages and helps to evacuate gravel; it is also very ill to have often to do with women, because it heats, tires, and weakens the reins. It is good to bathe frequently in hot water, forasmuch as that relaxes and mollifies the places where the gravel and stone lie; it is also ill by reason that this application of external heat helps the reins to bake, harden, and petrify the matter so disposed. For those who are taking baths it is most healthful. To eat little at night, to the end that the waters they are to drink the next morning may have a better operation upon an empty stomach; on the other hand, it is better to eat little at dinner, that it hinder not the operation of the waters, while it is not yet perfect, and not to oppress the stomach so soon after the other labour, but leave the office of digestion to the night, which will much better perform it than the day, when the body and soul are in perpetual moving and action. Thus do they juggle and trifle in all their discourses at our expense; and they could not give me one proposition against which I should not know how to raise a contrary of equal force. Let them, then, no longer exclaim against those who in this trouble of sickness suffer themselves to be gently guided by their own appetite and the advice of nature, and commit themselves to the common fortune.
I have seen in my travels almost all the famous baths of Christendom, and for some years past have begun to make use of them myself: for I look upon bathing as generally wholesome, and believe that we suffer no little inconveniences in our health by having left off the custom that was generally observed, in former times, almost by all nations, and is yet in many, of bathing every day; and I cannot imagine but that we are much the worse by, having our limbs crusted and our pores stopped with dirt. And as to the drinking of them, fortune has in the first place rendered them not at all unacceptable to my taste; and secondly, they are natural and simple, which at least carry no danger with them, though they may do us no good, of which the infinite crowd of people of all sorts and complexions who repair thither I take to be a sufficient warranty; and although I have not there observed any extraordinary and miraculous effects, but that on the contrary, having more narrowly than ordinary inquired into it, I have found all the reports of such operations that have been spread abroad in those places ill-grounded and false, and those that believe them (as people are willing to be gulled in what they desire) deceived in them, yet I have seldom known any who have been made worse by those waters, and a man cannot honestly deny but that they beget a better appetite, help digestion, and do in some sort revive us, if we do not go too late and in too weak a condition, which I would dissuade every one from doing. They have not the virtue to raise men from desperate and inveterate diseases, but they may help some light indisposition, or prevent some threatening alteration. He who does not bring along with him so much cheerfulness as to enjoy the pleasure of the company he will there meet, and of the walks and exercises to which the amenity of those places invite us, will doubtless lose the best and surest part of their effect. For this reason I have hitherto chosen to go to those of the most pleasant situation, where there was the best conveniency of lodging, provision, and company, as the baths of Bagneres in France, those of Plombieres on the frontiers of Germany and Lorraine, those of Baden in Switzerland, those of Lucca in Tuscany, and especially those of Della Villa, which I have the most and at various seasons frequented.
Every nation has particular opinions touching their use, and particular rules and methods in using them; and all of them, according to what I have seen, almost with like effect. Drinking them is not at all received in Germany; the Germans bathe for all diseases, and will lie dabbling in the water almost from sun to sun; in Italy, where they drink nine days, they bathe at least thirty, and commonly drink the water mixed with some other drugs to make it work the better. Here we are ordered to walk to digest it; there we are kept in bed after taking it till it be wrought off, our stomachs and feet having continually hot cloths applied to them all the while; and as the Germans have a particular practice generally to use cupping and scarification in the bath, so the Italians have their 'doccie', which are certain little streams of this hot water brought through pipes, and with these bathe an hour in the morning, and as much in the afternoon, for a month together, either the head, stomach, or any other part where the evil lies. There are infinite other varieties of customs in every country, or rather there is no manner of resemblance to one another. By this you may see that this little part of physic to which I have only submitted, though the least depending upon art of all others, has yet a great share of the confusion and uncertainty everywhere else manifest in the profession.
The poets put what they would say with greater emphasis and grace; witness these two epigrams:
"Alcon hesterno signum Jovis attigit: ille,
Quamvis marmoreus, vim patitur medici.
Ecce hodie, jussus transferri ex aeede vetusta,
Effertur, quamvis sit Deus atque lapis."
["Alcon yesterday touched Jove's statue; he, although marble,
suffers the force of the physician: to-day ordered to be transferred
from the old temple, where it stood, it is carried out, although it
be a god and a stone."—Ausonius, Ep., 74.]
and the other:
"Lotus nobiscum est, hilaris coenavit; et idem
Inventus mane est mortuus Andragoras.
Tam subitae mortis causam, Faustine, requiris?
In somnis medicum viderat Hermocratem:"
