FERRARA
What we have to say of Ferrara has no relation to literature, but it has a very great one to justice, which is much more necessary than the belles-lettres, and much less cultivated, at least in Italy.
Ferrara was constantly a fief of the empire, like Parma and Placentia. Pope Clement VIII. robbed Cæsar d'Este of it by force of arms, in 1597. The pretext for this tyranny was a very singular one for a man who called himself the humble vicar of Jesus Christ.
Alphonso d'Este, the first of the name, sovereign of Ferrara, Modena, Este, Carpio, and Rovigno, espoused a simple gentlewoman of Ferrara, named Laura Eustochia, by whom he had three children before marriage. These children he solemnly acknowledged in the face of the Church. None of the formalities prescribed by the laws were wanting at this recognition. His successor, Alphonso d'Este, was acknowledged duke of Ferrara; he espoused Julia d'Urbino, the daughter of Francis, duke d'Urbino, by whom he had the unfortunate Cæsar d'Este, the incontestable heir of all the property of all the family, and declared so by the last duke, who died October 27, 1597. Pope Clement VIII., surnamed Aldobrandino, and originally of the family of a merchant of Florence, dared to pretend that the grandmother of Cæsar d'Este was not sufficiently noble, and that the children that she had brought into the world ought to be considered bastards. The first reason is ridiculous and scandalous in a bishop, the second is unwarrantable in every tribunal in Europe. If the duke was not legitimate, he ought to have lost Modena and his other states also; and if there was no flaw in his title, he ought to have kept Ferrara as well as Modena.
The acquisition of Ferrara was too fine a thing for the pope not to procure all the decretals and decisions of those brave theologians, who declare that the pope can render just that which is unjust. Consequently he first excommunicated Cæsar d'Este, and as excommunication necessarily deprives a man of all his property, the common father of the faithful raised his troops against the excommunicated, to rob him of his inheritance in the name of the Church. These troops were defeated, but the duke of Modena soon saw his finances exhausted, and his friends become cool.
To make his case still more deplorable, the king of France, Henry IV., believed himself obliged to take the side of the pope, in order to balance the credit of Philip II. at the court of Rome; in the same manner that good King Louis XII. less excusably dishonored himself by uniting with that monster Alexander VI., and his execrable bastard, the duke of Borgia. The duke was obliged to return, and the pope caused Ferrara to be invaded by Cardinal Aldobrandino, who entered this flourishing city at the head of a thousand horse and five thousand foot soldiers.
It is a great pity that such a man as Henry IV. descended to this unworthiness which is called politic. The Catos, Metelluses, Scipios, and Fabriciuses would not thus have betrayed justice to please a priest – and such a priest!
From this time Ferrara became a desert; its uncultivated soil was covered with standing marshes. This province, under the house of Este, had been one of the finest in Italy; the people always regretted their ancient masters. It is true that the duke was indemnified; he was nominated to a bishopric and a benefice; he was even furnished with some measures of salt from the mines of Servia. But it is no less true that the house of Modena has incontestable and imprescriptable rights to the duchy of Ferrara, of which it was thus shamefully despoiled.
Now, my dear reader, let us suppose that this scene took place at the time in which Jesus Christ appeared to his apostles after his resurrection, and that Simon Barjonas, surnamed Peter, wished to possess himself of the states of this poor duke of Ferrara. Imagine the duke coming to Bethany to demand justice of the Lord Jesus. Our Lord sends immediately for Peter and says to him, "Simon, son of Jonas, I have given thee the keys of heaven, but I have not given thee those of the earth. Because thou hast been told that the heavens surround the globe, and that the contained is in the containing, dost thou imagine that kingdoms here below belong to thee, and that thou hast only to possess thyself of whatever thou likest? I have already forbidden thee to draw the sword. Thou appearest to me a very strange compound; at one time cutting off the ear of Malchus, and at another even denying me. Be more lenient and decorous, and take neither the property nor the ears of any one for fear of thine own."
FEVER
It is not as a physician, but as a patient, that I wish to say a word or two on fever. We cannot help now and then speaking of our enemies; and this one has been attacking me for more than twenty years; not Fréron himself has been more implacable.
I ask pardon of Sydenham, who defined fever to be "an effort of nature, laboring with all its power to expel the peccant matter." We might thus define smallpox, measles, diarrhœa, vomitings, cutaneous eruptions, and twenty other diseases. But, if this physician defined ill, he practised well. He cured, because he had experience, and he knew how to wait.
Boerhaave says, in his "Aphorisms": "A more frequent opposition, and an increased resistance about the capillary vessels, give an absolute idea of an acute fever." These are the words of a great master; but he sets out with acknowledging that the nature of fever is profoundly hidden.
He does not tell us what that secret principle is which develops itself at regular periods in intermittent fever – what that internal poison is, which, after the lapse of a day, is renewed – where that flame is, which dies and revives at stated moments.
We know fairly well that we are liable to fever after excess, or in unseasonable weather. We know that quinine, judiciously administered, will cure it. This is quite enough; the how we do not know.
Every animal that does not perish suddenly dies by fever. The fever seems to be the inevitable effect of the fluids that compose the blood, or that which is in the place of blood. The structure of every animal proves to natural philosophers that it must, at all times, have enjoyed a very short life.
Theologians have held, as have promulgated other opinions. It is not for us to examine this question. The philosophers and physicians have been right in sensu humano, and the theologians, in sensu divino. It is said in Deuteronomy, xxviii, 22, that if the Jews do not serve the law they shall be smitten "with a consumption, and with a fever, and with an inflammation, and with an extreme burning." It is only in Deuteronomy, and in Molière's "Physician in Spite of Himself," that people have been threatened with fever.
It seems impossible that fever should not be an accident natural to an animate body, in which so many fluids circulate; just as it is impossible for an animate body not to be crushed by the falling of a rock.
Blood makes life; it furnishes the viscera, the limbs, the skin, the very extremities of the hairs and nails with the fluids, the humors proper for them.
This blood, by which the animal has life, is formed by the chyle. During pregnancy this chyle is transmitted from the uterus to the child, and, after the child is born, the milk of the nurse produces this same chyle. The greater diversity of aliments it afterwards receives, the more the chyle is liable to be soured. This alone forming the blood, and this blood, composed of so many different humors so subject to corruption, circulating through the whole human body more than five hundred and fifty times in twenty-four hours, with the rapidity of a torrent, it is not only astonishing that fever is not more frequent, it is astonishing that man lives. In every articulation, in every gland, in every passage, there is danger of death; but there are also as many succors as there are dangers. Almost every membrane extends or contracts as occasion requires. All the veins have sluices which open and shut, giving passage to the blood and preventing a return, by which the machine would be destroyed. The blood, rushing through all these canals, purifies itself. It is a river that carries with it a thousand impurities; it discharges itself by perspiration, by transpiration, by all the secretions. Fever is itself a succor; it is a rectification when it does not kill.
Man, by his reason, accelerates the cure by administering bitters, and, above all, by regimen. This reason is an oar with which he may row for some time on the sea of the world when disease does not swallow him up.
It is asked: How is it that nature has abandoned the animals, her work, to so many horrible diseases, almost always accompanied by fever? How and why is it that so many disorders exist with so much order, formation, and destruction everywhere, side by side? This is a difficulty that often gives me a fever, but I beg you will read the letters of Memmius. Then, perhaps, you will be inclined to suspect that the incomprehensible artificer of vegetables, animals, and worlds, having made all for the best, could not have made anything better.
FICTION
Is not a fiction, which teaches new and interesting truths, a fine thing? Do you not admire the Arabian story of the sultan who would not believe that a little time could appear long, and who disputed with his dervish on the nature of duration? The latter to convince him of it, begged him only to plunge his head for a moment into the basin in which he was washing. Immediately the sultan finds himself transported into a frightful desert; he is obliged to labor to get a livelihood; he marries, and has children who grow up and ill treat him; finally he returns to his country and his palace and he there finds the dervish who has caused him to suffer so many evils for five and twenty years. He is about to kill him, and is only appeased when he is assured that all passed in the moment in which, with his eyes shut, he put his head into the water.
You still more admire the fiction of the loves of Dido and Æneas, which caused the mortal hatred between Carthage and Rome, as also that which exhibits in Elysium the destinies of the great men of the Roman Empire.
You also like that of Alcina, in Ariosto, who possesses the dignity of Minerva with the beauty of Venus, who is so charming to the eyes of her lovers, who intoxicates them with voluptuous delights, and unites all the loves and graces, but who, when she is at last reduced to her true self and the enchantment has passed away, is nothing more than a little shrivelled, disgusting, old woman.
As to fictions which represent nothing, teach nothing, and from which nothing results, are they anything more than falsities? And if they are incoherent and heaped together without choice, are they anything better than dreams?
You will possibly tell me that there are ancient fictions which are very incoherent, without ingenuity, and even absurd, which are still admired; but is it not rather owing to the fine images which are scattered over these fictions than to the inventions which introduce them? I will not dispute the point, but if you would be hissed at by all Europe, and afterwards forgotten forever, write fictions similar to those which you admire.
FIERTÉ
Fierté is one of those expressions, which, having been originally employed in an offensive sense, are afterwards used in a favorable one. It is censure when this word signifies high-flown, proud, haughty, and disdainful. It is almost praise when it means the loftiness of a noble mind.
It is a just eulogium on a general who marches towards the enemy with fierté. Writers have praised the fierté of the gait of Louis XIV.; they should have contented themselves with remarking its nobleness.
Fierté, without dignity, is a merit incompatible with modesty. It is only fierté in air and manners which offends; it then displeases, even in kings.
Fierté of manner in society is the expression of pride; fierté of soul is greatness. The distinctions are so nice that a proud spirit is deemed blamable, while a proud soul is a theme of praise. By the former is understood one who thinks advantageously of himself while the latter denotes one who entertains elevated sentiments.
Fierté, announced by the exterior, is so great a fault that the weak, who abjectly praise it in the great are obliged to soften it, or rather to extol it, by speaking of "this noble fierté." It is not simply vanity, which consists in setting a value upon little things; it is not presumption, which believes itself capable of great ones; it is not disdain, which adds contempt of others to a great opinion of self; but it is intimately allied to all these faults.
This word is used in romances, poetry, and above all, in operas, to express the severity of female modesty. We meet with vain fierté, vigorous fierté, etc. Poets are, perhaps, more in the right than they imagine. The fierté of a woman is not only rigid modesty and love of duty, but the high value which she sets upon her beauty. The fierté of the pencil is sometimes spoken of to signify free and fearless touches.
FIGURE
Every one desirous of instruction should read with attention all the articles in the "Dictionnaire Encyclopédique," under the head "Figure," viz.:
"Figure of the Earth," by M. d'Alembert – a work both clear and profound, in which we find all that can be known on the subject.
"Figure of Rhetoric," by César Dumarsais – a piece of instruction which teaches at once to think and to write; and, like many other articles, make us regret that young people in general have not a convenient opportunity of reading things so useful.
"Human Figure," as relating to painting and sculpture – an excellent lesson given to every artist, by M. Watelet.
"Figure," in physiology – a very ingenious article, by M. de Caberoles.
"Figure," in arithmetic and in algebra – by M. Mallet.
"Figure," in logic, in metaphysics, and in polite literature, by M. le Chevalier de Jaucourt – a man superior to the philosophers of antiquity, inasmuch as he has preferred retirement, real philosophy, and indefatigable labor, to all the advantages that his birth might have procured him, in a country where birth is set above all beside, excepting money.
Figure or Form of the Earth.
Plato, Aristotle, Eratosthenes, Posidonius, and all the geometricians of Asia, of Egypt, and of Greece, having acknowledged the sphericity of our globe, how did it happen that we, for so long a time, imagined that the earth was a third longer than it was broad, and thence derived the terms "longitude" and "latitude," which continually bear testimony to our ancient ignorance?
The reverence due to the "Bible," which teaches us so many truths more necessary and more sublime, was the cause of this, our almost universal error. It had been found, in Psalm ciii, that God had stretched the heavens over the earth like a skin; and as a skin is commonly longer than it is wide, the same was concluded of the earth.
St. Athanasius expresses himself as warmly against good astronomers as against the partisans of Arius and Eusebius. "Let us," says he, "stop the mouths of those barbarians, who, speaking without proof, dare to assert that the heavens also extend under the earth." The fathers considered the earth as a great ship, surrounded by water, with the prow to the east, and the stern to the west. We still find, in "Cosmos," a work of the fourth century, a sort of geographical chart, in which the earth has this figure.
Tortato, bishop of Avila, near the close of the fifteenth century, declares in his commentary on Genesis, that the Christian faith is shaken, if the earth is believed to be round. Columbus, Vespucius, and Magellan, not having the fear of excommunication by this learned bishop before their eyes, the earth resumed its rotundity in spite of him.
Then man went from one extreme to the other, and the earth was regarded as a perfect sphere. But the error of the perfect sphere was the mistake of philosophers, while that of a long, flat earth was the blunder of idiots.
When once it began to be clearly known that our globe revolves on its own axis every twenty-four hours, it might have been inferred from that alone that its form could not be absolutely round. Not only does the centrifugal zone considerably raise the waters in the region of the equator, by the motion of the diurnal rotation, but they are moreover elevated about twenty-five feet, twice a day, by the tides; the lands about the equator must then be perfectly inundated. But they are not so; therefore the region of the equator is much more elevated, in proportion, than the rest of the earth: then the earth is a spheroid elevated at the equator, and cannot be a perfect sphere. This proof, simple as it is, had escaped the greatest geniuses: because a universal prejudice rarely permits investigation.
We know that, in 1762, in a voyage to Cayenne, near the line, undertaken by order of Louis XIV., under the auspices of Colbert, the patron of all the arts, Richer, among many other observations, found that the oscillations or vibrations of his timepiece did not continue so frequent as in the latitude of Paris, and that it was absolutely necessary to shorten the pendulum one line and something more than a quarter. Physics and geometry were at that time not nearly so much cultivated as they now are; what man would have believed that an observation so trivial in appearance, a line more or less, could lead to the knowledge of the greatest physical truths? It was first of all discovered that the weight must necessarily be less on the equator than in our latitudes, since weight alone causes the oscillation of a pendulum. Consequently, the weight of bodies being the less the farther they are from the centre of the earth, it was inferred that the region of the equator must be much more elevated than our own – much more remote from the centre; so the earth could not be an exact sphere.
Many philosophers acted, on the occasion of these discoveries, as all men act when an opinion is to be changed – they disputed on Richer's experiment; they pretended that our pendulums made their vibrations more slowly about the equator only because the metal was lengthened by the heat; but it was seen that the heat of the most burning summer lengthens it but one line in thirty feet; and here was an elongation of a line and a quarter, a line and a half, or even two lines, in an iron rod, only three feet and eight lines long.
Some years after MM. Varin, Deshayes, Feuillée, and Couplet, repeated the same experiment on the pendulum, near the equator; and it was always found necessary to shorten it, although the heat was very often less on the line than fifteen or twenty degrees from it. This experiment was again confirmed by the academicians whom Louis XV. sent to Peru; and who were obliged, on the mountains about Quito, where it froze, to shorten the second pendulum about two lines.
About the same time, the academicians who went to measure an arc of the meridian in the north, found that at Pello, within the Polar circle, it was necessary to lengthen the pendulum, in order to have the same oscillations as at Paris: consequently weight is greater at the polar circle than in the latitude of France, as it is greater in our latitude than at the equator. Weight being greater in the north, the north was therefore nearer the centre of the earth than the equator; therefore the earth was flattened at the poles.
Never did reasoning and experiment so fully concur to establish a truth. The celebrated Huygens, by calculating centrifugal forces, had proved that the consequent diminution of weight on the surface of a sphere was not great enough to explain the phenomena, and that therefore the earth must be a spheroid flattened at the poles. Newton, by the principles of attraction, had found nearly the same relations: only it must be observed, that Huygens believed this force inherent in bodies determining them towards the centre of the globe, to be everywhere the same. He had not yet seen the discoveries of Newton; so that he considered the diminution of weight by the theory of centrifugal forces only. The effect of centrifugal forces diminishes the primitive gravity on the equator. The smaller the circles in which this centrifugal force is exercised become, the more it yields to the force of gravity; thus, at the pole itself the centrifugal force being null, must leave the primitive gravity in full action. But this principle of a gravity always equal, falls to nothing before the discovery made by Newton, that a body transported, for instance, to the distance of ten diameters from the centre of the earth, would weigh one hundred times less than at the distance of one diameter.
It is then by the laws of gravitation, combined with those of the centrifugal force, that the real form of the earth must be shown. Newton and Gregory had such confidence in this theory that they did not hesitate to advance that experiments on weight were a surer means of knowing the form of the earth than any geographical measurement.
Louis XIV. had signalized his reign by that meridian which was drawn through France: the illustrious Dominico Cassini had begun it with his son; and had, in 1701, drawn from the feet of the Pyrenees to the observatory a line as straight as it could be drawn, considering the almost insurmountable obstacles which the height of mountains, the changes of refraction in the air, and the altering of instruments were constantly opposing to the execution of so vast and delicate an undertaking; he had, in 1701, measured six degrees eighteen minutes of that meridian. But, from whatever cause the error might proceed, he had found the degrees towards Paris, that is towards the north, shorter than those towards the Pyrenees and the south. This measurement gave the lie both to the theory of Norwood and to the new theory of the earth flattened at the poles. Yet this new theory was beginning to be so generally received that the academy's secretary did not hesitate, in his history of 1701, to say that the new measurements made in France proved the earth to be a spheroid flattened at the poles. The truth was, that Dominico Cassini's measurement led to a conclusion directly opposite; but, as the figure of the earth had not yet become a question in France, no one at that time was at the trouble of combating this false conclusion. The degrees of the meridian from Collioure to Paris were believed to be exactly measured; and the pole, which from that measurement must necessarily be elongated, was believed to be flattened.
An engineer, named M. de Roubais, astonished at this conclusion, demonstrated that, by the measurements taken in France, the earth must be an oblate spheroid, of which the meridian passing through the poles must be longer than the equator, the poles being elongated. But of all the natural philosophers to whom he addressed his dissertation, not one would have it printed; because it seemed that the academy had pronounced it as too bold in an individual to raise his voice. Some time after the error of 1701 was acknowledged, that which had been said was unsaid; and the earth was lengthened by a just conclusion drawn from a false principle. The meridian was continued in the same principle from Paris to Dunkirk; and the degrees were still found to grow shorter as they approached the north. People were still mistaken respecting the figure of the earth, as they had been concerning the nature of light. About the same time, some mathematicians who were performing the same operations in China were astonished to find a difference among their degrees, which they had expected to find alike; and to discover, after many verifications, that they were shorter towards the north than towards the south. This accordance of the mathematicians of France with those of China was another powerful reason for believing in the oblate spheroid. In France they did still more; they measured parallels to the equator. It is easily understood that on an oblate spheroid our degrees of longitude must be shorter than on a sphere. M. de Cassini found the parallel which passes through St. Malo to be shorter by one thousand and thirty-seven toises than it would have been on a spherical earth.
All these measurements proved that the degrees had been found as it was wished to find them. They overturned, for a time, in France, the demonstrations of Newton and Huygens; and it was no longer doubted that the poles were of a form precisely contrary to that which had at first been attributed to them. In short, nothing at all was known about the matter.
At length, other academicians, who had visited the polar circle in 1736, having found, by new measurements, that the degree was longer there than in France, people doubted between them and the Cassinis. But these doubts were soon after removed: for these same astronomers, returning from the pole, examined afresh the degree to the north of Paris, measured by Picard, in 1677, and found it to be a hundred and twenty-three toises longer than it was according to Picard's measurement. If, then, Picard, with all his precautions, had made his degree one hundred and twenty-three toises too short, it was not at all unlikely that the degrees towards the south had in like manner been found too long. Thus the first error of Picard, having furnished the foundations for the measurements of the meridian, also furnished an excuse for the almost inevitable errors which very good astronomers might have committed in the course of these operations.
Unfortunately, other men of science found that, at the Cape of Good Hope, the degrees of the meridian did not agree with ours. Other measurements, taken in Italy, likewise contradicted those of France, and all were falsified by those of China. People again began to doubt, and to suspect, in my opinion quite reasonably, that the earth had protuberances. As for the English, though they are fond of travelling, they spared themselves the fatigue, and held fast their theory.
The difference between one diameter and the other is not more than five or six of our leagues – a difference immense in the eyes of a disputant, but almost imperceptible to those who consider the measurement of the globe only in reference to the purposes of utility which it may serve. A geographer could scarcely make this difference perceptible on a map; nor would a pilot be able to discover whether he was steering on a spheroid or on a sphere. Yet there have been men bold enough to assert that the lives of navigators depended on this question. Oh quackery! will you spare no degrees – not even those of the meridian?
