CAUSES.—SPREAD.
An inquiry into the causes of the Black Death, will not be without
important results in the study of the plagues which have visited
the world, although it cannot advance beyond generalization without
entering upon a field hitherto uncultivated, and, to this hour,
entirely unknown. Mighty revolutions in the organism of the earth, of
which we have credible information, had preceded it. From China to the
Atlantic, the foundations of the earth were shaken,—throughout Asia and
Europe the atmosphere was in commotion, and endangered, by its baneful
influence, both vegetable and animal life.
The series of these great events began in the year 1333, fifteen years
before the plague broke out in Europe: they first appeared in China.
Here a parching drought, accompanied by famine, commenced in the tract
of country watered by the rivers Kiang and Hoai. This was followed
by such violent torrents of rain, in and about Kingsai, at that time
the capital of the empire, that, according to tradition, more than
400,000 people perished in the floods. Finally the mountain Tsincheou
fell in, and vast clefts were formed in the earth. In the succeeding
year (1334), passing over fabulous traditions, the neighbourhood of
Canton was visited by inundations; whilst in Tche, after an unexampled
drought, a plague arose, which is said to have carried off about
5,000,000 of people. A few months afterwards an earthquake followed,
at and near Kingsai; and subsequent to the falling in of the mountains
of Ki-ming-chan, a lake was formed of more than a hundred leagues in
circumference, where, again, thousands found their grave. In Hou-kouang
and Ho-nan, a drought prevailed for five months; and innumerable swarms
of locusts destroyed the vegetation; while famine and pestilence, as
usual, followed in their train. Connected accounts of the condition
of Europe before this great catastrophe, are not to be expected from
the writers of the fourteenth century. It is remarkable, however,
that simultaneously with a drought and renewed floods in China, in
1336, many uncommon atmospheric phenomena, and in the winter, frequent
thunder storms, were observed in the north of France; and so early
as the eventful year of 1333, an eruption of Etna took place[34].
According to the Chinese annals, about 4,000,000 of people perished by
famine in the neighbourhood of Kiang in 1337: and deluges, swarms of
locusts, and an earthquake which lasted six days, caused incredible
devastation. In the same year, the first swarms of locusts appeared in
Franconia, which were succeeded in the following year by myriads of
these insects. In 1338, Kingsai was visited by an earthquake of ten
days’ duration; at the same time France suffered from a failure in the
harvest; and thenceforth, till the year 1342, there was in China, a
constant succession of inundations, earthquakes, and famines. In the
same year great floods occurred in the vicinity of the Rhine and in
France, which could not be attributed to rain alone; for, everywhere,
even on the tops of mountains, springs were seen to burst forth, and
dry tracts were laid under water in an inexplicable manner. In the
following year, the mountain Hong-tchang, in China, fell in, and caused
a destructive deluge; and in Pien-tcheou and Leang-tcheou, after three
months’ rain, there followed unheard-of inundations, which destroyed
seven cities. In Egypt and Syria, violent earthquakes took place; and
in China they became, from this time, more and more frequent; for
they recurred, in 1344, in Ven-tcheou, where the sea overflowed in
consequence; in 1345, in Ki-tcheou, and in both the following years
in Canton, with subterraneous thunder. Meanwhile, floods and famine
devastated various districts, until 1347, when the fury of the elements
subsided in China[35].
The signs of terrestrial commotions commenced in Europe in the year
1348, after the intervening districts of country in Asia had probably
been visited in the same manner.
On the island of Cyprus, the plague from the East had already broken
out; when an earthquake shook the foundations of the island, and was
accompanied by so frightful a hurricane, that the inhabitants who had
slain their Mahometan slaves, in order that they might not themselves
be subjugated by them, fled in dismay, in all directions. The sea
overflowed—the ships were dashed to pieces on the rocks, and few
outlived the terrific event, whereby this fertile and blooming island
was converted into a desert. Before the earthquake, a pestiferous wind
spread so poisonous an odour, that many, being overpowered by it, fell
down suddenly and expired in dreadful agonies[36].
This phenomenon is one of the rarest that has ever been observed, for
nothing is more constant than the composition of the air; and in no
respect has nature been more careful in the preservation of organic
life. Never have naturalists discovered in the atmosphere foreign
elements, which, evident to the senses, and borne by the winds, spread
from land to land, carrying disease over whole portions of the earth,
as is recounted to have taken place in the year 1348. It is, therefore,
the more to be regretted, that in this extraordinary period, which,
owing to the low condition of science, was very deficient in accurate
observers, so little that can be depended on respecting those uncommon
occurrences in the air, should have been recorded. Yet, German accounts
say expressly, that a thick, stinking mist advanced from the East, and
spread itself over Italy[37]; and there could be no deception in so
palpable a phenomenon[38]. The credibility of unadorned traditions,
however little they may satisfy physical research, can scarcely be
called in question when we consider the connexion of events; for just
at this time earthquakes were more general than they had been within
the range of history. In thousands of places chasms were formed, from
whence arose noxious vapours; and as at that time natural occurrences
were transformed into miracles, it was reported, that a fiery meteor,
which descended on the earth far in the East, had destroyed every
thing within a circumference of more than a hundred leagues, infecting
the air far and wide[39]. The consequences of innumerable floods
contributed to the same effect; vast river districts had been converted
into swamps; foul vapours arose everywhere, increased by the odour of
putrified locusts, which had never perhaps darkened the sun in thicker
swarms[40], and of countless corpses, which, even in the well regulated
countries of Europe, they knew not how to remove quickly enough out of
the sight of the living. It is probable, therefore, that the atmosphere
contained foreign, and sensibly perceptible, admixtures to a great
extent, which, at least in the lower regions, could not be decomposed,
or rendered ineffective by separation.
Now, if we go back to the symptoms of the disease, the ardent
inflammation of the lungs points out, that the organs of respiration
yielded to the attack of an atmospheric poison—a poison, which, if we
admit the independent origin of the Black Plague at any one place on
the globe, which, under such extraordinary circumstances, it would
be difficult to doubt, attacked the course of the circulation in as
hostile a manner as that which produces inflammation of the spleen, and
other animal contagions that cause swelling and inflammation of the
lymphatic glands.
Pursuing the course of these grand revolutions further, we find notice
of an unexampled earthquake, which, on the 25th of January, 1348, shook
Greece, Italy, and the neighbouring countries. Naples, Rome, Pisa,
Bologna, Padua, Venice and many other cities suffered considerably:
whole villages were swallowed up. Castles, houses and churches were
overthrown, and hundreds of people were buried beneath their ruins[41].
In Carinthia, thirty villages, together with all the churches, were
demolished; more than a thousand corpses were drawn out of the rubbish;
the city of Villach was so completely destroyed, that very few of
its inhabitants were saved; and when the earth ceased to tremble, it
was found that mountains had been moved from their positions, and
that many hamlets were left in ruins[42]. It is recorded that, during
this earthquake, the wine in the casks became turbid, a statement
which may be considered as furnishing a proof, that changes causing a
decomposition of the atmosphere had taken place; but if we had no other
information from which the excitement of conflicting powers of nature
during these commotions might be inferred, yet scientific observations
in modern times have shewn, that the relation of the atmosphere to the
earth is changed by volcanic influences. Why then, may we not, from
this fact, draw retrospective inferences respecting those extraordinary
phenomena?
Independently of this, however, we know that during this earthquake,
the duration of which is stated by some to have been a week, and by
others a fortnight, people experienced an unusual stupor and headache,
and that many fainted away[43].
These destructive earthquakes extended as far as the neighbourhood
of Basle[44], and recurred until the year 1360, throughout Germany,
France, Silesia, Poland, England and Denmark, and much further
north[45].
Great and extraordinary meteors appeared in many places, and were
regarded with superstitious horror. A pillar of fire, which on the 20th
of December, 1348, remained for an hour at sunrise over the pope’s
palace in Avignon[46]; a fireball, which in August of the same year
was seen at sunset over Paris, and was distinguished from similar
phenomena, by its longer duration[47], not to mention other instances
mixed up with wonderful prophecies and omens, are recorded in the
chronicles of that age.
The order of the seasons seemed to be inverted,—rains, floods and
failures in crops were so general, that few places were exempt from
them; and though an historian of this century assures us, that there
was an abundance in the granaries and storehouses[48], all his
contemporaries, with one voice, contradict him. The consequences of
failure in the crops were soon felt, especially in Italy and the
surrounding countries, where, in this year, a rain which continued for
four months, had destroyed the seed. In the larger cities, they were
compelled, in the spring of 1347, to have recourse to a distribution
of bread among the poor, particularly at Florence, where they erected
large bake-houses, from which, in April, ninety-four thousand loaves of
bread, each of twelve ounces in weight, were daily dispensed[49]. It is
plain, however, that humanity could only partially mitigate the general
distress, not altogether obviate it.
Diseases, the invariable consequence of famine, broke out in the
country, as well as in cities; children died of hunger in their
mothers’ arms,—want, misery and despair, were general throughout
Christendom[50].
Such are the events which took place before the eruption of the
Black Plague in Europe. Contemporaries have explained them after
their own manner, and have thus, like their posterity, under similar
circumstances, given a proof, that mortals possess neither senses nor
intellectual powers sufficiently acute to comprehend the phenomena
produced by the earth’s organism, much less scientifically to
understand their effects. Superstition, selfishness in a thousand
forms, the presumption of the schools, laid hold of unconnected facts.
They vainly thought to comprehend the whole in the individual, and
perceived not the universal spirit which, in intimate union with the
mighty powers of nature, animates the movements of all existence,
and permits not any phenomenon to originate from isolated causes. To
attempt, five centuries after that age of desolation, to point out the
causes of a cosmical commotion, which has never recurred to an equal
extent,—to indicate scientifically the influences which called forth so
terrific a poison in the bodies of men and animals, exceeds the limits
of human understanding. If we are even now unable, with all the varied
resources of an extended knowledge of nature, to define that condition
of the atmosphere by which pestilences are generated, still less can we
pretend to reason retrospectively from the nineteenth to the fourteenth
century; but if we take a general view of the occurrences, that century
will give us copious information, and, as applicable to all succeeding
times, of high importance.
In the progress of connected natural phenomena, from East to West,
that great law of nature is plainly revealed which has so often and
evidently manifested itself in the earth’s organism, as well as in
the state of nations dependent upon it. In the inmost depths of the
globe, that impulse was given in the year 1333, which in uninterrupted
succession for six-and-twenty years shook the surface of the earth,
even to the western shores of Europe. From the very beginning the
air partook of the terrestrial concussion, atmospherical waters
overflowed the land, or its plants and animals perished under the
scorching heat. The insect tribe was wonderfully called into life, as
if animated beings were destined to complete the destruction which
astral and telluric powers had begun. Thus did this dreadful work of
nature advance from year to year; it was a progressive infection of the
Zones, which exerted a powerful influence both above and beneath the
surface of the earth; and after having been perceptible in slighter
indications, at the commencement of the terrestrial commotions in
China, convulsed the whole earth.
The nature of the first plague in China is unknown. We have no certain
intelligence of the disease, until it entered the western countries of
Asia. Here it shewed itself as the oriental plague with inflammation
of the lungs; in which form it probably also may have begun in China,
that is to say, as a malady which spreads, more than any other,
by contagion—a contagion, that, in ordinary pestilences, requires
immediate contact, and only under unfavourable circumstances of rare
occurrence is communicated by the mere approach to the sick. The share
which this cause had in the spreading of the plague over the whole
earth, was certainly very great: and the opinion that the Black Death
might have been excluded from Western Europe, by good regulations,
similar to those which are now in use, would have all the support of
modern experience, provided it could be proved that this plague had
been actually imported from the East; or that the oriental plague in
general, whenever it appears in Europe, has its origin in Asia or
Egypt. Such a proof, however, can by no means be produced so as to
enforce conviction; for it would involve the impossible assumption,
either that there is no essential difference between the degree of
civilization of the European nations, in the most ancient and in modern
times, or that detrimental circumstances, which have yielded only to
the civilization of human society and the regular cultivation of
countries, could not formerly keep up the glandular plague.
The plague was, however, known in Europe before nations were united
by the bonds of commerce and social intercourse[51]; hence there is
ground for supposing that it sprung up spontaneously, in consequence
of the rude manner of living and the uncultivated state of the earth;
influences which peculiarly favour the origin of severe diseases. Now,
we need not go back to the earlier centuries, for the 14th itself,
before it had half expired, was visited by five or six pestilences[52].
If, therefore, we consider the peculiar property of the plague, that,
in countries which it has once visited, it remains for a long time
in a milder form, and that the epidemic influences of 1342, when it
had appeared for the last time, were particularly favourable to its
unperceived continuance, till 1348, we come to the notion, that in
this eventful year also, the germs of plague existed in Southern
Europe, which might be vivified by atmospherical deteriorations; and
that thus, at least in part, the Black Plague may have originated in
Europe itself. The corruption of the atmosphere came from the East; but
the disease itself came not upon the wings of the wind, but was only
excited and increased by the atmosphere where it had previously existed.
This source of the Black Plague was not, however, the only one; for,
far more powerful than the excitement of the latent elements of the
plague by atmospheric influences, was the effect of the contagion
communicated from one people to another, on the great roads, and
in the harbours of the Mediterranean. From China, the route of the
caravans lay to the north of the Caspian Sea, through Central Asia,
to Tauris. Here ships were ready to take the produce of the East to
Constantinople, the capital of commerce, and the medium of connexion
between Asia, Europe and Africa[53]. Other caravans went from India
to Asia Minor, and touched at the cities south of the Caspian Sea,
and lastly from Bagdad, through Arabia to Egypt; also the maritime
communication on the Red Sea, from India to Arabia and Egypt, was
not inconsiderable. In all these directions contagion made its way;
and doubtless, Constantinople and the harbours of Asia Minor, are to
be regarded as the foci of infection; whence it radiated to the most
distant seaports and islands.
To Constantinople, the plague had been brought from the northern coast
of the Black Sea[54], after it had depopulated the countries between
those routes of commerce; and appeared as early as 1347, in Cyprus,
Sicily, Marseilles and some of the seaports of Italy. The remaining
islands of the Mediterranean, particularly Sardinia, Corsica and
Majorca, were visited in succession. Foci of contagion existed also
in full activity along the whole southern coast of Europe; when, in
January 1348, the plague appeared in Avignon[55], and in other cities
in the south of France and north of Italy, as well as in Spain.
The precise days of its eruption in the individual towns, are no longer
to be ascertained; but it was not simultaneous; for in Florence, the
disease appeared in the beginning of April[56]; in Cesena, the 1st
of June[57]; and place after place was attacked throughout the whole
year; so that the plague, after it had passed through the whole of
France and Germany, where, however, it did not make its ravages until
the following year, did not break out till August, in England; where
it advanced so gradually, that a period of three months elapsed before
it reached London[58]. The northern kingdoms were attacked by it in
