Dope.
Okay. Forward to our next tableau.

�The earthquake began at 9:30 on November 1st, 1755, and was centered in the Atlantic Ocean, about 200 km WSW of Cape St. Vincent.� Geologists call it a slip � there was a slip between two tectonic plates. It might have been the greatest earthquake in recorded history. Immanuel Kant, writing about it latter, believed that atmospheric phenomena prophesied that something was up:

I look upon the prelude of the subterranean inflammation, that after-
wards grew so amazing, to be the atmospheric phenomenon which was
perceived at Locarno in Switzerland on the 14th October last year at 8
o'clock in the morning. A warm vapour, as if coming out of an oven, dif-
fused itself and in two hours turned into a red fog, which towards evening
occasioned a rain red as blood, that, when it was caught, deposited 1/9 of a
reddish gluey sediment. The snow six feet deep was likewise tinged red.
This purple rain was perceived [at] 40 hours, [to extend] about
20 German miles in quadratum, yes, even to Schwaben. On this atmo-
spheric phenomenon followed unnatural downpours, that in three
days gave 23 inches of water,39 which is more than falls throughout the
whole year in a country of a moderately damp nature. This rain continued
over 14 days, though not always with the same violence. The rivers in
Lombardy that have their source in the mountains of Switzerland, as also
the Rhone, swelled with water and overflowed their banks. From this time
prevailed in the air frightful hurricanes, which raged everywhere furiously.
In the middle of November such a purple rain still fell in Ulm, and the
disorder in the atmosphere, the whirlwinds in Italy, [and] the extremely wet
weather continued.

Readers are begged to notice the reference to purple rain. Bet you didn�t know Prince was an ardent fan of Immanuel Kant�s, did you?

Three earthwaves radiated out, the first one hitting Lisbon about 10, and pretty much destroying the lower part of the city. Since it was a feast day, a good part of the population was in church. Marion Kaplan, in her book on Portugal, quotes the contemporary (and, I must say, unlikely sounding) report of a nun: � Itt began like the rattleing of Coaches� I look about me and see the Walls a-shaking and a falling down, then I up and took to my heells, with Jesus in my mouth.�

The third wave hit the upper part of Lisbon, the wealthier neighborhoods, around 12. By this time the devastation in the lower part of the city had been added to by the conflagration that was probably the result of the candles burning in Lisbon�s several churches that day � that was the speculation of contemporaries. To complete the charmed circle of cursed elements, the survivors from the first two shocks had, instinctively, rushed to the harbor, only to find themselves scrambling with human speed to escape the tsunami that came in, it is estimated, at about 6 meters.

�Immediately after the earthquake, many inhabitants of Lisbon looked for safety on the sea by boarding ships moored on the river. But about 30 minutes after the quake, a large wave swamped the area near Bugie Tower on the mouth of the Tagus. The area between Junqueria and Alcantara in the western part of the city was the most heavily damaged by the wave, but further destruction occurred upstream. The Cais de Pedra at Rerreiro do Paco and part of the nearby custom house were flattened.
�A total of three waves struck the shore, each dragging people and debris out to sea and leaving exposed large stretches of the river bottom. In front of the Terreiro do Paco, the maximum height of the waves was estimated at 6 meters. Boats overcrowded with refugees capsized and sank. In the town Cascais, some 30 km west of Lisbon, the waves wrecked several boats and when the water withdrew, large stretches of sea bottom were left uncovered. In coastal areas such as Peniche, situated about 80 km north of Lisbon, many people were killed by the tsunami. In Setubal, 30 km south of Lisbon, the water reached the first floor of buildings. �

One of the remarkable things about the Lisbon quake is that there are still disputes about how much damage it actually did. Here�s an account, appended to a book about the San Francisco earthquake, that gives one estimate of the quake�s magnitude:

�The most distinguishing peculiarities of this earthquake were the
swallowing up of the mole, and the vast extent of the earth's
surface over which the shocks were felt. Several of the highest
mountains in Portugal were violently shaken, and rent at their
summits; huge masses falling from them into the neighboring
valleys. These great fractures gave rise to immense volumes of
dust, which at a distance were mistaken for smoke by those who
beheld them. Flames were also said to have been observed: but if
there were any such, they were probably electrical flashes produced
by the sudden rupture of the rocks.

The portion of the earth's surface convulsed by this earthquake is
estimated by Humboldt to have been four times greater than the
whole extent of Europe. The shocks were felt not only over the
Spanish peninsula, but in Morocco and Algeria they were nearly as
violent. At a place about twenty-four miles from the city of
Morocco, there is said to have occurred a catastrophe much
resembling what took place at the Lisbon mole. A great fissure
opened in the earth, and an entire village, with all its
inhabitants, upwards of 8,000 in number, were precipitated into the
gulf, which immediately closed over its prey.�

Reverand Charles Davy wrote a fine firsthand account of the quake. It is at the much to lauded Fordham history site:

Upon this I threw down my pen---and started upon my feet, remaining a moment in suspense, whether I should stay in the apartment or run into the street, as the danger in both places seemed equal; and still flattering myself that this tremor might produce no other effects than such inconsiderable ones as had been felt at Madeira; but in a moment I was roused from my dream, being instantly stunned with a most horrid crash, as if every edifice in the city had tumbled down at once. The house I was in shook with such violence, that the upper stories immediately fell; and though my apartment (which was the first floor) did not then share the same fate, yet everything was thrown out of its place in such a manner that it was with no small difficulty I kept my feet, and expected nothing less than to be soon crushed to death, as the walls continued rocking to and fro in the frightfulest manner, opening in several places; large stones falling down on every side from the cracks, and the ends of most of the rafters starting out from the roof. To add to this terrifying scene, the sky in a moment became so gloomy that I could now distinguish no particular object; it was an Egyptian darkness indeed, such as might be felt; owing, no doubt, to the prodigious clouds of dust and lime raised from so violent a concussion, and, as some reported, to sulphureous exhalations, but this I cannot affirm; however, it is certain I found myself almost choked for near ten minutes.
I hastened out of the house and through the narrow streets, where the buildings either were down or were continually falling, and climbed over the ruins of St. Paul's Church to get to the river's side, where I thought I might find safety. Here I found a prodigious concourse of people of both sexes, and of all ranks and conditions, among whom I observed some of the principal canons of the patriarchal church, in their purple robes and rochets, as these all go in the habit of bishops; several priests who had run from the altars in their sacerdotal vestments in the midst of their celebrating Mass; ladies half dressed, and some without shoes; all these, whom their mutual dangers had here assembled as to a place of safety, were on their knees at prayers, with the terrors of death in their countenances, every one striking his breast and crying out incessantly, Miserecordia meu Dios! . . . In the midst of our devotions, the second great shock came on, little less violent than the first, and completed the ruin of those buildings which had been already much shattered."



In the aftermath of the quake, there was a brief period of anarchy. With the flames consuming half the town�s goods, the other half became fair game for the prisoners who had escaped from their cells, due to the collapse of the penitentiary. The king�s prime minister, the Marques de Pombal, a figure of xemplary Englightenment views, solved the problem of pillage by erecting gallows in a circle around the shattered hulk of Lisbon and hanging as many thieves as his soldiers could catch. He solved the problem of moral, which was deepened by the fervent call to repentence of several priests, by kicking the Jesuits out of Portugal. Both instances of public policy were applauded by the philosophes.

Finally, here�s a letter, sent by Voltaire to the M. Tronchin on Novemeber 24th, 1755:

Les D�lices, November 24, 1755
This is indeed a cruel piece of natural philosophy! We shall find it difficult to discover how the laws of movement operate in such fearful disasters in the best of all possible worlds-- where a hundred thousand ants, our neighbours, are crushed in a second on our ant-heaps, half, dying undoubtedly in inexpressible agonies, beneath d�bris from which it was impossible to extricate them, families all over Europe reduced to beggary, and the fortunes of a hundred merchants -- Swiss, like yourself -- swallowed up in the ruins of Lisbon. What a game of chance human life is! What will the preachers say -- especially if the Palace of the Inquisition is left standing! I flatter myself that those reverend fathers, the Inquisitors, will have been crushed just like other people. That ought to teach men not to persecute men: for, while a few sanctimonious humbugs are burning a few fanatics, the earth opens and swallows up all alike. I believe it is our mountains which save us from earthquakes.

Enough for one day.
