The Notebooks of Leonardo Da Vinci (37 page)

608.

Let the dark and gloomy air be seen buffeted by the rush of contrary
winds and dense from the continued rain mingled with hail and
bearing hither and thither an infinite number of branches torn from
the trees and mixed with numberless leaves. All round may be seen
venerable trees, uprooted and stripped by the fury of the winds; and
fragments of mountains, already scoured bare by the torrents,
falling into those torrents and choking their valleys till the
swollen rivers overflow and submerge the wide lowlands and their
inhabitants. Again, you might have seen on many of the hill-tops
terrified animals of different kinds, collected together and subdued
to tameness, in company with men and women who had fled there with
their children. The waters which covered the fields, with their
waves were in great part strewn with tables, bedsteads, boats and
various other contrivances made from necessity and the fear of
death, on which were men and women with their children amid sounds
of lamentation and weeping, terrified by the fury of the winds which
with their tempestuous violence rolled the waters under and over and
about the bodies of the drowned. Nor was there any object lighter
than the water which was not covered with a variety of animals
which, having come to a truce, stood together in a frightened
crowd—among them wolves, foxes, snakes and others—fleing from
death. And all the waters dashing on their shores seemed to be
battling them with the blows of drowned bodies, blows which killed
those in whom any life remained [19]. You might have seen
assemblages of men who, with weapons in their hands, defended the
small spots that remained to them against lions, wolves and beasts
of prey who sought safety there. Ah! what dreadful noises were heard
in the air rent by the fury of the thunder and the lightnings it
flashed forth, which darted from the clouds dealing ruin and
striking all that opposed its course. Ah! how many you might have
seen closing their ears with their hands to shut out the tremendous
sounds made in the darkened air by the raging of the winds mingling
with the rain, the thunders of heaven and the fury of the
thunder-bolts. Others were not content with shutting their eyes, but
laid their hands one over the other to cover them the closer that
they might not see the cruel slaughter of the human race by the
wrath of God. Ah! how many laments! and how many in their terror
flung themselves from the rocks! Huge branches of great oaks loaded
with men were seen borne through the air by the impetuous fury of
the winds. How many were the boats upset, some entire, and some
broken in pieces, on the top of people labouring to escape with
gestures and actions of grief foretelling a fearful death. Others,
with desperate act, took their own lives, hopeless of being able to
endure such suffering; and of these, some flung themselves from
lofty rocks, others strangled themselves with their own hands, other
seized their own children and violently slew them at a blow; some
wounded and killed themselves with their own weapons; others,
falling on their knees recommended themselves to God. Ah! how many
mothers wept over their drowned sons, holding them upon their knees,
with arms raised spread out towards heaven and with words and
various threatening gestures, upbraiding the wrath of the gods.
Others with clasped hands and fingers clenched gnawed them and
devoured them till they bled, crouching with their breast down on
their knees in their intense and unbearable anguish. Herds of
animals were to be seen, such as horses, oxen, goats and swine
already environed by the waters and left isolated on the high peaks
of the mountains, huddled together, those in the middle climbing to
the top and treading on the others, and fighting fiercely
themselves; and many would die for lack of food. Already had the
birds begun to settle on men and on other animals, finding no land
uncovered which was not occupied by living beings, and already had
famine, the minister of death, taken the lives of the greater number
of the animals, when the dead bodies, now fermented, where leaving
the depth of the waters and were rising to the top. Among the
buffeting waves, where they were beating one against the other, and,
like as balls full of air, rebounded from the point of concussion,
these found a resting place on the bodies of the dead. And above
these judgements, the air was seen covered with dark clouds, riven
by the forked flashes of the raging bolts of heaven, lighting up on
all sides the depth of the gloom.

The motion of the air is seen by the motion of the dust thrown up by
the horse's running and this motion is as swift in again filling up
the vacuum left in the air which enclosed the horse, as he is rapid
in passing away from the air.

Perhaps it will seem to you that you may reproach me with having
represented the currents made through the air by the motion of the
wind notwithstanding that the wind itself is not visible in the air.
To this I must answer that it is not the motion of the wind but only
the motion of the things carried along by it which is seen in the
air.

THE DIVISIONS. [Footnote 76: These observations, added at the bottom
of the page containing the full description of the doluge seem to
indicate that it was Leonardo's intention to elaborate the subject
still farther in a separate treatise.]

Darkness, wind, tempest at sea, floods of water, forests on fire,
rain, bolts from heaven, earthquakes and ruins of mountains,
overthrow of cities [Footnote 81:
Spianamenti di citta
(overthrow
of cities). A considerable number of drawings in black chalk, at
Windsor, illustrate this catastrophe. Most of them are much rubbed;
one of the least injured is reproduced at Pl. XXXIX. Compare also
the pen and ink sketch Pl. XXXVI.].

Whirlwinds which carry water [spouts] branches of trees, and men
through the air.

Boughs stripped off by the winds, mingling by the meeting of the
winds, with people upon them.

Broken trees loaded with people.

Ships broken to pieces, beaten on rocks.

Flocks of sheep. Hail stones, thunderbolts, whirlwinds.

People on trees which are unable to to support them; trees and
rocks, towers and hills covered with people, boats, tables, troughs,
and other means of floating. Hills covered with men, women and
animals; and lightning from the clouds illuminating every thing.

[Footnote: This chapter, which, with the next one, is written on a
loose sheet, seems to be the passage to which one of the compilers
of the Vatican copy alluded when he wrote on the margin of fol. 36:
"
Qua mi ricordo della mirabile discritione del Diluuio dello
autore.
" It is scarcely necessary to point out that these chapters
are among those which have never before been published. The
description in No. 607 may be regarded as a preliminary sketch for
this one. As the MS. G. (in which it is to be found) must be
attributed to the period of about 1515 we may deduce from it the
approximate date of the drawings on Pl. XXXIV, XXXV, Nos. 2 and 3,
XXXVI and XXXVII, since they obviously belong to this text. The
drawings No. 2 on Pl. XXXV are, in the original, side by side with
the text of No. 608; lines 57 to 76 are shown in the facsimile. In
the drawing in Indian ink given on Pl. XXXIV we see Wind-gods in the
sky, corresponding to the allusion to Aeolus in No. 607 1.
15.-Plates XXXVI and XXXVII form one sheet in the original. The
texts reproduced on these Plates have however no connection with the
sketches, excepting the sketches of clouds on the right hand side.
These texts are given as No. 477. The group of small figures on Pl.
XXXVII, to the left, seems to be intended for a '
congregatione
d'uomini.
' See No. 608, 1. 19.]

Let there be first represented the summit of a rugged mountain with
valleys surrounding its base, and on its sides let the surface of
the soil be seen to slide, together with the small roots of the
bushes, denuding great portions of the surrounding rocks. And
descending ruinous from these precipices in its boisterous course,
let it dash along and lay bare the twisted and gnarled roots of
large trees overthrowing their roots upwards; and let the mountains,
as they are scoured bare, discover the profound fissures made in
them by ancient earthquakes. The base of the mountains may be in
great part clothed and covered with ruins of shrubs, hurled down
from the sides of their lofty peaks, which will be mixed with mud,
roots, boughs of trees, with all sorts of leaves thrust in with the
mud and earth and stones. And into the depth of some valley may have
fallen the fragments of a mountain forming a shore to the swollen
waters of its river; which, having already burst its banks, will
rush on in monstrous waves; and the greatest will strike upon and
destroy the walls of the cities and farmhouses in the valley [14].
Then the ruins of the high buildings in these cities will throw up a
great dust, rising up in shape like smoke or wreathed clouds against
the falling rain; But the swollen waters will sweep round the pool
which contains them striking in eddying whirlpools against the
different obstacles, and leaping into the air in muddy foam; then,
falling back, the beaten water will again be dashed into the air.
And the whirling waves which fly from the place of concussion, and
whose impetus moves them across other eddies going in a contrary
direction, after their recoil will be tossed up into the air but
without dashing off from the surface. Where the water issues from
the pool the spent waves will be seen spreading out towards the
outlet; and there falling or pouring through the air and gaining
weight and impetus they will strike on the water below piercing it
and rushing furiously to reach its depth; from which being thrown
back it returns to the surface of the lake, carrying up the air that
was submerged with it; and this remains at the outlet in foam
mingled with logs of wood and other matters lighter than water.
Round these again are formed the beginnings of waves which increase
the more in circumference as they acquire more movement; and this
movement rises less high in proportion as they acquire a broader
base and thus they are less conspicuous as they die away. But if
these waves rebound from various objects they then return in direct
opposition to the others following them, observing the same law of
increase in their curve as they have already acquired in the
movement they started with. The rain, as it falls from the clouds is
of the same colour as those clouds, that is in its shaded side;
unless indeed the sun's rays should break through them; in that case
the rain will appear less dark than the clouds. And if the heavy
masses of ruin of large mountains or of other grand buildings fall
into the vast pools of water, a great quantity will be flung into
the air and its movement will be in a contrary direction to that of
the object which struck the water; that is to say: The angle of
reflection will be equal to the angle of incidence. Of the objects
carried down by the current, those which are heaviest or rather
largest in mass will keep farthest from the two opposite shores. The
water in the eddies revolves more swiftly in proportion as it is
nearer to their centre. The crests of the waves of the sea tumble to
their bases falling with friction on the bubbles of their sides; and
this friction grinds the falling water into minute particles and
this being converted into a dense mist, mingles with the gale in the
manner of curling smoke and wreathing clouds, and at last it, rises
into the air and is converted into clouds. But the rain which falls
through the atmosphere being driven and tossed by the winds becomes
rarer or denser according to the rarity or density of the winds that
buffet it, and thus there is generated in the atmosphere a moisture
formed of the transparent particles of the rain which is near to the
eye of the spectator. The waves of the sea which break on the slope
of the mountains which bound it, will foam from the velocity with
which they fall against these hills; in rushing back they will meet
the next wave as it comes and and after a loud noise return in a
great flood to the sea whence they came. Let great numbers of
inhabitants—men and animals of all kinds—be seen driven [54] by
the rising of the deluge to the peaks of the mountains in the midst
of the waters aforesaid.

The wave of the sea at Piombino is all foaming water. [Footnote 55.
56: These two lines are written below the bottom sketch on Pl. XXXV,
3. The MS. Leic. being written about the year 1510 or later, it does
not seem to me to follow that the sketches must have been made at
Piombino, where Leonardo was in the year 1502 and possibly returned
there subsequently (see Vol. II. Topographical notes).]

Of the water which leaps up from the spot where great masses fall on
its surface. Of the winds of Piombino at Piombino. Eddies of wind
and rain with boughs and shrubs mixed in the air. Emptying the boats
of the rain water.

[Footnote: The sketches on Pl. XXXV 3 stand by the side of lines 14
to 54.]

Of depicting natural phenomena (610. 611).

The tremendous fury of the wind driven by the falling in of the
hills on the caves within—by the falling of the hills which served
as roofs to these caverns.

A stone flung through the air leaves on the eye which sees it the
impression of its motion, and the same effect is produced by the
drops of water which fall from the clouds when it [16] rains.

[17] A mountain falling on a town, will fling up dust in the form of
clouds; but the colour of this dust will differ from that of the
clouds. Where the rain is thickest let the colour of the dust be
less conspicuous and where the dust is thickest let the rain be less
conspicuous. And where the rain is mingled with the wind and with
the dust the clouds created by the rain must be more transparent
than those of dust [alone]. And when flames of fire are mingled with
clouds of smoke and water very opaque and dark clouds will be formed
[Footnote 26-28: Compare Pl. XL, 1—the drawing in Indian ink on the
left hand side, which seems to be a reminiscence of his observations
of an eruption (see his remarks on Mount Etna in Vol II).]. And the
rest of this subject will be treated in detail in the book on
painting.
