summit of the mountain and the sun. [Footnote 6: in una eta. This is perhaps a slip of the pen on Leonardo’s part and should be read estate (summer).]

In the mountains of Verona the red marble is found all mixed with cockle shells turned into stone; some of them have been filled at the mouth with the cement which is the substance of the stone; and in some parts they have remained separate from the mass of the rock which enclosed them, because the outer covering of the shell had interposed and had not allowed them to unite with it; while in other places this cement had petrified those which were old and almost stripped the outer skin.

Bridge of Goertz-Wilbach (?).

[Footnote: There is a slight sketch with this text, Leonardo seems to have intended to suggest, with a few pen-strokes, the course of the Isonzo and of the Wipbach in the vicinity of Gorizia (Goerz). He himself says in another place that he had been in Friuli (see No. 1077 1. 19).]

The Appenins (1063-1068).

 

1063.

 

That part of the earth which was lightest remained farthest from the centre of the world; and that part of the earth became the lightest over which the greatest quantity of water flowed. And therefore that part became lightest where the greatest number of rivers flow; like the Alps which divide Germany and France from Italy; whence issue the Rhone flowing Southwards, and the Rhine to the North. The Danube or Tanoia towards the North East, and the Po to the East, with innumerable rivers which join them, and which always run turbid with the soil carried by them to the sea.

The shores of the sea are constantly moving towards the middle of the sea and displace it from its original position. The lowest portion of the Mediterranean will be reserved for the bed and current of the Nile, the largest river that flows into that sea. And with it are grouped all its tributaries, which at first fell into the sea; as may be seen with the Po and its tributaries, which first fell into that sea, which between the Appenines and the German Alps was united to the Adriatic sea.

That the Gallic Alps are the highest part of Europe.

And of these I found some in the rocks of the high Appenines and mostly at the rock of La Vernia. [Footnote 6: Sasso della Vernia. The frowning rock between the sources of the Arno and the Tiber, as Dante describes this mountain, which is 1269 metres in height.

This note is written by the side of that given as No. 1020; but their connection does not make it clear what Leonardo’s purpose was in writing it.]

 

1065.

 

At Parma, at ‘La Campana’ on the twenty-fifth of October 1514. [Footnote 2: Capano, an Inn.]

A note on the petrifactions, or fossils near Parma will be found under No. 989.]

 

1066.

 

A method for drying the marsh of Piombino. [Footnote: There is a slight sketch with this text in the original.—Piombino is also mentioned in Nos. 609, l. 55-58 (compare Pl. XXXV, 3, below). Also in No. 1035.]

 

1067.

 

The shepherds in the Romagna at the foot of the Apennines make peculiar large cavities in the mountains in the form of a horn, and on one side they fasten a horn. This little horn becomes one and the same with the said cavity and thus they produce by blowing into it a very loud noise. [Footnote: As to the Romagna see also No. 1046.]

 

1068.

 

A spring may be seen to rise in Sicily which at certain times of the year throws out chesnut leaves in quantities; but in Sicily chesnuts do not grow, hence it is evident that that spring must issue from some abyss in Italy and then flow beneath the sea to break forth in Sicily. [Footnote: The chesnut tree is very common in Sicily. In writing cicilia Leonardo meant perhaps Cilicia.]

FRANCE.

GERMANY. FRANCE.

a. Austria, a. Picardy. b. Saxony. b. Normandy. c. Nuremberg. c. Dauphine. d. Flanders.

SPAIN.

a. Biscay. b. Castille. c. Galicia. d. Portugal. e. Taragona. f. Granada.

[Footnote: Two slightly sketched maps, one of Europe the other of Spain, are at the side of these notes.]

Perpignan. Roanne. Lyons. Paris. Ghent. Bruges. Holland.

[Footnote: Roana does not seem to mean here Rouen in Normandy, but is probably Roanne (Rodumna) on the upper Loire, Lyonnais (Dep. du Loire). This town is now unimportant, but in Leonardo’s time was still a place of some consequence.]

At Bordeaux in Gascony the sea rises about 40 braccia before its ebb, and the river there is filled with salt water for more than a hundred and fifty miles; and the vessels which are repaired there rest high and dry on a high hill above the sea at low tide. [Footnote 2: This is obviously an exaggeration founded on inaccurate information. Half of 150 miles would be nearer the mark.]

 

1072.

 

The Rhone issues from the lake of Geneva and flows first to the West and then to the South, with a course of 400 miles and pours its waters into the Mediterranean.

c d is the garden at Blois; a b is the conduit of Blois, made in France by Fra Giocondo, b c is what is wanting in the height of that conduit, c d is the height of the garden at Blois, e f is the siphon of the conduit, b c, e f, f g is where the siphon discharges into the river. [Footnote: The tenor of this note (see lines 2 and 3) seems to me to indicate that this passage was not written in France, but was written from oral information. We have no evidence as to when this note may have been written beyond the circumstance that Fra Giocondo the Veronese Architect left France not before the year 1505. The greater part of the magnificent Chateau of Blois has now disappeared. Whether this note was made for a special purpose is uncertain. The original form and extent of the Chateau is shown in Androvet, Les plus excellents Bastiments de France, Paris MDCVII, and it may be observed that there is in the middle of the garden a Pavilion somewhat similar to that shown on Pl. LXXXVIII No. 7.

See S. DE LA SAUSSAYE, Histoire du Chateau de Blois 4eme edition Blois et Paris p. 175: En mariant sa fille ainee a Francois, comte d’Angouleme, Louis XII lui avait constitue en dot les comtes de Blois, d’Asti, de Coucy, de Montfort, d’Etampes et de Vertus. Une ordonnance de Francois I. lui laissa en 1516 _l’administration du comte de Blois.

Le roi fit commencer, dans la meme annee, les travaux de celle belle partie du chateau, connue sous le nom d’aile de Francois I, et dont nous avons donne la description au commencement de ce livre. Nous trouvons en effet, dans les archives du Baron de Foursanvault, une piece qui en fixe parfaitement la date. On y lit: “Je, Baymon Philippeaux, commis par le Roy a tenir le compte et fair le payement des bastiments, ediffices et reparacions que le dit seigneur fait faire en son chastu de Blois, confesse avoir eu et receu … la somme de trois mille livres tournois … le cinquieme jour de juillet, l’an mil cinq cent et seize._ P. 24: Les jardins avaient ete decores avec beaucoup de luxe par les differents possesseurs du chateau. Il ne reste de tous les batiments qu’ils y eleverent que ceux des officiers charges de l’administration et de la culture des jardins, et un pavilion carre en pierre et en brique flanque de terrasses a chacun de ses angles. Quoique defigure par des mesures elevees sur les terrasses, cet edifice est tris-digne d’interet par l’originalite du plan, la decoration architecturale et le souvenir d’Anne de Bretagne qui le fit construire._ Felibien describes the garden as follows: _Le jardin haut etait fort bien dresse par grands compartimens de toutes sortes de figures, avec des allees de meuriers blancs et des palissades de coudriers. Deux grands berceaux de charpenterie separoient toute la longueur et la largeur du jardin, et dans les quatres angles des allees, ou ces berceaux se croissent, il y auoit 4 cabinets, de mesme charpenterie … Il y a pas longtemps qu’il y auoit dans ce mesme jardin, a l’endroit ou se croissent les allees du milieu, un edifice de figure octogone, de plus de 7 thoises de diametre et de plus de neuf thoises de haut; avec 4 enfoncements en forme de niches dans les 4 angles des allies. Ce bastiment…. esloit de charpente mais d’un extraordinairement bien travaille. On y voyait particulierement la cordiliere qui regnati tout autour en forme de cordon. Car la Reyne affectait de la mettre nonseulement a ses armes et a ses chiffres mais de la faire representer en divers manieres dans tous les ouvrages qu’on lui faisait pour elle … le bastiment estati couvert en forme de dome qui dans son milieu avait encore un plus petit dome, ou lanterne vitree au-dessus de laquelle estait une figure doree representant Saint Michel. Les deux domes estoient proprement couvert d’ardoise et de plomb dore par dehors; par dedans ils esloient lambrissez d’une menuiserie tres delicate. Au milieu de ce Salon il y avait un grand bassin octogone de marbre blanc, dont toutes les faces estoient enrichies de differentes sculptures, avec les armes et les chiffres du Roy Louis XII et de la Reine Anne, Dans ce bassin il y en avait un autre pose sur un piedestal lequel auoit sept piedz de diametre. Il estait de figure ronde a godrons, avec des masques et d’autres ornements tres scauamment taillez. Du milieu de ce deuxiesme bassin s’y levoit un autre petit piedestal qui portait un troisiesme bassin de trois pieds de diametre, aussy parfaitement bien taille; c’estoit de ce dernier bassin que jallissoit l’eau qui se rependoit en suitte dans les deux autres bassins. Les beaux ouvrages faits d’un marbre esgalement blanc et poli, furent brisez par la pesanteur de tout l’edifice, que les injures de l’air renverserent de fond en comble.]

The river Loire at Amboise.

The river is higher within the bank b d than outside that bank.

The island where there is a part of Amboise.

This is the river that passes through Amboise; it passes at a b c d, and when it has passed the bridge it turns back, against the original current, by the channel d e, b f in contact with the bank which lies between the two contrary currents of the said river, a b, c d, and d e, b f. It then turns down again by the channel f l, g h, n m, and reunites with the river from which it was at first separated, which passes by k n, which makes k m, r t. But when the river is very full it flows all in one channel passing over the bank b d. [Footnote: See Pl. CXV. Lines 1-7 are above, lines 8-10 in the middle of the large island and the word Isola is written above d in the smaller island; a is written on the margin on the bank of the river above 1. I; in the reproduction it is not visible. As may be seen from the last sentence, the observation was made after long study of the river’s course, when Leonardo had resided for some time at, or near, Amboise.]
