[Footnote: I. _Guiliano Gondi_. Ser Piero da Vinci, Leonardo’s father, lived till 1480, in a house belonging to Giuliano Gondi. In 1498 this was pulled down to make room for the fine Palazzo built on the Piazza San Firenze by Giuliano di San Gallo, which still exists. In the _Riassunto del Catasto di Ser Piero da Vinci_, 1480, Leonardo is not mentioned; it is evident therefore that he was living elsewhere. It may be noticed incidentally that in the _Catasto di Giuliano Gondi_ of the same year the following mention is made of his four eldest sons:

_Lionardo mio figliuolo d’eta d’anni 29, non fa nulla, Giovambatista d’eta d’anni 28 in Ghostantinopoli, Billichozo d’eta d’anni 24 a Napoli,
Simone d’eta d’anni 23 in Ungheria.

He himself was a merchant of gold filigree (_facciamo lavorare una bottegha d’arte di seta … facciamo un pocho di trafico a Napoli_}, As he was 59 years old in 1480, he certainly would not have been alive at the time of Leonardo’s death. But Leonardo must have been on intimate terms with the family till the end of his life, for in a letter dated June 1. 1519, in which Fr. Melzi, writing from Amboise, announces Leonardo’s death to Giuliano da Vinci at Florence (see p. 284), he says at the end “_Datemene risposta per i Gondi_” (see UZIELLI, _Ricerche_, passim).

Most of the other names on the list are those of well-known Florentine families.]

and made him a present of the palazzo he had built, when Cardinal, near the church of Santi Apostoli which is now known as the Palazzo Colonna (see GREGOROVIUS, _Gesch. der Stadt Rom._ Vol. VIII, book XIV I, 3. And COPPI, _Mem. Colonnesi p. 251).]

Paolo of Tavechia, to see the marks in the German stones.

[Footnote: This note occurs on a pen and ink drawing made by Leonardo as a sketch for the celebrated large cartoon in the possession of the Royal Academy of Arts, in London. This cartoon is commonly supposed to be identical with that described and lauded by Vasari, which was exhibited in Florence at the time and which now seems to be lost. Mr. Alfred Marks, of Long Ditton, in his valuable paper (read before the Royal Soc. of Literature, June 28, 1882) “On the St. Anne of Leonardo da Vinci”, has adduced proof that the cartoon now in the Royal Academy was executed earlier at Milan. The note here given, which is written on the sheet containing the study for the said cartoon, has evidently no reference to the drawing on which it is written but is obviously of the same date. Though I have not any opening here for discussing this question of the cartoon, it seemed to me important to point out that the character of the writing in this note does not confirm the opinion hitherto held that the Royal Academy cartoon was the one described by Vasari, but, on the contrary, supports the hypothesis put forward by Mr. Marks.]

Notes on


Giacomo came to live with me on St.-Mary Magdalen’s[*1] day, 1490, aged 10 years. The second day I had two shirts cut out for him, a pair of hose, and a jerkin, and when I put aside some money to pay for these things he stole 4 _lire_
the money out of the purse; and I could never make him confess, though I was quite certain of the fact.–Thief, liar, obstinate, glutton.

The day after, I went to sup with Giacomo Andrea, and the said Giacomo supped
for two and did mischief for four; for he brake 3 cruets, spilled the wine, and after this came to sup where I….

Item: on the 7th day of September he
stole a silver point of the value of 22 soldi from Marco [Footnote 6: _Marco_, probably Leonardo’s pupil Marco d’Oggionno; 1470 is supposed to be the date of his
birth and 1540 of his death.

_Che stava con meco._ We may infer from this that he left the master shortly after this, his term of study having perhaps expired.] who was living with me, 4 _lire_ this being of silver; and he took it from his studio, and when the said Marco had searched for it a long while he found it hidden
in the said Giacomo’s box 4 _lire_.

[Footnote: _Il di della Maddalena._ July 22.] Item: on the 26th January following,
I, being in the house of Messer Galeazzo da San Severino [Footnote 9: Galeazza. See No. 718 note.], was arranging the festival for his jousting, and certain footmen having undressed to try on some costumes of wild men for the said festival, Giacomo went to the purse of one of them which lay on the bed with other clothes, 2 lire 4 S, and took out such money as was in it.

Item: when I was in the same house,
Maestro Agostino da Pavia gave to me a Turkish hide to have 2 lire.
a pair of short boots made of it; this Giacomo stole it of me within a month and sold it to a cobbler for 20 soldi, with
which money, by his own confession, he bought anise comfits.

Item: again, on the 2nd April, Giovan Antonio [Footnote 16:Giovan Antonio, probably Beltraffio, 1467 to 1516.] having left a silver point on a drawing of his, Giacomo stole it, and this was of the value of 24 soldi 1 lira 4 S.

The first year-

A cloak, 2 lire,
6 shirts, 4 lire,
3 jerkins, 6 lire,
4 pairs of hose, 7 lire 8 soldi,
1 lined doublet, 5 lire,
24 pairs of shoes, 6 lire 5 soldi,
A cap, l lira,
laces, 1 lira.
[Footnote: Leonardo here gives a detailed account not only of the loss he and others incurred through Giacomo but of the wild tricks of the youth, and we may therefore assume that the note was not made merely as a record for his own use, but as a report to be forwarded to the lad’s father or other responsible guardian.]

On the last day but one of September;

Thursday the 27th day of September
Maestro Tommaso came back and worked for himself until the last day but one of February. On the 18th day of March, 1493, Giulio, a German, came to live with me,–Lucia, Piero, Leonardo.

On the 6th day of October.


On the 1st day of November we settled accounts. Giulio had to pay 4 months;
and Maestro Tommaso 9 months; Maestro Tommaso afterwards made 6 candlesticks,
10 days’ work; Giulio some fire-tongs 15 days work. Then he worked for himself till the 27th May, and worked for me at a lever till the 18th July; then for himself till the 7th of August, and for one day, on the fifteenth, for a lady. Then again for me at 2 locks until the 20th of August.


On the 23rd day of August, 12 lire from Pulisona. On the 14th of March 1494, Galeazzo came to live with me, agreeing to
pay 5 lire a month for his cost paying on the l4th day of each month.

His father gave me 2 Rhenish florins.

On the l4th of July, I had from Galeazze 2 Rhenish florins.


On the l5th day of September Giulio began the lock of my studio 1494.


Saturday morning the 3rd of August 1504 Jacopo the German came to live with me
in the house, and agreed with me that I should charge him a carlino a day.


On the 26th of September Antonio broke his leg; he must rest 40 days.

[Footnote: This note refers possibly to Beltraffio.] 1465.

I left Milan for Rome on the 24th day of September, 1513, with Giovanni [*2], Francesco di Melzi [*3], Salai, Lorenzo and il Fanfoia.


On the 3rd day of January.

Benedetto carne on the 17th of October; he stayed with me two months and 13 days of last year [*4], in which time he earned 38 lire, 18 soldi and 8 dinari; he had of this 26 lire and 8 soldi, and there remains to be paid for the past year 12 lire 10 soldi.

Giodatti (?) came on the 8th day of September, at 4 soldi a month, and stayed with
me 3 months and 24 days, and earned 59 lire 14 soldi and 8 dinari; he has had 43 lire, 4 soldi, there remains to pay 16 lire, 10 soldi and 8 dinari.

*1465. 2. _Giovan;_ it is not likely that Leonardo should have called Giovan’ Antonio Beltraffio at one time Giovanni, as in this note and another time Antonio, as in No. 1464 while in No. 1458 l. 16 we find _Giovan’Antonio_, and in No. 1436, l.6 _Beltraffio_. Possibly the Giovanni here spoken of is Leonardo’s less known pupil Giovan Pietrino (see No. 1467, 5).

2. 3. _Francesco de’ Melzi_ is often mentioned, see Nos. 1350.

3. _Salai_. See No. 1519 note.

4. _Lorenzo_. See No. 1351, l. 10 (p. 408). Amoretti gives the following note in _Mem. Stor. XXIII:_ 1505. _Martedi-sera a di 14 d’aprile. Venne Lorenzo a stare con mecho: disse essere d’eta d’anni 17 .. a di 15 del detto aprile ebbi scudi 25 d’oro dal chamerlingo di Santa Maria nuova._ This, he asserts is derived from a MS. marked S, in quarto. This MS. seems to have vanished and left no trace behind; Amoretti himself had not seen it, but copied from a selection of extracts made by Oltrocchi before the Leonardo MSS. were conveyed to Paris on the responsibility of the first French Republic. Lorenzo, by this, must have been born in 1487. The sculptor Lorenzetto was born in 1490. Amoretti has been led by the above passage to make the following absurd observations:

_Cotesto Lorenzo, che poi gli fu sempre compagno, almeno sin che stette in Italia, sarebb’ egli Lorenzo Lotto bergamasco? Sappiamo essere stato questo valente dipintore uno de’ bravi scolari del Vinci_ (?).

_Il Fafoia_, perhaps a nickname. Cesare da Sesto, Leonardo’s pupil, seems to have been in Rome in these years, as we learn from a drawing by him in the Louvre.

1466. This seems to be an account for two assistants. The name of the second is scarcely legible. The year is not given. The note is nevertheless of chronological value. The first line tells us the date when the note was registered, January 3d, and the* C.A.F. 279a; 855a]

This, as he then intended, was to come out after the publication of this work of mine. After the much regretted death of the elder Marchese, his son, the Marchese Gioachino d’Adda was so liberal as to place these MS. materials at my disposal for the present work, through the kind intervention of Signor Gustavo Frizzoni. The following passages, with the initials G. d’A. are prints from the valuable notes in that publication, the MS. additions I have marked*.

****below must belong to previous page’s footnotes*** observations that follow refer to events of the previous month ‘of last year’ (dell’ anno passato). Leonardo cannot therefore have written thus in Florence where the year was, at that period, calculated as beginning in the month of March (see Vol. I, No. 4, note 2). He must then have been in Milan. What is more important is that we thus learn how to date the beginning of the year in all the notes written at Milan. This clears up Uzielli’s doubts: A Milano facevasi cominciar l’anno ab incarnatione, cioe il 25 Marzo e a nativitate, cioe il 25 Decembre. Ci sembra probabile che Leonardo dovesse prescegliere lo stile che era in uso a Firenze. (Ricerche, p. 84, note.)

The Archimedes belonging to the Bishop of Padua.


Archimedes gave the quadrature of a poly- gonal figure, but not of the circle. Hence Archimedes never squared any figure with curved sides. He squared the circle minus the smallest portion that the intellect can conceive, that is the smallest point visible.


If any man could have discovered the
utmost powers of the cannon, in all its various forms and have given such a secret to the Romans, with what rapidity would
they have conquered every country and have vanquished every army, and what reward could have been great enough for such a service! Archimedes indeed, although he had greatly damaged the Romans in the siege of Syra- cuse, nevertheless did not fail of being offered great rewards from these very Romans; and when Syracuse was taken, diligent search was made for Archimedes; and he being found
dead greater lamentation was made for him by the Senate and people of Rome than if they had lost all their army; and they
did not fail to honour him with burial and with a statue. At their head was Marcus
Marcellus. And after the second destruction of Syracuse, the sepulchre of Archimedes was found again by Cato[25], in the ruins of a temple. So Cato had the temple restored and the sepulchre he so highly honoured….
Whence it is written that Cato said that he was not so proud of any thing he had done as of having paid such honour to Archimedes.

1476. Where Leonardo found the statement that Cato had found and restored the tomb of Archi- medes, I do not know. It is a merit that Cicero claims as his own (Tusc. V, 23) and certainly with a full right to it. None of Archimedes’ biographers -not even the diligent Mazzucchelli, mentions any version in which Cato is named. It is evidently a

slip of the memory on Leonardo’s part. Besides, according to the passage in Cicero, the grave was not found ‘nelle mine ffun tempio’-which is highly improbable as relating to a Greek-but in an open spot (H. MULLER-STROBING).–See too, as to Archi- medes, No. 1417.

The highest good is wisdom, the chief evil is suffering in the body. Because, as we are composed of two things, that is soul and body, of which the first is the better, the body is the inferior; wisdom belongs to the better part, and the chief evil belongs to the worse part and is the worst of all. As the best thing of all in the soul is
wisdom, so the worst in the body is suf- fering. Therefore just as bodily pain is the chief evil, wisdom is the chief good of the soul, that is with the wise man; and nothing else can be compared with it.

Demetrius was wont to say that there was no difference between the speech and words of the foolish and ignorant, and the noises and rumblings of the wind in an inflated stomach.

The catapult, as we are told by Nonius and Pliny, is a machine devised by those &c. [Footnote: _Plinius_, see No. 946.]


I have found in a history of the Spaniards that in their wars with the English Archimedes of Syracuse who at that time was living
at the court of Ecliderides, King of the Cirodastri. And in maritime warfare he ordered that the ships should have tall masts, and that on their tops there should be a spar fixed [Footnote 6: Compare No. 1115.] of 40 feet long and one third of a foot thick. At one end of this was a small grappling iron and at the other a counterpoise; and there was also attached 12 feet of chain; and, at the end of this chain, as much rope as would reach from the chain to the base of the top, where it was fixed with a small rope; from this base it ran down to the bottom of the mast where a
very strong spar was attached and to this was fastened the end of the rope. But to go on to the use of his machine; I say that below this grappling iron was a fire [Footnote 14: Compare No. 1128.] which, with tremendous noise, threw down its rays and a shower of burning pitch; which, pouring down on the [enemy’s] top, compelled the men who were in it to abandon the top
to which the grappling-iron had clung. This was hooked on to the edges of the top
and then suddenly the cord attached at the base of the top to support the cord which went from the grappling iron, was cut, giving way and drawing in the enemy’s ship; and if the anchor–was cast …
[Footnote: Archimedes never visited Spain, and the names here mentioned cannot be explained. Leonardo seems to quote here from a book, perhaps by some questionable mediaeval writer. Prof. C.

Messer Vincenzio Aliprando, who lives near the Inn of the Bear, has Giacomo
Andrea’s Vitruvius.

L. 53b]


Vitruvius says that small models are of no avail for ascertaining the effects of large ones; and I here propose to prove that
this conclusion is a false one. And chiefly by bringing forward the very same argument which led him to this conclusion; that is, by an experiment with an auger. For he proves that if a man, by a certain exertion of
strength, makes a hole of a given diameter, and afterwards another hole of double the diameter, this cannot be made with only
double the exertion of the man’s strength, but needs much more. To this it may very well be answered that an auger

L. 53a]


of double the diameter cannot be
moved by double the exertion, be-
cause the superficies of a body of
the same form but twice as large has four times the extent of the superficies of the smaller, as is shown in the two
figures a and n.

Vitruvius, measuring miles by means of the repeated revolutions of the wheels which move vehicles, extended over many Stadia the lines of the circumferences of the circles of these wheels. He became aware of them by the animals that moved the vehicles. But he did not discern that this was a means of finding a square equal to a circle. This was first done by Archimedes of Syracuse, who by multiplying the second diameter of a circle by half its circumference produced a rectangular quadrilateral equal figure to the circle.

*7. _Al fattore._ Il Fattore, was, as is well known, the nick-name of Giovanni Franceso Penni, born in Florence in 1486, and subsequently a pupil of Raphael’s. According to Vasari he was known by it
even as a boy. Whether he is spoken of in this passage, or whether the word Fattore should be translated literally, I will not undertake to decide. The latter seems to me more probably right.

[Footnote: The meaning of this document, which is very difficult to decipher, and is written in unintelligible
Latin, is, that Leonardo di Mansuetis recommends the Rev. Mair of Nusdorf, chaplain at Vienna, to some third person; and says also that something, which had to be proved, has been proved. The rest of the passages on the same leaf are undoubtedly in Leonardo’s hand. (Nos. 483, 661, 519, 578, 392, 582, 887 and 894.)]

Johannes Antonius di Johannes Ambro-
sius de Bolate. He who lets time pass and does not grow in virtue, the more I think of it the more I grieve. No man has it in him to be virtuous who will give up honour for gain. Good fortune is valueless to him who knows not toil. The man becomes
happy who follows Christ. There is no perfect gift without great suffering. Our glories and our triumphs pass away. Foul lust, and dreams, and luxury, and sloth have banished every virtue from the world; so that our Nature, wandering and perplexed, has almost lost the old and better track. Henceforth it were well to rouse thyself from sleep. The master said that lying in down will not bring thee to Fame; nor staying beneath the quilts. He who, without Fame, burns his life to waste, leaves no more vestige of himself on earth than wind-blown smoke, or the foam upon the sea. [Footnote: From the last sentence we may infer that this text is by the hand of a pupil of Leonardo’s.– On the same sheet are the notes Nos.1175 and 715 in Leonardo’s own handwriting.]
