the four books *. He must refer
here to a MS. translation, as no Italian translation
is known to have been published (see No. 1477

Try to get Vitolone, which is in the
library at Pavia [Footnote 26: _Vitolone_ see No. 1506, note.

_Libreria di Pavia_. One of the most famous of
Italian libraries. After the victory of Novara in
April 1500, Louis XII had it conveyed to France,
'_come trofeo di vittoria_'!] and which treats of
Mathematics,--He had a master [learned] in
waterworks and get him to explain the repairs
and the costs, and a lock and a canal and
a mill in the Lombard fashion.

A grandson of Gian Angelo's, the painter
has a book on water which was his fathers.

[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.]




Vespuccio will give me a book of Geometry.

Marcantonio Colonna at Santi Apostoli.

[Footnote: In July 1506 Pope Julius II gave Donna
Lucrezia della Rovere, the daughter of his sister
Lucchina, in marriage to the youthful Marcantonio
Colonna, who, like his brothers Prospero and
Fabrizio, became one of the most famous Captains
of his family. He gave to him Frascati
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

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

S.K.M. III. Ia]


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,

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.]

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

a highly valuable and interesting disquisition on this
passage under the title: Leonardo da Vinci e la sua
Libreria, note di un bibliofilo (Milano 1873. Ed. di soli
75 esemplari; privately printed). In the autumn of
1880 the Marchese d'Adda showed me a considerable mass of additional notes prepared for a second
edition. 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*. I did not however think myself justified
in reproducing here the acute and interesting
observations on the contents of most of the rare books
here enumerated.]

****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.

1474. See No. 1421, 1. 3, 6 and Vol. I, No. 343.

1475. Compare No. 1504.

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.

Leonardo says somewhere in MS. C.A.: Archi-

tronito e una macchina di fino rame, invenzlon d* Archi-
mede (see 'Saggiol, p. 20).

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.

whence the noise issued; whether their lower

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 ...

names here mentioned cannot be explained. Leonardo

Messer Vincenzio Aliprando, who lives

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.

[Footnote: In the original, the passage given as No. 1463
is written between lines 2 and 3 of this text, and
it is possible that the entries in lines 3 and 4 refer
to the payments of Jacopo Tedesco, who is there
mentioned. The first words of these lines are very

*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.

On the day of October, 1508, I had
30 scudi; 13 I lent to Salai to make up his

[Footnote: The meaning of this document, which is
very difficult to decipher, and is written in
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.--
