o
Western cience
By Martin Bernalt
SPENT
THE FIRST FIFTY YEARS
of
my
life trying to escape
from
the
shadow
of
my father,
John
Desmond
Bernal,
and
hence, among
other things,
from science
and the
history
of science.
Therefore,
the
trepidation
hat
is
proper
for
anyone
who is neithera scientist nor
a
historian
of science
writing
for Isis
is
multipliedmanyfold n my case. Nevertheless, I am grateful or the invitationto
put
forward my
views on the
origins
of
Western science.
Any approach
to
this
question immediately
stumbles over
the
definition
of
"science."
As no ancient
society possessed
the modern
concept
of
"science" or
a
word for
it, its application
to
Mesopotamia,
Egypt,
China,
India,
or Greece is
bound
to be
an
arbitrary
mposition.
This lack
of
clarity
is exacerbatedby the
clash
between
historians,
ike David
Pingree,
who are concerned
with
"sciences"
as
"functioningsystems
of
thought"
within
a
particular
society
and
those
who
apply
transhistorical
tandards
and see "science"
as "the
orderly
and
systematic
comprehension,
description
and/or
explanation
of natural
phenomena
. . .
[and]
the tools necessary for the undertaking ncluding, especially, mathematics and
logic."'
I
should
add the words
"real or
imagined"
after "natural
phenomena."
Pingree
denounces
the
claims
of what he calls
"Hellenophilia"
hat "science"
is
an
exclusively
Greek
invention
owing
little or
nothing
to earlier civilizations
and
that it was
passed
on
without
interference
o the
Western
European
makers
of the "scientific
revolution."
Puzzlingly,
the work
of Otto
Neugebauer-and
his
school,
including Pingree
himself-on
the extent
and
sophistication
of
Mesopo-
tamian
astronomy
and
mathematics
and
Greek
indebtedness to
it,
as well as
M. L. West's
demonstration
of the Near
Eastern influences on the
Presocratic
cosmologies, appearsto have left this kind of thinkingunscathed.2

CULTURES
OF ANCIENT
SCIENCE
597
There are
still defenders
of
the
claim
that
"Thales [seen as
a Greek]was the
first
philosopher
scientist"-the
word "scientist"
beingused here
in the positivist
sense.
According
to G. E. R. Lloyd,
the Greeks
were the
first
to "discoverna-
ture,"
"practice
debate," and
introduce
such specifics
as the study of
irrational
numbers(notably
V2)
and geometrical
modelingfor astronomy.
Lloyd sees the
discovery of
nature as
"the
appreciation
of the
distinctionbetween 'natural'and
'supernatural,'
hat is the recognition
that natural
phenomena
are not
the prod-
ucts
of random
or arbitrarynfluences
but regular
and governed
by determinable
sequences
of cause
and
effect.
3 However,
it is clear that
at least by
the second
millenniumB.C.
Mesopotamian
astronomy and
Egyptian
medicine,
to take two
examples,
were concerned
with
regular
and,
if
possible,
predictable
phenomena
with
relativelylittle supernatural
nvolvement.4
It is true that Egyptian
medicine
contained
some
religion
and magic.
At one
point even the "scientific"Edwin Smith Papyruson surgeryturns to magical
charms.
However,
E.
R.
Dodds
and
others have
shown
how
isolated
the natural
philosophers'
criticism
was
against
the
widespread
Greek belief
in the
efficacy
of
magic.S
Even
Hippocratic
medicine,
which is
generally
regarded
as
highly
ratio-
nal,
was institutionally
centered
on
the
religious
cult
of Asclepius and
his ser-
pents,
which
laid
great
emphasis
on the
religious
practice
of incubation.
Both
the
cult
and
the
practice,
incidentally,
had clear
Egyptian
roots.6
On
the question
of the
alleged uniqueness
of
Greek "scientific"debate, as
we
can
see
from those
in
Gilgamesh,
"debates"
are
at least as old as literature.
Some, such as the "Disputebetween a man and his Ba," which dates back to
Middle
KingdomEgypt,
contain
quite
profound
philosophy.
It is also clear
that
different
Mesopotamian, Syrian,
and Egyptian
cities
had not
merely
different
gods
but
distinct
cosmogonies,
most
of which involved abstract elements
or
forces
without
cults,
of
which
the
priesthoods
of the others
were aware.
There
were also attempted
and
actual
syncretizations,
suggesting
that
there had
been
debates.7
This situation
resembles
that
plausibly
reconstructed
or the
cosmolog-
ical disputes
of the Presocratics.
Later Greek
philosophical
and scientific
debates
clearly
owed a
great
deal
to
the
Sophists,
who came
from the
Greek tradition
of
"persuasion,"

BERNAL:
ANIMADVERSIONS
association
with
legal
disputes.Oratory,persuasion,
and
ustice arehighly valued
in nearly
all cultures, but, interestingly,
they received particular
emphasis in
Egypt. The central
scene
in
Egyptian conography
s the
judicialweighing of the
soul of
the dead
person,
and
the
legal
battle between
Horus and Seth is a central
episode in its mythology.Oneof the mostpopularEgyptian exts was that of The
EloquentPeasant,
which its most recent translator
nto English, MiriamLicht-
heim,
describes as "both
a serious disquisitionon the
need for
justice and a
parableon
the utility of fine speech."8
I
have
written
elsewhere
on the
centrality
of
the
image
of
Egyptian
ustice
to
both Mycenaean
and Iron
Age
Greece,
and
there
is
no doubt that
Greeks
of
the
Classical
and Hellenistic
periods
saw
Egyptian
aw
as the ultimatebasis of
their
own.
As
Aristotle wrote at
the end of the Politics: "The
history
of
Egypt
attests
the antiquity
of all political
institutions.
The
Egyptiansare generally
accounted
the oldest people on earth;andthey have alwayshad a body of law anda system
of
politics.
We
ought
to take
over
and use what has
already
been
adequately
expressed
before us and
confine
ourselves
to
attempting
to discover what has
already
been omitted."9
While
the first attestation
of
written law
in
Egypt
comes from the tomb
of
Rekhmire
n
the fifteenth
centuryB.C.,
there
is no reason to doubt that it existed
much earlier.10
n
any
event,
the
Egyptian
New
Kingdom
is
sufficiently
old by
Greek standards.
It is
clear
that what
Aristotle
was
recommending
had not
hith-
erto been
carriedout. Nevertheless,
it would
seem
likely
that Aristotle was
con-
ventional in his belief that, even thoughEgyptianand Greek law were very dif-
ferent
in
his own
day,
the true foundationof Greek
law and
justice
lay
in
Egypt.
The
emphasis
on
law
is
important
both because
of its
promotion
of
argument
and
dialectic and
because
of the
projections
of social law into nature and the
establishment
of
regularities.'1
There
is no doubt
that the
Egyptian
M3t
(Maat:
"truth,""accuracy,"
"justice")
was
central to
both
social
and natural
spheres
in
the same way as
the Greek Moira,
which
derivedfrom
it.
Similarly,
t is
clear
that
the Egyptians applied
the
"justice"
of
scales
to social and
legal
life at least as
early
as
the Middle
Kingdom.12
To
return to some
of the
specific
claims made
for the
originality
of Greek
science, there is now no doubt that Babylonianscholars were concerned with
2
and
Pythagorean riples
as
well
as
having
a
good approximation
of 'a. The
Egyptian
estimate
for wr
was
even
more accurate.

a
square

cubit

the
so-called double

that is to say
\/2
times
the
cubit.

Thus the irrational
number
par
excellence
was
employed
in
Egyptfromthe beginning
of
the
second millenniumB.C. at the
latest;
whether or not its irrationalitywas proved
in
Euclidean
fashion, its use provides
circumstantial vidence that Egyptianscribeswere aware of the incommensura-
bility of the side and
the
diagonal.
Modern scholars
have
poured scorn on
the
widespread
ancient
tradition
hold-
ing that Egyptians had known of
the
"Pythagorean" riangle. However, the very
cautious
Gay
Robins
and
Charles
Shute have
accepted
Beatrice
Lumpkin'sargu-
ment that knowledge of
it
is shown
by
the
use
in
Late
Old
Kingdompyramidsof
a
seked of 54 palms,
which
imposed
"a
half-base width to
height
of 3:4 and
so
could
have been modelled on
a
3:4:5
right angled triangle."14
I
shall discuss
the
strong
possibility
that
geometry, thought
to be
typically
Greek, came fromEgypt. However, at this point it would seem difficult o argue
that before the second half of
the
fourth
centuryB.C. any aspect
of
Greek "sci-
ence"
-with the
possible exception
of
axiomatic mathematics-was
more ad-
vanced
than
that of
Mesopotamia
or
Egypt.
WAS
NEUGEBAUER
RIGHT
TO
DISMISS ANCIENT
TRADITIONS OF
EGYPTIAN
SCIENCE?

I
should
like
to take
it
as
given
that R. 0.
Steuer, J.
B. de

Saunders,

Ghalioungui
have established not
merely
that
Egyptianmed-

Greekmedicine,but thatEgyptianmedicineplayeda centralrole in the develop-
ment of Greek medicine.
15
Similarly,
he work of
Neugebauer
and
his school has
made
it
impossible to deny that some Mesopotamianmathematicians nd astron-
omers
were "scientific"
n
the
positivist
sense and that
Mesopotamian
"science"
in
these areas was
crucial to the
creation
of Greek
mathematics
and
astronomy.
However,
I
should
like to
challenge
these scholars' dismissal of claims that there
was an
Egyptian
mathematics that could
have had
a
significant influence on
Greek thinkers.

BERNAL:
ANIMADVERSIONS
Despite his early passionfor
ancient
Egypt
and
his
considerablework on Egyp-
tian astronomy, throughout
his
long
life
Neugebauer
insisted that
the
Egyptians
had no original or
abstract ideas
and
that
mathematically
and
scientificallythey
were not on the same
level
as
the
Mesopotamians.
He claimed that the
accurate
astronomicalalignments
of the
pyramids
and
temples
in
Egypt
and
the
use of
ir
and
4
could
all be
explained
as
the
results of
practical
knacks
rather
than
of
profound thought.
An
example
of
this
approach
is
the
following:
"It
has
even
been claimed that
the
area
of
a hemispherewas correctly
found in an
exampleof
the Moscow papyrus, but
the text
admits also
of
a
much more
primitive nterpre-
tation which
is
preferable."
16
In
his Exact Sciences in AntiquityNeugebauer
did not
argue
with the
pyrami-
dological school;
he
simply
denounced
it, recommending
hat
those interested
in
what
he
admitted o be
"the
very complex historical
and
archaeologicalproblems
connected with the pyramids"read the books by I. E. S. Edwards and J. F.
Lauer
on the
subject.
17
While
Edwards does not involve himself with
the
pyramidologists
and their
calculations, the surveyor
and
archaeologist
Lauer
did,
in the
face of
opposition
from Egyptologists, who
were
"astonished
that
we
shouldgive so much impor-
tance to
the
discussion of theories
which have never had
any
credit in the
Egyp-
tologicalworld." Lauer's
work had a certain
contradictoryquality.
He
admitted
that
the
measurementsexhibitedby
the
pyramids
do have
some remarkableprop-
erties;
that one can
find
such relations as
ir, +,
and
Pythagoras's triangle from
them; and that these facts generallybear out the claims Herodotus and other
ancient writers made for
them.
On
the
other
hand,
he
denounced the
"fantasies"
of
pyramidologists
and claimed that the
formulas
according
to which
the
pyra-
mids
were
aligned
and the
extraordinarydegree
of
sidereal
accuracy they
exhib-
ited were
purely
the
result
of
"intuitiveand utilitarian
mpiricism."18
A
conflict between
the
acceptance
of the
extraordinary
mathematical
precision
of the
Great
Pyramid
and
a
"certainty"
that
the Greeks
were
the
first "true"
mathematicians unsthroughout
Lauer's
many writings
on the
subject.The strain
is
made
still
harder o bear
by Lauer's awareness
that
some
Greeks
had been
told
about many
of this
pyramid's extraordinary
eatures and that
they
believed the
Egyptians
to
have been the
first mathematicians
and
astronomers. Moreover,
there
was
the
problem
that
so many
of the Greek
mathematicians
and
astrono-
mers
had studied
in
Egypt.
Lauer's
honest
attempt
to deal with
these difficulties
was
the
following:
Even
though up
to
now,
no
esoteric
Egyptian
mathematicaldocument has been dis-
covered,
we
know,
if we can
believe
the
Greeks,
that the
Egyptianpriests
were
very
jealous
of the secrets of their science and
that
they occupied themselves,
Aristotle
tells
us,
in
mathematics.
It
seems then
reasonably probable
that
they
had
been
in
possession of an esoteric science erected, littleby little, in the secrecy of the temples
during
he
long
centuries that
separate
the
constructionof the
pyramids,

601
year 2800 [I shouldput
it two hundred
years earlier],
to the eve of
Greek mathemat-
ical
thought
n
the sixth
century
B.C.
As far as
geometry
s
concerned,
the
analysis of
buildings
as famous as the Great
Pyramid
would take
a notable
place
in
the
researches
of these priests; and
it is
perfectly
conceivable that
they could
have
succeeded in
discovering
n
it, perhaps ong
after their
erection,
chance
qualities hat hadremained
totally unsuspected
to the constructors.19
The
question
of
when
Egyptians developed
this
sophisticated mathematical
knowledge is not directly
relevant to the
topic
of this article.
However, apart
from
the
precision
and
intricacy
of
many
of
the architectural
constructions
of
the
Old
Kingdom,
there is another
argument
for
the
existence of
relatively
"ad-
vanced" mathematics
in
the first half of
the third millennium B.C.
This is that
although the
two
great
mathematical
texts
that have
survived,
the
Moscow and
the Rhind papyri, come from
the
Middle Kingdom
in the
twentieth and nineteenth
centuries
B.C.,
some of the problems set in them use measures that belong to the
Old
Kingdom,
which had
been
discarded
by
this time.20
Lauer's solution still
allowed some
later
Egyptians
to
have been
capable of
relatively advanced thought. He continued:
For the whole
length
of
the three
thousand
years
of
her
history, Egypt thus,
little
by
little, prepared
he
way
for the Greek scholars
who
like
Thales, Pythagoras,
and
Plato
came
to
study,
then even
to
teach,
like Euclid at the school
in
Alexandria.But it
was
in
theirphilosophicspirit,which
knew how to draw from the treasureamassed
by the
technicalpositivism
of the
Egyptians,
that
geometry
came
to
the
stage
of a
genuine
21
science.
Even this
degree
of
recognition
was too
much for
Neugebauer.
As
he
put
it
at
one
point:
"Ancient science was
the
product
of
a
very
few men and
these
few
happened
not to be
Egyptians."
In
1981 he
published
his
note "On the
Orienta-
tion of Pyramids,"
in
which
he
showed how
accurate
alignments
could be
made
without
sophisticated astronomy, simply by measuring
and
turning
the shadow
of
a
model
pyramid
or
the
capstone
over
a
period
of some weeks. There
is no
evidence,
one
way
or
the
other,
whether
this
was the method
used,
but it
would
seem
plausible,
if
only
because
pyramids appear
to
have
had
solar
rather than
stellar
cultic
associations.
Nevertheless,
the
requirement
of what
Neugebauer
concedes
to be "remarkable
accuracy
of
.
..
orientation of
the
Great
Pyramid,"
a
structure
of
extraordinary sophistication,
indicates
very
serious
religious
and
theoretical
concerns.22
Thus, Neugebauer's
choice of the word
"primitive"
to
describe
the
alignment
seems
inappropriate;
the word
is-as
we
shall see-indic-
ative of his
general opinion
of
the ancient
Egyptians.
There
is
little doubt that this modern
view of the
Egyptians'
lack
of
mathemat-
ics and science has
been influenced
by
a
distaste
for the
theology
and
metaphys-
ics
in
which
much
of
Egyptian-and Platonic-knowledge
was embedded
and
by
progressivist views that no one who lived so early could have been so sophisti-

cated.
It
may also
have
been reinforced
by assumptions,
almost universal
in
the
nineteenth and early
twentieth
centuries,
that
no Africans
of any sort could have
been capable of such great
intellectual achievements.
An indication
that
such
attitudes
may
have had an
impact
even
on such a
magnificentchampion of
liberalism and foe to racism
as Neugebauer comes in
one
of
his bibliographicalnotes,
where
the
first
book
he
recommended
"for
a
deeper understanding
of the
background
hat
determined
he
characterof
Egyp-
tian arithmetic" was Lucien
Levy-Bruhl's Fonctions mentales dans les societes
inferieures.Levy-Bruhl
was far
from the
worst
of his
generation.Nevertheless
he
belonged
to
it,
and it
was appropriate
hat his work was translated nto English as
How Natives
Think.23
Having said this,
there is no doubt
that
Neugebauer
had
some substantialar-
guments
to back his case.
The
strongest
of these
were
his claims
that
none of the
survivingmathematicalpapyrifrompharaonicEgyptcontained what he believed
to be sophisticated
calculations
and that
the
Egyptians'systems
of
numbersand
fractions were too crude
for profound
mathematicaland
astronomical hought of
the kind that had been
attributed
to
them. There are
seven
major arguments
against this position.
1. The strong possibility
that-pace Neugebauer-the survivingEgyptianpapyri do
contain "advanced"
mathematics.
2. Parallels rom Mesopotamia
and PtolemaicEgyptshowing that one cannot rely on
the papyrological
record
to
gauge
the full
range
of
pharaonic
Egyptian
"science."
3. The general agreement hat Egyptiangeometrywas equal to or better than that of
Mesopotamia, in conjunction
with the conventional wisdom that one
of
the chief
contributions
of the Greeks
to
Mesopotamian
"arithmetic"was
geometric modeling,
which suggests
that the
geometrical nput may
well
have come from Egypt.
4. The coordinationof
sophisticated geometry
and
computation
n
Egypt
with
ex-
traordinarypractical
achievements.
5.
The Greek insistence that
they
learned
mathematics-and medicine-not
from
Mesopotamia
but
from
Egypt.
6. The Greek
adoption
of an
Egyptian
rather han a
Mesopotamian
alendar.
7. The facts that much
of Hellenistic and Roman
science
took
place
in
Egypt,
not
Greece,
and that
although hey
wrote in Greek some of
its
practitioners, ncluding
he
astronomerPtolemy, were Egyptian.
The
first
argument
s buttressed
by
the
fact
that,
as
we have
seen, Neugebauer
preferred
"more
primitive
interpretations"
nd therefore could have
overlooked
evidence of
more
sophisticated
work. Thus
we
must
allow
for the
possibility
that
the
surviving
texts
contain or
refer to
elements
that are
more
sophisticated
than
he and
some
other twentieth-century
historians
of science have
supposed.
There
is little doubt about
the
employment
of
irrational
numbers,
mentioned
above,
and
the use of
arithmeticaland
geometricalprogressions
n the
Rhind
Papyrus prob-
lems 40
and

The Soviet scholar
V. V.
Struve,
who
was the
first to
study
the
Moscow Math-
ematical
Papyrus,
was much more
respectful
than
Neugebauer.
He
wrote,
for
instance,
that "we

edge than we wanted to
believe."
He
was convinced that
this
papyrus and
the
Rhind Mathematical Papyrus
demonstrated
a theoretical
knowledge
of the
vol-
ume of a truncated pyramid,
and he
has
been followed
in
this
interpretation by
later scholars. Given the many pyramids successfully constructed during the Old
and Middle Kingdoms,
this
would not
in
itself
seem
unlikely. Archimedes,
how-
ever, maintained
in the third
century
B.C. that the volumes of
pyramids
were
first
measured by Eudoxos of Knidos
a hundred
years
earlier.25
Here, as
in
some
other
instances,
Archimedes
was
knowingly
or
unknowingly
mistaken.
Even
so,
it
is possible
that Eudoxos
was the first
to transmit the
for-
mulas
to Greece. Eudoxos
spent many years
in
Egypt
and
was
reported
to
have
learned Egyptian
and
to
have made
translations,
some
of which may
well have
come from
the
Book of the Dead,
into Greek. As
Giorgio
de
Santillana
pointed
out,
it is
unlikely
that Eudoxos
translated
these texts
merely
for their entertain-
ment value; it is much more probable that he believed that they contained eso-
teric astronomical information.26 This raises
the
important suggestion that Egyp-
tian
religious
and
mystical writings
and
drawings may
well
contain
esoteric
mathematical
and
astronomical
wisdom.
To
return
to
earth with
the
particular
case
of the measurement of
the
surface
area of either
a
semicylinder
or
a
hemisphere
in
the
Moscow
Papyrus:
Richard
Gillings,
who
believes the measurement
refers
to
the
latter, describes
the
Egyp-
tian
operations
and writes:
If this interpretation.. is the correctone, then the scribe who derived the formula
anticipated
Archimedes
by 1,500 years
Let
us, however,
be
perfectly
clear
[that]
in
neither case has
any proof
that either
Acylinder
=
1-rTdhr
Ahemisphere
=
27Tr2been
2
established
by
the
Egyptian
scribe
that is at all
comparable
with
the
clarity
of
the
demonstrations
f the Greeks Dinostratosand
Archimedes.
All we can
say
is
that,
in
the
specific
case
in
hand,
the mechanical
operations performed
are
consistent
with
these
operations
which would be made
by
someone
applying
these
formulas even
though
the order and
notation
might
be different.27
In
general,
it
is clear
that the
specifically mathematical papyri give consider-
able indications of sophisticated operations. As Struve put it in the conclusion of
his study
of the Moscow
Papyrus:
These
new facts
through
which the Edwin Smith and Moscow
papyri
have
enriched
our
knowledge, oblige
us to make
a radical
revision of
the
evaluationmade
up
to now
of
Egyptian
"science"
[Wissenschaft].
Problems such as the research
into
the
func-
tions
of
the brainor the surfacearea of a
sphere
do
not
belong
to the
range
of
practical
"scientific"
questions
of a
primitive
culture.
They
are
purely
theoretical
problems.

BERNAL: ANIMADVERSIONS
Or
earlier:
The Moscow Papyrus ... confirms
n
a strikingway
the mathematicalknowledge of
the Egyptian scholars and
we no
longer
have
any reason
to reject the claims of the
Greek writers that the Egyptianswere the teachersof the Greeksin geometry.28
Objectionsby Neugebauer
and others
to
Struve's
specificinterpretation f
the
surface
area of
a
hemisphere
have now been answered.29
Similarly,as mentioned
above, claimsfor the use of "Pythagorean"riangles
and the
sophisticationof the
measurementof
the
volume of
the
truncated
pyramid
have both survived earlier
skepticism.
If these bases of
Struve's
general
case still
stand,
should one
accept
Neugebauer's
dismissal of
it?
Even if one were to concede Neugebauer's argumentthat the mathematics
containedin these papyriis merely practicaland primitive,there is the second
argument:
he
strong
likelihood
that more
sophisticated
work
was recorded on
others that
have
not
been
preserved.
Lauer raised
the
point
that
all
reports
indi-
cate
that the
Egyptianpriests
were
secretive about
their
writings;thereforethere
would have
been few
copies
and
the
chances of
their
survival would have been
slim.
It should
be
emphasized
that
relatively
few
papyri
of any
kind
have sur-
vived. This is very
different rom
Mesopotamia,
where the
baked clay tablets are
remarkablydurable and hundreds of thousands
of them have been
discovered.
The problem
with
Mesopotamian
exts is not
a
lack
of them but the
difficultyof
finding enough Assyriologists
to read and
publish
them.
Even
here, however,
there are gaps in what exists. Neugebauerpoints out that the "greatmajority"of
mathematical
tablets come from one of
two
periods,
the
Old
Babylonian pe-
riod-of
two hundred
years-in
the
first
half
of
the second millennium
B.C. and
the Seleucid period. Continuities
between
the two
sets
of texts
make
it
clear that
sophisticated
mathematicswas
carried out
in the
twelve or more centuries that
intervened. However,
there
is
no record of this.30
The
situation
is far
worse
in
Egypt,
and there
is
no
doubt
that
most of the
papyri
written and all
of those
that have survived
were texts
used for
teaching
scribes
techniques
that
were useful for
practical
accounting
ratherthan "state
of
the art" advanced
mathematics.31
An instructiveparallelcan be seen in the Ptole-
maic
period. Many
more
mathematical
papyri
have been found
from
these
few
centuries
than from the whole
pharaonic period, yet
none of these
go beyond
book
1
of Euclid
or
give any
indicationsof
the
extraordinary ophistication
of the
work
we know from textual transmission
o have been
takingplace
in
Hellenistic
Egypt.
Thus
the
argument
from
silence,
which should
always
be
applied spar-
ingly,
should
be
used
with
particular
aution
in
evaluating
he
absence of textual
proof
of advanced
Egyptian
mathematics.
Against this,
it is
argued
that the few texts that do exist show
a
consistency
of
techniquesand notationthat makes it impossiblefor the Egyptiansto have pro-
duced
sophisticated
mathematics. This
brings
us to
the third
argumentagainst
skepticism:Egyptian
numericalnotation
may
not have been as flexible and

ful
as
that
of
the
Mesopotamians,
but it
was,
if
anything,
better than that in
which
the
Greeks wrote their
sophisticated formulas. There is no doubt
that Egyptian
mathematicswas
based on
very simple
principles;
on the other
hand,
the
existing
papyri show
that
extraordinarily
laborate mathematical
tructureswere
erected
upon them.
Neugebauer
admits that while the
Egyptians
were
not as
good
in
their
arithme-
tic as the Babylonians,
their
geometry
was
equally good;
and if we
are to
believe
other scholars' interpretationsof the Moscow
Papyrus, Egyptians were able
to
carry
out
geometricaloperations
that were
beyond
those
of the
Mesopotamians.
The
notion
that the
Egyptians
were
the
better
geometers
fits both with
their
unparalleledarchitectural achievements
and with
their
reputation
among
the
Greeks
as
the founders of
geometry
and their
teachers
in
it.32
Given
this
concern
with
geometry,
it
is
not
surprising
that there
are
many
direct and indirectproofs that Egyptiansrelied on plans for their architectural
constructions.
Struve
may
have been
exaggerating
when he
wrote,
"The
Egyp-
tian
plans are as correct as those
of
modern
engineers."33Nevertheless, there is
no
reason to suppose
that
they were inferior o those of
the
Greeks and
Romans.
According
to
the
Egyptians,
the
tradition
of
makingplans
went
back to
Imho-
tep, at the beginning of
the
third
dynasty, circa 3000 B.C., but
most modern
scholars
have
understood this claim
merely
as
a
mythical
projection
onto the
deified
prototype
of
all
architects.
However,
it
is now
proven
that
architectural
plans were used
during
the Old
Kingdom
and that
Imhotep
did
design
the
Step
Pyramidand the elaboratecomplex of buildingsaroundit. Furthermore,an os-
tracon
found
at
the
Step Pyramid
does contain measurements or a vault.34
This
coordination
of
geometry
and
computation
with
architecture
constitutes
the fourth
argumentagainst
modern
denials that
the
Egyptianspossessed a supe-
rior mathematics.
While
the textual evidence for
such
knowledge
can be con-
strued
as
ambiguous,
the
case
for it is
greatly strengthenedby
the
architectural
evidence.
In
addition to the
pyramids
there were
temples,
granaries,
and
irriga-
tion networks
on
huge scales
that
required
extraordinary lanning
and the
ability
to visualize
these
structures
n
advance on
writing
or
drawing
surfaces.
The
fifth
reason
for
supposing
that the

BERNAL: ANIMADVERSIONS
ever, as
de Santillanawrote about
Eudoxos,
who
undoubtedlystudied in Egypt:
"We
are asked
to
admit, then,
that the
greatest
mathematician f
Greece learned
Egyptian and tried to work on astronomy
n
Egypt without realizingthat he was
wasting his time."35
There is little doubt that after the Persianconquests the mathematicsand as-
tronomy of Egypt
drew from both
Egyptian
and
Mesopotamiansources. How-
ever, the Greek belief that it was an Egyptiantraditionstrengthens he case that
the native component was significant.
The
sixth argumentagainst
the
skeptics
is the fact that the
Greeksadoptedan
Egyptian rather than a Mesopotamiancalendar.
Apart
from the
greater conve-
nience of the Egyptiancalendar,this adoption s indicativeof what seems to have
been
a
wider Greek tendency to drawfromnearbyEgyptrather hanmore distant
Mesopotamia.
The final argument is that in Hellenistic times, while Athens remainedthe
center of
Greek
philosophicalstudies, nearly
all "Greek"
science took place in
Egypt. This was partly the result of Ptolemaic
patronage,
but if
we are to believe
Greek
and Roman
sources, they
also drew and built on
Egyptian
wisdom. It is
striking
that
Euclid worked
in
Egypt
at the
very beginning
of the
Ptolemaic
period,
that
is
to
say
a mere
fifty years
after Eudoxos had felt
the need to learn
Egyptian
in
order to study mathematics and
astronomy. Thus,
it
would seem
more
accurate to
view
Euclid's work as
a
synthesis
of
Greek and
Egyptian ge-
ometry
than as an
imposition
of the Greek rational mind
on muddled oriental
thinking.
While it is true that Babylonianmathematicsand astronomyflourishedunder
the
Seleucids,
as
already noted,
most
of
the
great
"Greek"
scientists
wrote
in
Greek
but
lived in
Egypt,
and some indeed
may
have been
Egyptian.
For exam-
ple,
the astronomer
Ptolemy
was known
in
early
Arabic
writings
as DAc
acid,
"the
Upper Egyptian.
36
It
seems to
be
generally accepted
that the
great
Greek
contribution
o mathe-
matics
and
astronomy
was the introductionof
geometric modeling,
in
particular
the
transposition
of
Mesopotamian
arithmetical
astronomical
cycles
into
rotating
spheres.37However,
the Greeks themselves believed that
geometry developed
in
Egypt, a view supportedby Egyptianarchitectural ophisticationand the math-
ematical
papyri. Furthermore,
hose most
responsible
for the Greek view
of the
heavens
as
spinning spheres,
Plato and
Eudoxos,
were
reported
to have
spent
time in
Egypt
and were known for
their
deep
admiration
of
Egyptian
wisdom.38
We
have seen how
particularly
close
Eudoxos's
association
was with
Egyptian
priests,
and
it
was
precisely
Eudoxos who
established the new
astronomy
of
complex
concentric
spheres.
I
believe that these seven
arguments
present
a
very strong
case indeed that
there
were
rich
mathematical-particularlygeometrical-and
astronomical radi-
tions in Egypt by the time Greek scholars came in contact with Egyptian earned
priests.

the
first Persian
conquest
of
Egypt,

CULTURES
OF
ANCIENT
SCIENCE
607
tian mathematics
and
astronomy
were
substantially nfluencedby
Mesopotamian
"scientific"
hought,
a
process
which
continued
n
Ptolemaicand Roman
Egypt.39
The Egyptianmedical tradition
appears
to have been less
affected
by
Mesopota-
mia.
In
general,
the
"scientific"
riumphs
of
Hellenistic
Egypt
would
seem to be
the result of
propitioussocial,
economic,
and
politicalconditions
and
the
meeting
of three "scientific"
raditions,
those
of
Egypt,
Mesopotamia,
and
Greece. How-
ever, the two former
were
much older than
the
third,
reaching
back to the
third
millennium
or
beyond,
and more
substantial.
It
should also be noted
that the
point
at
which
the
Greeks
"plugged
nto" Near Eastern "science"
was
Egypt;
this
was the reason
that the
Greeks
always emphasized
he
depth
and extent
of
Egyp-
tian wisdom.
The arbitrarinessof the
applicationof the word "science" to ancient
civiliza-
tions was noted
at
the
beginningof this essay.
I
suppose,
like
Humpty-Dumpty,
we can use wordsmore or less as we please. However, the only way to claimthat
the
Greeks
were
the first Western scientists is to define
"science" as
"Greek
science."
If
less circular definitions are
used,
it is
impossible
to
exclude the
practice
and
theory
of
some
much earlier
Mesopotamians
and
Egyptians.
