390 PAPPUS OF ALEXANDRIA<br />
Book V. Preface on the Sagacity <strong>of</strong> Bees.<br />
It is characteristic <strong>of</strong> the great <strong>Greek</strong> mathematicians that,<br />
whenever they were free <strong>from</strong> the restraint <strong>of</strong> the technical<br />
language <strong>of</strong> <strong>mathematics</strong>, as when for instance they had occasion<br />
<strong>to</strong> write a preface, they were able <strong>to</strong> write in language <strong>of</strong><br />
the highest literary quality, comparable with that <strong>of</strong> the<br />
philosophers, his<strong>to</strong>rians, and poets. We have only <strong>to</strong> recall<br />
the introductions <strong>to</strong> Archimedes's treatises and the prefaces<br />
<strong>to</strong> the different Books <strong>of</strong> Apollonius's Conies. Heron, though<br />
severely practical, is no exception when he has any general<br />
explanation, his<strong>to</strong>rical or other, <strong>to</strong> give. We have now <strong>to</strong><br />
note a like case in Pappus, namely the preface <strong>to</strong> Book V <strong>of</strong><br />
the Collection. The edi<strong>to</strong>r, Hultsch, draws attention <strong>to</strong> the<br />
elegance and purity <strong>of</strong> the language and the careful writing<br />
the latter is illustrated <strong>by</strong> the studied avoidance <strong>of</strong> hiatus. 1<br />
The subject is one which a writer <strong>of</strong> taste and imagination<br />
would naturally find attractive, namely the practical intelligence<br />
shown <strong>by</strong> bees in<br />
selecting the hexagonal form for the<br />
cells in the honeycomb. Pappus does not disappoint us ; the<br />
passage is as attractive as the subject, and deserves <strong>to</strong> be<br />
reproduced.<br />
'<br />
It is <strong>of</strong> course <strong>to</strong> men that God has given the best and<br />
most perfect notion <strong>of</strong> wisdom in general and <strong>of</strong> mathematical<br />
science in particular, but a partial share in these things he<br />
allotted <strong>to</strong> some <strong>of</strong> the unreasoning animals as well. To men,<br />
as being endowed with reason, he vouchsafed that they should<br />
do everything in the light <strong>of</strong> reason and demonstration, but <strong>to</strong><br />
the other animals, while denying them reason, he granted<br />
that each <strong>of</strong> them should, <strong>by</strong> virtue <strong>of</strong> a certain natural<br />
instinct, obtain just so much as is needful <strong>to</strong> support life.<br />
This instinct may be observed <strong>to</strong> exist in very many other<br />
species <strong>of</strong> living creatures, but most <strong>of</strong> all in bees. In the first<br />
place their orderliness and their submission <strong>to</strong> the queens who<br />
rule in their state are truly admirable, but much more admirable<br />
still is their emulation, the cleanliness they observe in the<br />
gathering <strong>of</strong> honey, and the forethought and housewifely care<br />
they devote <strong>to</strong> its cus<strong>to</strong>dy. Presumably because they know<br />
themselves <strong>to</strong> be entrusted with the task <strong>of</strong> bringing <strong>from</strong><br />
the gods <strong>to</strong> the accomplished portion <strong>of</strong> mankind a share <strong>of</strong><br />
1<br />
Pappus, vol. iii, p. 1233.<br />
ambrosia in this form, they do not think it proper <strong>to</strong> pour it<br />
carelessly on ground or wood or any other ugly and irregular<br />
material ; but, first collecting the sweets <strong>of</strong> the most beautiful<br />
flowers which grow on the earth, they make <strong>from</strong> them, for<br />
the reception <strong>of</strong> the honey, the vessels which we call honeycombs,<br />
(with cells) all equal, similar and contiguous <strong>to</strong> one<br />
another, and hexagonal in form. And that they have contrived<br />
this <strong>by</strong> virtue <strong>of</strong> a certain geometrical forethought we<br />
may infer in this way. They would necessarily think that<br />
the figures must be such as <strong>to</strong> be contiguous <strong>to</strong> one another,<br />
that is <strong>to</strong> say, <strong>to</strong> have their sides common, in order that no<br />
foreign matter could enter the interstices between them and<br />
so defile the purity <strong>of</strong> their produce. Now only three rectilineal<br />
figures would satisfy the condition, I mean regular<br />
figures which are equilateral and equiangular; for the bees<br />
would have none <strong>of</strong> the figures which are not uniform. . . .<br />
There being then three figures capable <strong>by</strong> themselves <strong>of</strong><br />
exactly filling up the space about the same point, the bees <strong>by</strong><br />
reason <strong>of</strong> their instinctive wisdom chose for the construction<br />
<strong>of</strong> the honeycomb the figure which has the ,most angles,<br />
because they conceived that it would contain more honey than<br />
either <strong>of</strong> the two others.<br />
'<br />
Bees, then, know just this fact which is <strong>of</strong> service <strong>to</strong> themselves,<br />
that the hexagon is greater than the square and the<br />
triangle and will hold more honey for the same expenditure <strong>of</strong><br />
material used in constructing the different figures. We, however,<br />
claiming as we do a greater share in wisdom than bees,<br />
will investigate a problem <strong>of</strong> still wider extent, namely that,<br />
<strong>of</strong> all equilateral and equiangular plane figures having an<br />
equal perimeter, that which has the greater number <strong>of</strong> angles<br />
is always greater, and the greatest plane figure <strong>of</strong> all those<br />
which have a perimeter equal <strong>to</strong> that <strong>of</strong> the polygons is the<br />
circle.'<br />
Book V then is devoted <strong>to</strong> what we may call isoperimetry',<br />
including in the term not only the comparison <strong>of</strong><br />
the areas <strong>of</strong><br />
different plane figures with the same perimeter, but that <strong>of</strong> the<br />
contents <strong>of</strong> different solid figures with equal surfaces.<br />
Section (1). lsoperimetry after Zenodorus,<br />
The first section <strong>of</strong> the Book relating <strong>to</strong> plane figures<br />
(chaps. 1-10, pp. 308-34) evidently followed very closely<br />
the exposition <strong>of</strong> Zenodorus wepl la-ouerpcou crxv yLOLTQ&v (see<br />
pp. 207-13, above) ; but before passing <strong>to</strong> solid figures Pappus<br />
inserts the proposition that <strong>of</strong> all circular segments having
