Book III chapter 8

Thus, as regards digestion¹, even though he neglected everything else, he did at least attempt to prove his point — namely, that digestion in animals differs from boiling carried on outside; in regard to the question of deglutition, however, he did not go even so far as this. What are his words?

“The stomach does not appear to exercise any traction².”

Now the fact is that the stomach possesses two coats, which certainly exist for some purpose; they extend as far as the mouth, the internal one remaining throughout similar to what it is in the stomach, and the other one tending to become of a more fleshy nature in the gullet. Now simple observation will testify that these coats16 have their fibres inserted in contrary directions. And, although Erasistratus did not attempt to say for what reason they are like this, I am going to do so.

The inner coat has its fibres straight, since it exists for the purpose of traction. The outer coat has its fibres transverse, for the purpose of peristalsis. In fact, the movements of each of the mobile organs of the body depend on the setting of the fibres. Now please test this assertion first in the muscles themselves; in these the fibres are most distinct, and their movements visible owing to their vigour³. And after the muscles, pass to the physical organs, and you will see that they all move in correspondence with their fibres. This is why the fibres throughout the intestines⁵ are circular in both coats — they only contract peristaltically, they do not exercise traction. The stomach, again, has some of its fibres longitudinal for the purpose of traction and the others transverse for the purpose of peristalsis. For just as the movements in the muscles take place when each of the fibres becomes tightened⁷ and drawn⁸ towards its origin, such also is what happens in the stomach; when the transverse fibres tighten⁶, the breadth of the cavity contained by them becomes less; and when the longitudinal fibres contract and draw in upon themselves, the length must necessarily be curtailed¹⁰. This curtailment¹¹ of length, indeed, is well seen in the act of swallowing: the larynx is seen to rise upwards¹² to exactly the same degree that the gullet is drawn downwards¹³; while, after the process of swallowing has been completed and the gullet is released from tension, the larynx can be clearly seen to again. This is because the inner coat of the stomach, which has the longitudinal fibres and which also lines the gullet and the mouth, extends to the interior of the larynx, and it is thus impossible for it to be drawn down by the stomach without the larynx being involved in the traction.

Further, it will be found acknowledged in Erasistratus’s own writings that the circular fibres (by which the stomach as well as other parts performs its contractions) do not curtail⁹ its length, but contract and lessen¹⁵ its breadth. For he says that the stomach contracts peristaltically round the food during the whole period of digestion. But if it contracts, without in any way being diminished in length, this is because downward traction of the gullet is not a property of the movement of circular peristalsis. For what alone happens, as Erasistratus himself said, is that when the upper parts contract the lower ones dilate¹⁶. And everyone knows that this can be plainly seen happening even in a dead man, if water be poured down his throat; this symptom results from the passage of matter through a narrow channel; it would be extraordinary if the channel did not dilate when a mass was passing through it. Obviously then the dilatation of the lower parts along with the contraction¹⁴ of the upper is common both to dead bodies, when anything whatsoever¹⁷ is passing through them, and to living ones, whether they contract peristaltically round their contents or attract them.

Curtailment of length, on the other hand, is peculiar¹⁸ to organs which possess longitudinal fibres for the purpose of attraction. But the gullet was shown to be pulled down; for otherwise it would not have drawn upon the larynx. It is therefore clear that the stomach attracts food by the gullet.

Further, in vomiting²⁰, the mere²¹ passive conveyance²² of rejected matter up to the mouth will certainly itself suffice to keep open those parts of the oesophagus which are distended²³ by the returned food; as it occupies each part in front [above], it first dilates²⁴ this, and of course leaves the part behind [below] contracted. Thus, in this respect at least, the condition of the gullet is precisely²⁵ similar to what it is in the act of swallowing. But there being no traction, the whole length remains²⁶ equal in such cases.

And for this reason it is easier to swallow than to vomit¹⁹, for deglutition results the coats of the stomach being brought into action, the inner one exerting a pull and the outer one helping²⁷ by peristalsis and propulsion, whereas emesis occurs from the outer coat alone functioning, without there being any kind of pull towards the mouth. For, although the swallowing of food is ordinarily preceded by a feeling of desire on the part of the stomach, there is in the case of vomiting no corresponding desire from the mouth-parts for the experience; the two are opposite dispositions²⁸ of the stomach itself; it yearns²⁹ after and tends towards what is advantageous³⁰ and proper to it, it loathes³¹ and rids itself of what is foreign. Thus the actual process of swallowing occurs very quickly in those who have a good appetite for such foods as are proper to the stomach; this organ obviously draws them in and down before they are masticated³²; whereas in the case of those who are forced to take a medicinal draught³³ or who take food as medicine, the swallowing of these articles is accomplished³⁴ with distress³⁵ and difficulty.

From what has been said, then, it is clear that the inner coat of the stomach (that containing longitudinal fibres) exists for the purpose of exerting a pull the from to stomach, and that it is only in deglutition that it is active, whereas the external coat, which contains transverse fibres, has been so constituted in order that it may contract upon its contents and propel them forward; this coat furthermore, functions in vomiting no less than in swallowing. The truth of my statement is also borne out by what happens in the channae and synodonts;17 the stomachs of these animals are sometimes found in their mouths, as also Aristotle writes in his “History of Animals”; he also adds the cause of this: he says that it is owing to their voracity³⁶.

The facts are as follows. In all animals, when the appetite is very intense, the stomach rises up, so that some people who have a clear perception of this condition say that their stomach “creeps out” of them; in others, who are still masticating³⁷ their food and have not yet worked it up properly in the mouth, the stomach obviously snatches away the food from them against their will. In those animals, therefore, which are naturally voracious³⁸, in whom the mouth cavity is of generous proportions, and the stomach situated³⁹ close to it (as in the case of the synodont and channae), it is in no way surprising that, when they are sufficiently⁴⁰ hungry and are pursuing one of the smaller animals, and are just on the point of catching⁴¹ it, the stomach should, under the impulse of desire, spring into the mouth. And this cannot possibly take place in any other way than by the stomach drawing the food to itself by means of the gullet, as though by a hand. In fact, just as we ourselves, in our eagerness to grasp more quickly something lying before us, sometimes stretch out our whole bodies along with our hands, so also the stomach stretches itself forward along with the gullet, which is, as it were, its hand. And thus, in these animals in whom those three factors co-exist — an excessive propensity⁴² for food, a small gullet, and ample mouth proportions — in these, any slight tendency to movement forwards brings the whole stomach into the mouth.

Now the constitution of the organs might itself suffice to give a naturalist⁴³ an indication of their functions. For Nature would never have purposelessly constructed the oesophagus of two coats with contrary dispositions; they must also have each been meant to have a different action. The Erasistratean school, however, are capable of anything rather than of recognizing the effects of Nature. Come, therefore, let us demonstrate to them by animal dissection⁴⁴ as well that each of the two coats does exercise the activity which I have stated. Take an animal, then; lay bare the structures surrounding the gullet, without severing⁴⁵ any of the nerves, arteries⁴⁶, or veins⁴⁷ which are there situated; next divide with vertical⁴⁸ incisions⁴⁹, from the lower jaw⁵⁰ to the thorax, the outer coat of the oesophagus (that containing transverse fibres); then give the animal food and you will see that it still swallows although the peristaltic function has been abolished. If, again, in another animal, you cut through both coats with transverse incisions, you will observe that this animal also swallows although the inner coat is no longer functioning. From this it is clear that the animal can also swallow by either of the two coats, although not so well as by both. For the following also, in addition to other points, may be distinctly observed in the dissection which I have described — that during deglutition the gullet becomes slightly filled with air which is swallowed along with the food, and that, when the outer coat is contracting, this air is easily forced with the food into the stomach, but that, when there only exists an inner coat, the air impedes⁵¹ the conveyance of food, by distending⁵² this coat and hindering its action.

But Erasistratus said nothing about this, nor did he point out that the oblique⁵³ situation of the gullet clearly confutes the teaching of those who hold that it is simply by virtue⁵⁴ of the impulse from above that food which is swallowed reaches the stomach. The only correct thing he said was that many of the longnecked animals bend down to swallow. Hence, clearly, the observed fact does not show how we swallow but how we do not swallow. For from this observation it is clear that swallowing is not due merely to the impulse from above; it is yet, however, not clear whether it results from the food being attracted by the stomach, or conducted by the gullet. For our part, however, having enumerated⁵⁵ all the different considerations — those based on the constitution of the organs, as well as those based on the other symptoms which, as just mentioned, occur both before and after the gullet has been exposed — we have thus sufficiently proved that the inner coast exists for the purpose of attraction and the outer for the purpose of propulsion.

Now the original task we set before ourselves was to demonstrate that the retentive⁵⁶ faculty⁵⁷ exists in every one of the organs, just as in the previous book we proved the existence of the attractive, and, over and above this, the alterative⁵⁸ faculty. Thus, in the natural course of our argument, we have demonstrated these four faculties⁵⁹ existing in the stomach — the attractive faculty in connection with swallowing, the retentive with digestion, the expulsive with vomiting and with the descent of digested food into the small intestine⁴ — and digestion itself we have shown to be a process of alteration⁶⁰.
