held the generative parts within and fashioned the conceived thing female. For the right cavity of the uterus from above receives the beginning of the seed from the vena cava, while the left receives the seed coming down from the kidneys. Because of this, the nature flowing down from the vena cava is without superfluity and boiling with heat, while that entering the left uterus from the kidneys is less hot, but more superfluous. The kidneys are at an equal distance; but the right one is higher and is irrigated first from the vena cava, while the left is a little lower; and venous cavities extend directly into each, from which the blood filtered from the vena cava descends into the testicles and there, changing its color from its blood-like quality, it exchanges it for the color and power of seed. 4. Concerning Seed The account of Ctesias and Herodotus is false; for the one, as if telling a myth, says that the seed of elephants solidifies and becomes like amber; while the other declares that the Ethiopians emit black seed. For the substance of seed, as it seems to Aristotle, is neither purely watery nor precisely of blood. For if it were water, it would not solidify when heated, but it comes out thick and foamy; but if it secreted pure blood, it would have to solidify upon being external and cooled. For neither is water solidified by heat, and blood thickens when cooled; but seed, being heated within, comes out thicker, and when it is outside, it dissolves into thin water. It is possible, then, to conjecture that it is composed of two things, I mean of water and pneuma, just as oil mixed with water, when it is agitated, becomes foamy; it is a residue of the second digestion, I mean of the blood; and being produced in the ligament it changes the color of blood to a whiter one. And it is not a waste product of the whole body; for this would be against nature, and from what is against nature a most rational animal could not come into being. But being moved by the gadfly of venereal desire and being checked in many ways, it is filled with pneuma and becomes foamier; but the bubbles in it do not rise up very much, for the thick part overpowers the pneuma. But Aristotle says that females do not produce seed, but emit a certain thin moisture, which becomes matter for the seed of the male; for otherwise, he says, either two animals would be produced, or one composite from both. But this opinion is not pleasing to those around Hippocrates; for Galen says that females also emit seed. 5. For what reason do acts of intercourse seem more pleasurable to those who dream You wonder with good reason that venereal acts exceed the measure of pleasure for those who are dreaming more than for those who are awake. For from this Aristides the rhetor compared real delights to the former rather than the latter. And the reason for these things being so is this. There is in us a certain twofold life, the one free from the body, the other constituted with the body, and the one is irrational, the other rational. Therefore, in waking {intercourse}, the rational life does not completely release the reins of pleasure to the irrational, but just as the irrational part of desire, being arrayed under reason as its leader, is not completely self-willed with regard to venereal impulses, but being gently drawn back by the bridle of reason, it has its pleasure curtailed through the contrary desire. But in sleep, when this rational life, separate from the body, is active in itself, the horse of desire, having, as it were, thrown off its rider, reason, and having become far from fear and trembling, is wholly given over to that fantastical desire and motion. Whence, for those who dream in this way, when reason rises up against it, the pleasures suddenly and unexpectedly become incomplete. Hence, for the more temperate, their offspring are often harmed and more imperfect in both their bodily temperament and their practical
