Chapter XXIII.

What are the Causes of Sleep and Death?

Alcmaeon says, that sleep is caused when the blood retreats to the concourse of the veins¹, but when the blood diffuses² itself then we awake and when there is a total retirement³ of the blood, then men die. Empedocles, that a moderate cooling of the blood causeth sleep, but a total remotion of heat from blood causeth death. Diogenes, that when all the blood is so diffused⁴ as that it fills all the veins, and forces the air contained in them to the back and to the belly⁵ that is below it, the breast being thereby⁶ more heated, thence sleep arises, but if everything that is airy in the breast forsakes⁷ the veins, then death succeeds. Plato and the Stoics⁸, that sleep ariseth from the relaxation⁹ of the sensitive spirit, it not receiving such total relaxing as if it fell to the earth, but so that that spirit is carried about the intestine¹⁰, parts of the eyebrows¹¹, in which the principal part has its residence; but when there is a total relaxing of the sensitive spirit, death ensues.
