5. "The extremity of these veins is divided, one branch goes to the thumb, and another to the wrist, and from these many small branches are extended upon each hand, and the fingers; and others, smaller still, branch off from these first veins, from the right side to the liver, from the left to the spleen and kidneys. The veins, which go to the legs, are divided near the junction, and extend through the whole thigh; but the largest of these extends to the back of the thigh, and appears thick; another, less thick, passes through the inside of the thigh, and afterwards veins extend by the knee to the leg and foot. As on the hands, they are distributed upon the tarsus of the foot, and from thence to the toes. 6. "A number of small veins are distributed on the stomach and the lungs. Those that extend to the head, through the jugular region, appear large in the neck. From the extremity of each of these many veins are distributed upon the head, some on the right side to the left, others on the left side to the right, they all end near the ear. And there is a second vein upon the neck on each side, somewhat less than the other, to which the principal veins of the neck are united. These pass inwards, through the neck, and from each of them veins pass beneath the shoulder-blade and to the hands; and near the splenetic and hepatic veins there appear others a little less, which they divide when any disease attacks the skin; but the hepatic and splenetic veins are divided for any disease in the neighbourhood of the stomach. 7. "Other veins pass from these, beneath the breasts; and there are other small ones, which proceed from each of these through the spinal marrow to the testicles, and others beneath the skin, through the flesh, reach the kidneys; in men they terminate upon the testicles, in women on the uterus. The first veins from the stomach are wider, and afterwards become smaller, until they pass over from the right to the left, and from the left to the right; these are called the spermatic veins. The thickest blood is beneath the flesh, but that which is in excess in these places becomes thin, and warm, and frothy." These are the opinions of Syennesis and Diogenes. 8. Polybus[91] writes thus: "There are four pair of veins, one from the back of the head through the neck, on the outside, near the spine on either side, as far as the thighs and the legs, afterwards through the legs to the ancles, on the outside, and to the feet. Wherefore, in complaints of the back and thigh, they divide the veins upon the poplitic region, or ancles, on the outside. Another pair of veins pass from the head, by the ears, through the neck, these are called the jugular veins; and others within, near the spine, lead by the loins to the testicles and the thighs, and through the poplitic region on the inside, and through the leg to the inner part of the ancle, and the feet; wherefore, in complaints of the loins and testicles, they bleed in the poplitic region and ancles.
