THE SCENE: Herodotus is an influential figure in the development of the study of history. His forays into natural sciences, however, are less likely to provoke admiration amongst latter-day biologists.
THE TEXT: Somehow the forethought of God (just as is reasonable) being wise has made all creatures prolific that are timid and edible, so that they do not become extinct through being eaten, whereas few young are born to hardy and vexatious creatures. On the one hand, because the hare is hunted by every beast and bird and man, therefore it is quite prolific; alone of all creatures it conceives during pregnancy; some of the unborn young are hairy, some still naked, some are still forming in the womb while others are just conceived. On the one hand there is this sort of thing, but on the other hand the lioness, that is so powerful and so bold, once in her life bears one cub; for in the act of bearing she casts her uterus out with her cub. The explanation of this is that when the cub first begins to stir in the mother, its claws, much sharper than those of any other creature, tear the uterus, and the more it grows the more it scratches and tears, so that when the hour of birth is near seldom is any of the uterus left intact.
So too if the vipers and the winged serpents of Arabia were born in the natural manner of serpents life would be impossible for men; but as it is, when they copulate, while the male is in the act of procreation and as soon as he has ejaculated his seed, the female seizes him by the neck, and does not let go until she has bitten through. The male dies in the way described, but the female suffers in return for the male the following punishment: avenging their father, the young while they are still within the womb gnaw at their mother and eating through her bowels thus make their way out. Other snakes, that do no harm to men, lay eggs and hatch out a vast number of young. The Arabian winged serpents do indeed seem to be numerous; but that is because (although there are vipers in every land) these are all in Arabia and are found nowhere else.
