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.
