Analogous are those cases spoken of by Bidel of lumbricoides found in the uterus; by Hole, in which maggots were found in the vagina and uterus; and Simpson, in which the abortion was caused by worms in the womb--if the associate symptoms were trustworthy.
We can find fabulous parallels to all of these in some of the older writings.

Pare mentions Lycosthenes' account of a woman in Cracovia in 1494 who bore a dead child which had attached to its back a live serpent, which had gnawed it to death.

He gives an illustration showing the serpent in situ.

He also quotes the case of a woman who conceived by a mariner, and who, after nine months, was delivered by a midwife of a shapeless mass, followed by an animal with a long neck, blazing eyes, and clawed feet.

Ballantyne says that in the writings of Hippocrates there is in the work on "Diseases", which is not usually regarded as genuine, a some what curious statement with regard to worms in the fetus.
