"But sometimes by a cruel necessity, whilst yet in the womb, an infant is put to death, when lying awry in the orifice of the womb he impedes parturition, and kills his mother, if he is not to die himself. Accordingly, among surgeons’ tools there is a certain instrument, which is formed with a nicely-adjusted flexible frame for opening the uterus first of all, and keeping it open; it is further furnished with an annular blade,1676 by means of which the limbs within the womb are dissected with anxious but unfaltering care; its last appendage being a blunted or covered hook, wherewith the entire fœtus is extracted by a violent delivery. There is also (another instrument in the shape of) a copper needle or spike, by which the actual death is managed in this furtive robbery of life: they give it, from its infanticide function, the name of ἐμβρυοσφάκτης, the slayer of the infant, which was of course alive."
