Chapter X.

Whence it is that One Birth Gives Two or Three Children.

Empedocles affirms, that the superabundance of sperm¹ and the division of it causes the bringing forth² of two or three infants. Asclepiades, that it is performed from the excellent quality of the sperm, after the manner that from the root of one barleycorn two or three stalks do grow; sperm that is of this quality is the most prolific³. Erasistratus, that superfetation may happen to women as to irrational⁴ creatures; for, if the womb be well purged⁵ and very clean, then there can be divers⁶ births. The Stoics⁷, that it ariseth from the various receptacles that are in the womb: when the seed illapses into the first and second of them at once, then there are conceptions upon conception; and so two or three infants are born.
