WHENCE IT IS THAT ONE BIRTH GIVES TWO OR THREE CHILDREN.
EMPEDOCLES affirms, that the superabundance of sperm
and the division of it causes the bringing forth 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 prolific.
Erasistratus, that superfetation may happen to women as
to irrational creatures; for, if the womb be well purged
and very clean, then there may be divers births. The
Stoics, 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.
