The so-called mother of the child isn't the child's begetter, but only a sort of nursing soil for the new-sown seed. The man, the one on top, is the true parent, while she, a stranger, foster's a stranger's sprout.
Chorus: Zeus, who guided men to think who laid it down that wisdom comes alone through suffering. Still there drips in sleep against the heart grief of memory; against our pleasure we are temperate.
