Library Eusebius of Caesarea Preparation for the Gospel
Book 5, Chapter 30
'A medical and not a prophetical answer given to the Athenians when troubled by the burning heat.
"Grandson of Presbon, son of Clymenus,
Thyself, Erginus, would'st the race prolong:
'Tis late; yet give the old plough a new tip."
'For a young woman to be wedded to an old man, if he desires children, this is the advice not of a prophet, but of one who understands nature. Desire, however, sets the weaklings beside themselves.'
