But soon as Time that bears and nurtures all
Wrought out another change in human life,—
Whether some rapt Promethean utterance,
Or strong Necessity, or Nature’s teaching
Through long experience, their deliverance brought,—
Holy Dêmêter’s fruit it gave them; the sweet spring
Of Bacchus they discovered, and the earth,
Unsown before, was ploughed with oxen; cities then
They girt with towers and sheltering houses raised,
And turned their savage life to civil ways;
