Time will run back and fetch the Age of Gold.

The line imagines time itself reversing course to restore a lost “Age of Gold”—the classical myth of an original era of justice, peace, and abundance. In Milton’s usage (where it occurs), the phrase works as a compact emblem of providential hope: history is not merely decline from an ideal past, but can be redeemed or renewed. The striking verb “fetch” makes the Golden Age sound like something recoverable rather than irretrievably gone, suggesting a moral or spiritual restoration that can make the world newly “golden.” The sentiment also resonates with Renaissance and Christian ideas of renewal, in which a fallen present can be transformed by divine or virtuous intervention.
