So, when a raging fever burns,

We shift from side to side by turns;

And 't is a poor relief we gain

To change the place, but keep the pain.

Isaac Watts (1674-1748): Hymns and Spiritual Songs. Book ii. Hymn 146.

Thus times do shift,—each thing his turn does hold;

New things succeed, as former things grow old.

Robert Herrick (1591-1674): Ceremonies for Candlemas Eve.
