Because one line of Robert Browning is never enough.........

From "Pippa Passes"

Day!
Faster and more fast,
O'er night's brim, day boils at last:
Boils, pure gold, o'er the cloud-cup's brim
Where spurting and suppressed it lay,
For not a froth-flake touched the rim
Of yonder gap in the solid grey
Of the eastern cloud, an hour away;
But forth one wavelet, then another, curled,
Till the whole sunrise, not to be suppressed,
Rose, reddened, and its seething breast
Flickered in bounds, grew gold, then overflowed the world.
