That darksome cave they enter, where they find

That cursed man, low sitting on the ground,

Musing full sadly in his sullein mind.

Edmund Spenser (1553-1599): Faerie Queene. Book i. Canto ix. St. 35.

When, musing on companions gone,

We doubly feel ourselves alone.

Sir Walter Scott (1771-1832): Marmion. Introduction to Canto ii.

The mountains look on Marathon,

And Marathon looks on the sea;

And musing there an hour alone,

I dreamed that Greece might still be free.

Lord Byron 1788-1824: Don Juan. Canto iii. Stanza 86. 3.
