The Sonnet Poem by Richard Watson Gilder

What is a sonnet? 'Tis the pearly shell
That murmurs of the far-off murmuring sea;
A precious jewel carved most curiously:
It is a little picture painted well.
What is a sonnet? 'Tis the tear that fell
From a great poet's hidden ecstasy;
A two-edged sword, a star, a song-ah me!
Sometimes a heavy-tolling funeral bell.
This was the flame that shook with Dante's breath;
The solemn organ whereon Milton played,
And the clear glass where Shakespeare's shadow falls:
A sea this is-beware who ventureth!
For like a fjord the narrow floor is laid
Mid-ocean deep to the sheer mountain walls.
