"London, 1802"

Milton! thou shouldst be living at this hour:

England hath need of thee:

she is a fanofstagnant waters:

altar, sword, and pen,Fireside, the heroic wealth of hall and bower,

Have forfeited their ancient English dowerOf inward happiness.

We are selfish men;Oh! raise us up, return to us again;

And give us manners, virtue, freedom, power.

Thy soul was like a Star, and dwelt apart;

Thou hadst a voice whose sound was like the sea:

Pure as the naked heavens, majestic, free,

So didst thou travel on life's common way,

In cheerful godliness; and yet thy heart

The lowliest duties on herself did lay.
