Keats(1795-1621);
On first looking Into Chapman's Homer
Much have I fravell'd in the realms of gold, And manly tzoodly states and kingdoms seen;
Round many western islands have I been Which bards in fealty to Apollo hold
Oft of one wide expanse had I been told That deep-brow'd Homer ruled as him demesne:

'Fill I heard Chapman speak out loud and bold
Then felt I like some watcher of the skies When a new planet swims into his ken;
Or like stout cortex.when with eagle eyes
He starld at the pacific -and all his men
Looked at each other with a wild surmise -
