On First Looking into Chapman's Homer
1 Much have I travelled in the realms of gold,
  And many goodly states and kingdoms seen;
  Round many western Islands have I been
Which bards in fealty to Apollo hold.
5 Oft of one wide expanse had I been told
  That deep-browed Homer ruled as his demesne;
  Yet never did I breathe its pure serene
Till I heard Chapman speak out loud and bold:
Then felt I like some watcher of the skies
10   When a new planet swims into his ken;
Or like stout Cortez when with eagle eyes
  He stared at the Pacific - and all his men
Looked at each other with a wild surmise
  Silent, upon a peak in Darien.

 

 

 

 

 

 

 

 

 

 

 

 

Annotations
Chapman was a translator of Homer who wrote about the time of Shakespeare; Keats was therefore reading a book already 200 years old. Top
Homer If you've really had to look this up, there's no hope for you. Homer was the father of Western Literature and wrote to epic poems in Greek about 3,000 years ago. Keats was, of course, hugely influenced by ancient Greece. Top
travelled Obviously he doesn't mean it literally. He's been reading - an activity I recommend to you all. Top
western islands Sadly not the "Western Isles" of Scotland, but the islands of the Western Mediterranean. Homer set the Odyssey in what was, to him, completely unknown territory around North Africa and Italy Top
Fealty to Apollo This is your cue - If I said that "bards" is another word for "poets" and 'fealty' means that Apollo was their landlord, you have to find out who Apollo was and why he might be a poet's landlord. Top
demesne means Homer's bit of territory - he ruled there with Apollo as his landlord. This is, of course, a metaphor. Top
Cortez was a Spaniard who led his troops across Central America. He was not the first European to see the Pacific Ocean, which adds to Keats's point - he is not the first person to discover Homer's poetry. Top
