I can help you with a summary of "On First Looking into Chapman's Homer," by Keats.  I don't know if it will be "full" or not, since I'm not sure what that is. 

The speaker has traveled widely through classical lands (metaphorically).  In other words, he has read much classical literature.  He has read that Homer is king of the classical writers (the best).  But he never knew this for himself until he read Chapman's translation.

This discovery, for the speaker, was like an astronomer's discovery of a new celestial body, or like a discoverer's discovery of a new ocean.
