I have memorized most of the first book of Endymion. It has become an extremely enjoyable task, and I want to continue on. I never had memorized much of anything before, so I had to train my memory to make it possible for me to memorize this much poetry. I am interested in knowing about any others who are engaged in learning Keats off by heart.
I had to create a memory index to the Endymion text I have learned so far, so that I can access individual sections without needing to run through all the previous text in order to arrive at the desired section. I generally find that retention is quite good, and I frequently will recall a section or two before I fall asleep. In any situation I am in where I might wish to be elsewhere, i have only to begin reciting some Keats to myself, silently or aloud, to be transported away.
