Why is there no punctuation in the poem Limbo by Edward Kamau Brathwaite?

it is supposed to be symbolic to the slaves' continiuous suffering. Also fits in with the dance that is being acted out with the poem. Because the poem symbolises the journey of the slaves. The poem begins with a capital letter to symbolise the beginning of the journey and ends with a full stop to show the journey has ended. It is a way of using structure and form to reflect or shape meaning. becasue it shows the way the slaves are getting on the boat it shows the flow of the slaves
