X/Self by Edward Kamau Brathwaite.

X/Self is a book-length work divided into five parts, which are further divided into individual, closely connected poems. The thematic and stylistic connection among these shorter poems is so strong that the work is best thought of as a single, unified poem. As such, it is also the final third of a larger sequence that Edward Brathwaite began with the publication of Mother Poem (1977), continued in Sun Poem (1982), and concluded in X/Self.
