Note 28 — Chapter XXII · THE EPIC OF THE CRUSADE.
Reading edition
The poem is written in tirades, or paragraphs of varying lengths, bound together by the same rhyme. At the end of each tirade there is a short line which, in the second portion of the poem, is, as a rule, literally repeated in the first line of the following tirade, while in the first part it only anticipates its rhyme. This difference is the chief metrical evidence against the one-author theory.
