:::I'm at work right now (slow day, free to edit Wikipedia) so I don't have a chance to check a specific reference in Keene, but if I recall the first chapter of his Seeds in the Heart is devoted to the Kojiki, and specifies that (1)it is a historical chronicle, (2)it contains infrequent quotations from the poetry of the past and (3)these poems were not composed specifically for the Kojiki. I will provide a more solid reference when I get the chance. Chamberlain's translation, however, is in the public domain and is easily accessible online . The very first verse passage included in the work is in chapter 19, after more than 18 sections of pure Chinese prose. This clearly contradicts Brogan's definition of what constitutes a prosimetrum, which indicates either that (1)his use of the phrase "prosimetric form" in reference to the Kojiki was meant to be distinguished from true prosimetra or (2)he is not particular knowledgeable of the contents of the Kojiki to begin with. The fact is that I have been attempting to reject the use of tertiary sources like the Princeton Encyclopedia and Pauly throughout this discussion, but if we are going to use them we should be using them carefully. Reliable secondary and primary sources written by specialists that seem to contradict the examples cited in tertiary sources. This actually reminds me of another occasion a while back, where the Lafcadio Hearn article cited a list of "transferred nationalists" in a book by George Orwell to justify the inclusion of such a statement in the article, but the fact is that Orwell, who misspelled Hearn's name, was clearly not a reliable source on the subject of Lafcadio Hearn. The fact is that you and Bagworm have consistently ignored the contention, in both Hugh of Bologne and Braund, that a prosimetrum is a "branch of poetic composition"  if there were no poems composed as part of a work, it is not a prosimetrum. Even if we reject the stricter definition of "alternating passages" (I haven't seen any reason why we should, though), our list of examples simply should not include works that blatantly contradict the most basic definition which, as Braund points out, is the only universally accepted one. Including the Kojiki in this list is one step away from inviting casual Wikipedia readers to visit the Kojiki article and add to the opening sentence The Kojiki is a prosimetrum composed in 8th century Japan...(!)
