That Brandan's transcript of the "Cantilena" is faulty is evident from various internal traits. Furthermore, the reasons for which Brandan recalled the work, and even the manner in which he did so, is unto this day a baffling uncertainty. The cheerfulness felt by Brandan apparently seems to be doubly caused, namely by both the memory of the composition "and" the memory of his ancestor (with a necessary relationship of one to the other). Brandan's opening sentence of the short prologue seems to suggest that he was gladdened "more" by the relationship than by any of the related parts. Wettinger and Fsadni had suggested that it was the consolation which Brandan saw in the content of the composition that prompted him to leave us a memory of it, writing it down in one of the registers of his acts. But this is a question which must still be open to discussion.
