sentences:  Others, while maintaining the attribution of the "Life" to Ignatios, have made an interesting but so far unproven case that the description of the invasion alone was inserted into the "Life" in the second half of the 9th century or later and thus reflects Rus'-Byzantine relations as they stood by that time, after the 860 raid.Others still, including the same Vasiliev in his later production, argued for an even later composition of the "Life" and accordingly held the account of the Paphlagonian raid to echo the 941 attack.This is little more than an unverifiable guess, however, and a rather facile one, given that the work is transmitted by a single 10th-century manuscript.
