ニケフォロス1世
Despite his close ties to Empress Irene of Athens and Nikephoros I, the hagiography is noteworthy for its "lack of anti-Iconoclastic invective". As a result, and because of some similarities in the treatment of Emperor Nikephoros I to Nikephoros II Phokas () Alexander Kazhdan suggested a date of composition towards the end of the 10th century.
