The description agrees with the so-called Abgar picture of Jesus; it also agrees with the portrait of Jesus Christ drawn by Nicephorus, St. John Damascene, and the Book of Painters (of Mt. Athos).
He also compiled a historical work, "Chronographia tripartita", from the Greek writings of Theophanes, Nicephorus, and George Syncellus, and made a collection of documents concerning the affairs of Pope Honorius I.
In 1904 he published a "romantic monograph" of the 10th century Byzantine resurgence, Theophano, and in 1906 a verse tragedy, Nicephorus.
In patristic Greek, the word Stoichiometria was used by Nicephorus to refer to the number of line counts of the canonical New Testament and some of the Apocrypha.
