Lecturile, instruirea și experiențele patriarhului Photios al Constantinopolului au fost modelate și distilate în cele 256 de pastile de înțelepciune conservate în acest gnomologium. Astfel, cele 252 de aforisme și patru chreiae au, în primul rând, o dimensiune practică. Sfaturile lui Photios și feluritele circumstanțe descrise sunt preluate din imediatul cotidian. Ele au scopul de a-l învăța pe om cum să se comporte în această lume, asupra căreia Photios insistă păstrând, totuși, conștiința că nu este, de fapt, din această lume. Omul resimte permanent tensiunea a două stări contrastante, căci el trăiește între aici-și-acum al acestei existențe terestre și nu-încă al Împărăției Cerești.
Photios I (/ˈfoʊʃəs/; Greek: Φώτιος, Phōtios; c. 810 – c. 893a[›]), also spelled Photius or Fotios, was the Ecumenical Patriarch of Constantinople from 858 to 867 and from 877 to 886. He is recognized in the Eastern Orthodox churches as St. Photios the Great.
Photios is widely regarded as the most powerful and influential Patriarch of Constantinople since John Chrysostom, and as the most important intellectual of his time, "the leading light of the ninth-century renaissance". He was a central figure in both the conversion of the Slavs to Christianity and the Photian schism.
Photios was a well-educated man from a noble Constantinopolitan family. Photius's great uncle was the previous Patriarch of Constantinople, Tarasius. He intended to be a monk, but chose to be a scholar and statesman instead. In 858, Emperor Michael III (r. 842–867) deposed Patriarch Ignatius of Constantinople, and Photios, still a layman, was appointed in his place. Amid power struggles between the pope and the Byzantine emperor, Ignatius was reinstated. Photios resumed the position when Ignatius died (877), by order of the Byzantine emperor. The new pope, John VIII, approved Photios's reinstatement. Catholics regard a Fourth Council of Constantinople (Roman Catholic) as anathematizing Photios as legitimate. Eastern Orthodox regard a second council named the Fourth Council of Constantinople (Eastern Orthodox), reversing the first, as legitimate. The contested Ecumenical Councils mark the end of unity represented by the first seven Ecumenical Councils.
