The Byzantine missionaries, Constantine and Methodius, were sent to Khazars and the Great Moravia by the Byzantine court of Michael III. Later, Methodius probably visited the court of Basil I where some of his disciples - who visited the court of his successor, Leo VI the Wise as well - could likely come. The “Solun Brothers” and some of their disciples might have met the emperors in the presence of their family, courtiers, servants and guards in the Chrysotriklinos in the 860s – 880s. The primary sources on the ceremonies of the Byzantine court are De ceremoniis aulae Byzantinae, Kletorologion and Vita Hadriani II and the iconographical sources for the examined period are the Homilies of Gregory of Nazianzus and the Khludov Psalter.
