This article will examine the various hermeneutical principles of the hermeneutics of the Patriarch of Constantinople Photius in the context of contemporary Byzantine philosophy. Photius is considered one of the greatest exegetes of the ninth century and has dealt with almost all types of hermeneutics. His works, especially "Αμφιλοχία" contain the most basic hermeneutic principles, which are to be mentioned briefly: The allegorical interpretation used not only by Photius, but also by Origen and the other Fathers of the Orthodox Church, under which one understands that another meaning should be found besides the literal meaning of the text. The typological interpretation that relates to future facts or events, referring to the New Testament, and referred to as "τύπος" or "άντίτυπος". Photius is dependent on the tradition formulated by the Fathers of the Church, and it plays a major role in explaining and shining light on the scriptures for both the Old and the New Testaments. Orthodox Christian extradition, as expressed and drafted in the resolutions of the local and ecumenical synods, certainly has great significance for the hermeneutics of the New Testament. Photius also deals with the darkness of Scripture, and in Quaestion 152 (P. G. Migne 101, 816) gives ten reasons for this, and he tries to redeem these dark points. The ambiguity of Scripture is refuted by several arguments, especially he mentions "to θηριώδες" the listener and the Hebrew language.
