Interpetatio Graeca et Romana

Interpretatio Graeca et Romana is interpreation according to understanding of Greek and Roman culture.
Pliny the Elder expressed the "translatability" of deities as "different names to different peoples" (nomina alia aliis gentibus).[3] This capacity made possible the religious syncretism of the Hellenistic era and the pre-Christian Roman Empire.
Interpretatio romana is comparative discourse in reference to ancient Roman religion and myth, as in the formation of a distinctive Gallo-Roman religion. Both the Romans and the Gauls reinterpreted Gallic religious traditions in relation to Roman models, particularly Imperial cult.
Interpretatio Graeca (Latin, "Greek translation" or "interpretation by means of Greek [models]") is a discourse[1] in which ancient Greek religious concepts and practices, deities, and myths are used to interpret or attempt to understand the mythology and religion of other cultures. It is thus a comparativemethodology that looks for equivalencies and shared characteristics. The phrase may describe Greek efforts to explain others' beliefs and myths, as when Herodotus describes Egyptian religion in terms of perceived Greek analogues, or when Dionysius of Halicarnassus and Plutarch document Roman cults, temples, and practices under the names of equivalent Greek deities. Interpretatio graeca may also describe non-Greeks' interpretation of their own belief systems by comparison or assimilation with Greek models, as when Romans adapt Greek myths and iconography under the names of their own gods.
