From Homer To Rome And Beyond: A Study Of The Ruler Cults Of The Hellenistic World, Sarah Meade

Williams Honors College, Honors Research Projects

Rulers at the helm of imperial states seem to be surrounded by material culture and protocol (i.e. rituals) to legitimize their position and ensure the continued loyalty of their subjects. An interesting iteration of this phenomenon are the ruler cults of the Hellenistic world, which evolved out of ancient Greek hero worship. When Alexander of Macedon began his conquests, he not only utilized the familiar aspects of the Greek cults, but he also integrated Egyptian and Persian practices in order to establish his ruler cult. Alexander’s influence was then responsible for the ruler cult spiking in popularity during the Hellenistic …
