Roman religious practices were diverse and intricate, spanning public and private spheres. From state-sponsored rituals led by high-ranking priests to household worship of family gods, religion permeated every aspect of Roman life.

Divination played a crucial role in decision-making, with augurs interpreting bird signs and haruspices examining animal entrails. Sacrifices, festivals, and the concept of Pax Deorum (peace with the gods) were central to maintaining divine favor and societal harmony.
