Religion played a central role in Roman daily life and customs surrounding death. The Romans believed in many gods like Jupiter, king of the gods, Neptune who ruled the sea, and Pluto who ruled the underworld. They built temples to gods and made daily offerings and sacrifices to ensure gods' favor. Funerals and burial rites were also deeply religious affairs, with coins placed under the deceased's tongue to pay the ferryman Charon, and elaborate rituals to ensure a good afterlife judgment. The Roman pantheon of gods, and religious customs surrounding life and death, reflected how integral religion was to everyday life and society in ancient Rome.
