During the roughly 12 centuries of Ancient Roman civilisation, religion developed from a home-grown, pantheistic animism, which was incorporated into the early institutions of the city.
As the Republic and Empire moved forward, Roman religion absorbed the Greek pantheon, included foreign cults and adopted the practice of Emperor worship, before finally embracing Christianity in the final years of the Empire.
Though by some standards deeply religious, Ancient Romans approached spirituality and faith in a different manner to most modern believers. Throughout its history, the concept of numen, an all pervasive divinity or spirituality, pervades Roman religious philosophy.
However, like many pagan faiths, success in life was equated with having a good relationship with the gods. Maintaining this incorporated both mystical prayer and business-like sacrifices in exchange for material benefit.
The Deities of Rome
Roman gods fulfilled different functions corresponding to various aspects of life. There were many gods in Latium, the region in Italy where Rome was founded, some of which were Italic, Etruscan and Sabine.
In Roman belief, immortal gods ruled the heaven, Earth and the underworld.
As Roman territory grew, its pantheon expanded to include the gods and cults of newly conquered and contacted peoples, so long as they fit in with Roman culture. For instance, Roman exposure to Hellenic culture via Greek presence in Italy and later Roman conquest of the city-states of Macedonia and Greece caused the Romans to adopt many Greek myths as well as combine Greek deities with its own corresponding gods.
The Major Gods of Ancient Roman Religion
Gods and goddesses were grouped in various ways. The Di Selecti were considered the 20 main gods, while the Di Consentes comprised the 12 principal deities at the heart of the Roman Pantheon. Though taken from the Greeks, the grouping of 12 gods has pre Hellenic origins, probably in the religions of Lycian and Hittite, both Anatolian peoples.
The gilt statues of the 12 adorned Rome’s central forum. The 6 gods and 6 goddesses were sometimes arranged in male-female couples: Jupiter-Juno, Neptune-Minerva, Mars-Venus, Apollo-Diana, Vulcan-Vesta and Mercury-Ceres.
