Terra was a goddess of the earth.
Although Tellus and Terra are hardly distinguishable during the Imperial era, Tellus was the name of the original earth goddess in the religious practices of the Roman Republic and earlier.
She is regularly associated with Ceres in rituals pertaining to the earth and agricultural fertility. Her attributes were the cornucopia, or bunches of flowers or fruit. She was typically depicted reclining, or rising, waist high, from a hole in the ground. Her male complement was a sky god such as Caelus or a form of Jupiter.
