Terminalia was an ancient Roman festival in honour of the god Terminus, who presided over boundaries. His statue was merely a stone or post stuck in the ground to distinguish between properties. His worship is said to have been instituted by Numa who ordered that every one should mark the boundaries of his landed property by stones to be consecrated to Jupiter Terminalis, and at which every year sacrifices were to be offered at the festival of the Terminalia. On the festival the two owners of adjacent property crowned the statue with garlands and raised a crude altar, on which they offered up some corn, honeycombs, and wine, and sacrificed a lamb or a suckling pig. They concluded with singing the praises of the god. The public festival in honour of this god was celebrated at the sixth milestone on the road towards Laurentum doubtless because this was originally the extent of the Roman territory in that direction.
