“ Sometimes, while the people stood around the altar, the rite of circumambulation was performed by the priest alone, who, turning towards the right hand, went around it, and sprinkled it with meal and holy water. In making this circumambulation, it was considered absolutely necessary that the right side should always be next to the altar, and consequently, that the procession should move from the east to the south, then to the west, next to the north, and afterwards to the east again. ”

“ Thus Plautus makes Palinurus, a character in his comedy of "Curculio," say, "If you would do reverence to the gods, you must turn to the right hand." Gronovius, in commenting on this passage of Plautus, says, "In worshipping and praying to the gods they were accustomed to turn to the right hand." ”
