The Rite of Circumambulation.  
The rite of circumambulation will supply us with another ritualistic symbol, in which we may again trace the identity of the origin of Freemasonry with that of the religious and mystical ceremonies of the ancients.
 
"Circumambulation" is the name given by sacred archaeologists to that religious rite in the ancient initiations which consisted in a formal procession around the altar, or other holy and consecrated object.
 
The prevalence of this rite among the ancients appears to have been universal, and it originally (as I shall have occasion to show) alluded to the apparent course of the sun in the firmament, which is from east to west by the way of the south.
 
In ancient Greece, when the priests were engaged in the rites of sacrifice, they and the people always walked three times around the altar while chanting a sacred hymn or ode. 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. It was in this way that the apparent revolution was represented.
 
This ceremony the Greeks called moving ε? δεξια εν δεξια, from the right to the right, which was the direction of the motion, and the Romans applied to it the term dextrovorsum, or dextrorsum, which signifies the same thing. 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."
 
A hymn of Callimachus has been preserved, which is said to have been chanted by the priests of Apollo at Delos, while performing this ceremony of circumambulation, the substance of which is, "We imitate the example of the sun, and follow his benevolent course."
 
It will be observed that this circumambulation around the altar was accompanied by the singing or chanting of a sacred ode. Of the three parts of the ode, the strophe, the antistrophe, and the epode, each was to be sung at a particular part of the procession. The analogy between this chanting of an ode by the ancients and the recitation of a passage of Scripture in the masonic circumambulation, will be at once apparent.
 
Among the Romans, the ceremony of circumambulation was always used in the rites of sacrifice, of expiation or purification. Thus Virgil describes Corynasus as purifying his companions, at the funeral of Misenus, by passing three times around them while aspersing them with the lustral waters; and to do so conveniently, it was necessary that he should have moved with his right hand towards them.
 
"Idem ter socios pura circumtulit unda,
Spargens rore levi et ramo felicis oliv?."
?n. vi. 229.
 
"Thrice with pure water compassed he the crew,
Sprinkling, with olive branch, the gentle dew."
 
In fact, so common was it to unite the ceremony of circumambulation with that of expiation or purification, or, in other words, to make a circuitous procession, in performing the latter rite, that the term lustrare,............
