The Rite of Investiture.  
Another ritualistic symbolism, of still more importance and interest, is the rite of investiture.
 
The rite of investiture, called, in the colloquially technical language of the order, the ceremony of clothing, brings us at once to the consideration of that well-known symbol of Freemasonry, the LAMB-SKIN APRON.
 
This rite of investiture, or the placing upon the aspirant some garment, as an indication of his appropriate preparation for the ceremonies in which he was about to engage, prevailed in all the ancient initiations. A few of them only it will be requisite to consider.
 
Thus in the Levitical economy of the Israelites the priests always wore the abnet, or linen apron, or girdle, as a part of the investiture of the priesthood. This, with the other garments, was to be worn, as the text expresses it, "for glory and for beauty," or, as it has been explained by a learned commentator, "as emblematical of that holiness and purity which ever characterize the divine nature, and the worship which is worthy of him."
 
In the Persian Mysteries of Mithras, the candidate, having first received light, was invested with a girdle, a crown or mitre, a purple tunic, and, lastly, a white apron.
 
In the initiations practised in Hindostan, in the ceremony of investiture was substituted the sash, or sacred zennaar, consisting of a cord, composed of nine threads twisted into a knot at the end, and hanging from the left shoulder to the right hip. This was, perhaps, the type of the masonic scarf, which is, or ought to be, always worn in the same position.
 
The Jewish sect of the Essenes, who approached nearer than any other secret institution of antiquity to Freemasonry in their organization, always invested their novices with a white robe.
 
And, lastly, in the Scandinavian rites, where the military genius of the people had introduced a warlike species of initiation, instead of the apron we find the candidate receiving a white shield, which was, however, always presented with the accompaniment of some symbolic instruction, not very dissimilar to that which is connected with the masonic apron.
 
In all these modes of investiture, no matter what was the material or the form, the symbolic signification intended to be conveyed was that of purity.
 
And hence, in Freemasonry, the same symbolism is communicated by the apron, which, because it is the first gift which the aspirant receives,—the first symbol in which he is instructed,—has been called the "badge of a mason." And most appropriately has it been so called; for, whatever may be the future advancement of the candidate in the "Royal Art," into whatever deeper arcana his devotion to the mystic institution or his thirst for knowledge may carry him, with the apron—his first investiture—he never parts. Changing, perhaps, its form and its decorations, and conveying at each step some new and beautiful allusion, its substance is still there, and it continues to claim the honorable title by which it was first made known to him on the night of his initiation.
 
The apron derives its significance, as the symbol of purity, from two sources—from its color and from its material. In each of these points of view it is, then, to be considered, before its symbolism can be properly appreciated.
 
And, first, the color of the apron must be an unspotted white. This color has, in all ages, been esteemed an emblem of innocence and purity. It was with reference to this symbolism that a portion of the vestments of the Jewish priesthood was directed to be made white. And hence Aaron was commanded, when he entered into the holy of holies to make an expiation for the sins of the people, to appear clothed in white linen, with his linen apron, or girdle, about his loins. It is worthy of remark that the Hebrew word LABAN, which signifies to make white, denotes also to purify; and hence we find, throughout the Scriptures, many allusions to that color as an emblem of purity. "Though thy sins be as scarlet," says Isaiah, "they shall be white as snow;" and Jeremiah, in describing the once innocent condition of Zion, says, "Her Nazarites were purer than snow; they were whiter than milk."
 
In the Apocalypse a white stone was the reward promised by the Spirit to those who overcame; and in the same mystical book the apostle is instructed to say, that fine linen, clean and white, is the righteousness of the saints.
