In the “Lapidaire” of Philippe de Valois, it is said that “the books tell us the beautiful clear and fine ruby is the lord of stones; it is the gem of gems, and surpasses all other precious stones in virtue.” In the time of Marbodus (end of the eleventh century A.D.) the same proud place was assigned to the sapphire. The ruby is spoken of in similar terms in the “Lapidaire en Vers,” where it is called “the most precious of the twelve stones God created when He created all creatures”. By Christ’s command the ruby was placed on Aaron’s neck, “the ruby, called the lord of gems; the highly prized, the dearly loved ruby, so fair with its gay color.”[144] As with diamonds, rubies also were divided by the Hindus into four castes. The true Oriental ruby was a Brahmin; the rubicelle, a Kshatriya; the spinel, a Vaisya, and lastly, the balas-ruby, a Sudra. The possession of a _padmarâga_, or Brahmin ruby, conferred perfect safety upon the owner, and as long as he owned this precious stone he could dwell without fear in the midst of enemies and was shielded from adverse fortune. However, great care had to be taken to preserve this ruby of the first class from contact with inferior specimens, as its virtue would thereby be contaminated, and its power for good correspondingly diminished.[145] The many talismanic virtues of the ruby are noted in the fourteenth century treatise attributed to Sir John Mandeville.[146] Here the fortunate owner of a brilliant ruby is assured that he will live in peace and concord with all men, that neither his land nor his rank will be taken from him, and that he will be preserved from all perils. The stone would also guard his house, his fruit-trees, and his vineyards from injury by tempests. All the good effects were most surely secured if the ruby, set in ring, bracelet, or brooch, were worn on the left side. The gorgeous ruby, the favorite gem of Burma, where the finest specimens are found, is not only valued for its beauty, but is also believed to confer invulnerability. To attain this end, however, it is not thought to be sufficient to wear these stones in a ring or other piece of jewelry, but the stone must be inserted in the flesh, and thus become, so to speak, a part of its owner’s body. Those who in this way bear about with them a ruby, confidently believe that they cannot be wounded by spear, sword, or gun.[147] As it is often remarked that the most daring and reckless soldiers pass unscathed through all the perils of war, we can understand that this superstition may sometimes appear to be verified.
