TRUTH. It was not always taught publicly by the ancient philosophers to the people. The search for it is the object of Freemasonry. It is never found on earth, but a substitute for it is provided. TUAPHOLL. A term used by the Druids to designate an unhallowed circumambulation around the sacred cairn, or altar, the movement being against the sun, that is, from west to east by the north, the cairn being on the left hand of the circumambulator. TUBAL CAIN. Of the various etymologies of this name, only one is given in the text; but most of the others in some way identify him with Vulcan. Wellsford (_Mithridates Minor_ p. 4) gives a singular etymology, deriving the name of the Hebrew patriarch from the definite article ה converted into ת, or _T_ and _Baal_, "Lord," with the Arabic _kayn_, "a blacksmith," so that the word would then signify "the lord of the blacksmiths." Masonic writers have, however, generally adopted the more usual derivation of _Cain_, from a word signifying _possession_; and Oliver descants on Tubal Cain as a symbol of worldly possessions. As to the identity of Vulcan with Tubal Cain, we may learn something from the definition of the offices of the former, as given by Diodorus Siculus: "Vulcan was the first founder of works in iron, brass, gold, silver, and all fusible metals; and he taught the uses to which fire can be applied in the arts." See Genesis: "Tubal Cain, an instructor of every artificer in brass and iron." TWENTY-FOUR INCH GAUGE. A two-foot rule. One of the working-tools of an Entered Apprentice, and a symbol of time well employed. TYPHON. The brother and slayer of Osiris in the Egyptian mythology. As Osiris was a type or symbol of the sun, Typhon was the symbol of winter, when the vigor, heat, and, as it were, life of the sun are destroyed, and of darkness as opposed to light. TYRE. A city of Phoenicia, the residence of King Hiram, the friend and ally of Solomon, whom he supplied with men and materials for the construction of the temple. TYRIAN FREEMASONS. These were the members of the Society of Dionysiac Artificers, who at the time of the building of Solomon's temple flourished at Tyre. Many of them were sent to Jerusalem by Hiram, King of Tyre, to assist King Solomon in the construction of his temple. There, uniting with the Jews, who had only a knowledge of the speculative principles of Freemasonry, which had been transmitted to them from Noah, through the patriarchs, the Tyrian Freemasons organized that combined system of Operative and Speculative Masonry which continued for many centuries, until the beginning of the eighteenth, to characterize the institution. See _Dionysiac Artificers_. U UNION. The union of the operative with the speculative element of Freemasonry took place at the building of King Solomon's temple.
