The Crux Ansata is found on the sculptures of Khorsabad; on the ivories from Nimroud, of the same age, carried by an Assyrian Monarch; and on cylinders of the later Assyrian period.
As the single Tau represents the one God, so, no doubt, the Triple Tau, the origin of which cannot be traced, was meant to represent the Trinity of his attributes, the three Masonic pillars, WISDOM, STRENGTH, and HARMONY.
The Prophet Ezekiel, in the 4th verse of the 9th chapter, says: "And the Lord said unto him, 'Go through the midst of the city, through the midst of Jerusalem, and mark the letter TAU upon the foreheads of those that sigh and mourn for all the abominations that be done in the midst thereof." So the Latin Vulgate, and the probably most ancient copies of the Septuagint translate the passage. This Tau was in the form of the cross of this Degree, and it was the emblem of life and salvation. The Samaritan Tau and the Ethiopic Tavvi are the evident prototype of the Greek [Greek: τ]; and we learn from Tertullian, Origen, and St. Jerome, that the Hebrew Tau was anciently written in the form of a Cross.
In ancient times the mark Tau was set on those who had been acquitted by their judges, as a symbol of innocence. The military commanders placed it on soldiers who escaped unhurt from the field of battle, as a sign of their safety under the Divine Protection.
It was a sacred symbol among the Druids. Divesting a tree of part of its branches, they left it in the shape of a Tau Cross, preserved it carefully, and consecrated it with solemn ceremonies. On the tree they cut deeply the word THAU, by which they meant God. On the right arm of the Cross, they inscribed the word HESULS, on the left BELEN or BELENUS, and on the middle of the trunk THARAMIS. This represented the sacred Triad.
It is certain that the Indians, Egyptians, and Arabians paid veneration to the sign of the Cross, thousands of years before the coming of Christ. Everywhere it was a sacred symbol. The Hindus and the Celtic Druids built many of their Temples in the form of a Cross, as the ruins still remaining clearly show, and particularly the ancient Druidical Temple at Classerniss in the Island of Lewis in Scotland. The Circle is of 12 Stones. On each of the sides, east, west, and south, are three. In the centre was the image of the Deity; and on the north an avenue of twice nineteen stones, and one at the entrance. The Supernal Pagoda at Benares is in the form of a Cross; and the Druidical subterranean grotto at New Grange in Ireland.
The Statue of Osiris at Rome had the same emblem. Isis and Ceres also bore it; and the caverns of initiation were constructed in that shape with a pyramid over the Sacellum.
Crosses were cut in the stones of the Temple of Serapis in Alexandria;
and many Tau Crosses are to be seen in the sculptures of Alabastion and
Esné, in Egypt. On coins, the symbol of the Egyptian God Kneph was a
Cross within a Circle.
The Crux Ansata was the particular emblem of Osiris, and his sceptre ended with that figure. It was also the emblem of Hermes, and was considered a Sublime Hieroglyphic, possessing mysterious powers and virtues, as a wonder-working amulet.
The Sacred Tau occurs in the hands of the mummy-shaped figures between the forelegs of the row of Sphynxes, in the great avenue leading from Luxor to Karnac. By the Tau Cross the Cabalists expressed the number 10, a perfect number, denoting Heaven, and the Pythagorean Tetractys, or incommunicable name of God. The Tau Cross is also found on the stones in front of the door of the Temple of Amunoth III, at Thebes, who reigned about the time when the Israelites took possession of Canaan: and the Egyptian Priests carried it in all the sacred processions.
