[175] _Identical_.--First, "because the _Lia Fail_ is spoken of by all ancient Irish writers in such a manner as to leave no doubt that it remained in its original situation at the time they wrote." Second, "because no Irish account of its removal to Scotland is found earlier than Keating, and he quotes Boetius, who obviously wished to sustain the claims of the Stuarts." The pillar-stone is composed of granular limestone, but no stone of this description is found in the vicinity. As may be supposed, there are all kinds of curious traditions about this stone. One of these asserts that it was the pillar on which Jacob reposed when he saw the vision of angels. Josephus states that the descendants of Seth invented astronomy, and that they _engraved their discoveries on a pillar of brick and a pillar of stone_. These pillars remained, in the historian's time, in the land of Siris.--_Ant. Jud_. l. 2, § 3. [176] _At once_.--See Petrie's _Tara_, p. 213. [177] _Roads_.--See Napoleon's _Julius Cæsar_, vol. ii. p. 22, for mention of the Celtic roads in Gaul. [178] _Chariots_.--St. Patrick visited most parts of Ireland in a chariot, according to the Tripartite Life. _Carbad_ or chariots are mentioned in the oldest Celtic tales and romances, and it is distinctly stated in the life of St. Patrick preserved in the Book of Armagh, that the pagan Irish had chariots. Different kinds of roads are expressly mentioned, and also the duty of road-mending, and those upon whom this duty devolved. See Introduction to the Book of Rights, p. 56.
