The symbolical signs seen by Robert Schomburgk in the Valley of the Essequibo, near the rapids of Waraputa, (Richard Schomburgk, Reisen in Britisch-Guiana, Th. i. S. 320), were remarked by him to bear a great resemblance to genuine Carib ones in one of the small Virgin Islands (St. John’s); but notwithstanding the wide extent of the invasions of the Caribs, and the ancient power of this fine race, I cannot believe that all the rock engravings,--which, as I have said, form an immense belt traversing a great part of South America from west to east,--are to be regarded as their work. I am inclined rather to view these remains as traces of an ancient civilisation,--belonging, perhaps, to an epoch when the tribes whom we now distinguish by various appellations were still unknown. Even the veneration everywhere testified by the Indians of the present day for these rude sculptures of their predecessors, shews that they have no idea of the execution of similar works. There is another circumstance which should be mentioned: between Encaramada and Caycara, on the banks of the Orinoco, a number of these hieroglyphical figures are sculptured on the face of precipices at a height which could now be reached only by means of extraordinarily high scaffolding. If one asks the natives how these figures can have been cut, they answer, laughing, as if it were a fact of which none but a white man could be ignorant, that “in the days of the great waters their fathers went in canoes at that height.” Thus a geological fancy is made to afford an answer to the problem presented by a civilisation which has long passed away.
