In support of the theory of the south-continental origin of the Caribs we have, in the first place, the work of Mr. Aristides Rojas on Venezuelan hieroglyphics, wherein he treats of numerous Carib characters on the rocks along the plains and rivers of that republic, marking their itinerary from east to west. He states that the Acháguas, the aboriginals of Columbia, gave to these wanderers, on account of their ferocity, the name of Chabi-Nabi, that is, tiger-men or descendants of tigers. In the classification of native tribes in Codazzi's geography of Venezuela, he includes the Caribs, and describes them as "a very numerous race, enterprising and warlike, which in former times exercised great influence over the whole territory extending from Ecuador to the Antilles. They were the tallest and most robust Indians known on the continent; they traded in slaves, and though they were cruel and ferocious in their incursions, they were not cannibals like their kinsmen of the lesser Antilles, who were so addicted to the custom of eating their prisoners that the names of cannibal and Carib had become synonymous." [90] Another theory of the origin of the Caribs is that advanced by M. d'Orbigny, who, after eight years of travel over the South American continent, published the result of his researches in Paris in 1834. He considers them to be a branch of the great Guaraní family. And the Jesuit missionaries, Fathers Raymond and Dutertre, who lived many years among the Antillean Caribs, concluded from their traditions that they were descended from a people on the continent named Galibis, who, according to M. d'Orbigny, were a branch of the Guaranís. But the Guaranís, though a very wide-spread family of South American aborigines, were neither a conquering nor a wandering race. They occupied that part of the continent situated between the rivers Paraguay and Paraná, from where these two rivers join the river Plate, northward, to about latitude 22° south. This region was the home of the Guaranís, a people indolent, sensual, and peaceful, among whom the Jesuits, in the eighteenth century founded a religious republic, which toward the end of that period counted 33 towns with a total population of over one hundred thousand souls. A glance at the map will show the improbability of any Indian tribe, no matter how warlike, making its way from the heart of the continent to the Orinoco through 30° of primitive forests, mountains, and rivers, inhabited by hostile tribes.[91]
