A very ancient civilization existed on the shores of lake Titicaca long before the appearance of the first Inca of Peru; the principal remains of which are to be found at Tiahuanaco,[149] near the southern shore of the lake of Huaqui. An extensive tract is here covered by huge blocks of carved stone. It was with much regret that I was obliged, by my duty, to give up my intention of visiting these interesting remains. M. de Castelnau mentions two colossal statues of a man and a woman, crowned with a kind of turban; a colossal head and a lizard carved on blocks of stone; a great conical artificial hill; and a monolithic doorway, the upper part of which is covered with very curious sculpture. In the centre there is a figure, probably representing the Sun, and on each side a number of figures all turned towards it, with wings, and sceptres in their hands: those on one side with their heads crowned, and those on the other with heads of griffins, and the bodies adorned with garlands of human heads.[150] All who have visited these ruins consider them to be of a distinct character from those of Cuzco, and other works of the Incas. The stones are more richly carved, and many of them have been united by means of a metal poured into transverse grooves. M. de Castelnau considers that the chief characteristic of Aymara ruins is the minute detail in the carving on the stones, while that of the Incas consists in the grand simplicity of the masonry.[151]
THE TOWERS OF SILLUSTANI.

On the islands of Titicaca and Coati there are also extensive ruins, the remains of temples and convents of virgins dedicated to the worship of the Sun and Moon; and Dr. Weddell mentions that there is a kind of phlox on these islands (Cantua buxifolia), its very elegant long scarlet flower being called by the Aymara Indians the "flower of the Incas."[152]
Although I was unable to visit either the ruins at Tiahuanaco or those on the islands, I found time to examine ruins of the same character on the shores of the lake of Umayu near Vilque, where the great cemetery of the chiefs of the Aymara tribes of the Collao appears to have been. These ruins are at a place called Sillustani, on the north side of the lake of Umayu, where a high rocky table-land juts out so as to form a peninsula, which is literally covered with places of sepulture. Four of them are towers of finely-cut masonry, equal to that of Cuzco, with the sides of the stones dovetailing into each other. On climbing up the steep rocky path which leads to the table-land, the first on the right-hand side is perched on the very edge of the northern precipice. Half of it is destroyed, the other half is of well-cut stones, with a broad rounded cornice near the summit, and a vaulted roof, part of which remains entire. In the interior, near the foundation, there is a vaulted chamber entered by a small aperture, and full of human bones. The rest of the tower was filled up with small stones and earth, leaving a narrow shaft which ascended from the chamber to the summit, down which the bodies may have been lowered into the chamber.
On the left there is another smaller tower of exactly similar construction. Further on, and near the verge of the southern precipice, there are two other towers close together. One is thirty-six feet high, and built of the same well-cut masonry, with a cornice and vaulted roof, and a great lizard carved in relief on one of the stones near the base, which measures six feet by three.[153] The other tower was apparently exactly similar, but it is now in a very ruinous state.
Besides these more remarkable edifices, the table-land is covered with other towers of rough unhewn stone and earth, and there are the remains of two square edifices built of cyclopean stones. The fallen parts of the towers were covered with masses of bright yellow compositæ called suncho, and a purple solanum; and they were frequented by the creepers called haccacllo, little green paroquets, a small quail called pucupucu, and the little ground-dove cullca; numbers of biscache rabbits burrowed in the ruins, while two or three lordly coraquenques soared in circles over the table-land. After carefully examining the old towers of Sillustani, I passed the night in a very small hut, close to the lake of Umayu, the waters of which were smooth as glass, an island in the centre, and blue ranges of mountains capped with snow in the distance. To get into the hut it was necessary to go on hands and knees, the doorway being only three feet high, with a hide door stretched on a wooden frame. The hut was built of rough stones and thatched with barley-straw; but inside there was a hospitable welcome and good cheer: the old Indian who dwelt there, and his young daughter, providing excellent boiled potatoes, cream-cheese, and fresh milk.
The ruins of Tiahuanaco, and on the islands in the lake, and the towers of Sillustani, are the principal remains of ancient Aymara civilization. Nothing is known respecting the people who raised these imperishable monuments, except that, in the middle of the eleventh century, a man and woman, declaring themselves to be children of the Sun, are said to have first appeared on the shores of the great lake, and, marching north, to have founded the empire of the Incas. The circumstance that Manco Ccapac, the first Inca of Peru, originally appeared in the country of the Aymaras, has led to the belief that he was himself a chief of that nation; but I am more inclined to the opinion that he was one of a band of adventurers who had been brought from Asia, or her vast archipelago of islands, by the westerly winds of the South Pacific, and the southerly breezes of the coast, to the port of Arica; that he thence made his way to the banks of the great lake, where he became indoctrinated in the religion of the people; and that, for some reason, he continued his wanderings, until he finally collected a sufficiently numerous following to found an independent state at Cuzco. It seems certain, from emblems found carved upon the ruins, and from tradition, that the worship of the Sun and Moon was established amongst the Aymaras for ages before the conquest of their country by the Incas of Cuzco.
It was not for several generations after the foundation of the empire of the Incas, that their conquests were extended over the Aymara nation of the Collao; and it was not until about the middle of the eleventh century that the country on the shores of lake Titicaca became part of the great empire whose centre and capital was at Cuzco. From that time the islands of Titicaca and Coata, and the peninsula of Copacabana, became the most sacred and venerated spots within the dominions of the Incas; as the localities where their great progenitor Manco Ccapac was believed to have made his first appearance.
