North of Tiahuanuco is Lake Titicaca. This was the sacred lake of the Incas. We have already referred to the probable origin of this feeling. Near the southern end of this lake, on the western side, is the peninsula of Copacabana. Separated by a narrow strait from the northern extremity of this peninsula is the sacred island, Titicaca. According to traditions, the Incas sought, in all ways, to beautify this island. They built temples, and laid out gardens. The hills were leveled as much as possible, terraced, and then covered with earth brought from afar. According to the statements of early writers, pilgrims were not permitted to land on its sacred soil until they had undergone certain preliminary fasts and purifications on the main-land. Landing on the island, they traversed a terrace, and by a narrow passage way they were conducted between two large buildings, where other ceremonies were performed.
The most sacred spot in all the island was a rock in the northern part. Only priests of especial sanctity were allowed near it. The rock to-day presents but the appearance of a weather-worn mass of red sandstone. It is traditionally represented as having been plated all over with gold and silver, and covered, except on solemn occasions with a mantle of rich color and material. Here the sun was believed to have first risen to dispel the primal darkness. To this day the Indians regard it with superstitious veneration. The traveler’s guide, when he comes in sight of it, removes his hat, and reverently bows to it, and mutters to himself a few words of mystic import.44
The whole appearance of the island shows how highly it was regarded. In one place the remains of a drinking fountain were noticed. Streams from some unknown source were still bringing to it their limpid burden. Perhaps as noticeable a ruin as any is represented in this cut. It is called the Palace. It is in a sheltered nook. The lake washes the very foot of the foundation on which it stands. It is two-storied. In the lower story were twelve rooms, so connected with each other that but four of them communicated by doors with the outside. The others were certainly dark and illy ventilated. The second story was entered by means of the terrace in the rear. The same statement may be made in regard to its rooms; they did not, however, at all correspond in arrangement with the rooms below. The Island of Coati, but a short distance to the south-east, was sacred to the moon. It has also a number of ruins. The approach to this was guarded by a number of terraces.
We will describe one more class of ruins found abundantly in the Collao region. These are burial towers, or chulpas. A view of one is here presented. The chulpas are common in the Titicaca basin, and usually occur in groups, and almost always in positions from which a large extent of country can be viewed. The great mass of a chulpa is solid, but within is a dome-shaped chamber, into which the opening seen in the cut leads. Sometimes the chulpas are round, and in some the masonry is of that variety we have already mentioned, called the Cyclopean. Another view of burial towers is given earlier in this chapter.
