151. They then represented their sanctuaries before the spirits of our earth, who said that they had seen nothing more magnificent; and as I also saw them, I can therefore describe them. They are constructed of trees, not cut down, but growing in their native soil. They said that on their earth there were trees of wonderful growth and height. These from their beginnings they arrange in order, so that they serve for porticos and walks, and by cutting and pruning the branches when they are tender, they fit and prepare them so that while they are growing they may intertwine and unite to make the base and floor of the sanctuary, and rise on the sides for the walls, and bend above into arches for the roof. By these means they construct the sanctuary with admirable art, elevated high above the earth, and they also prepare an ascent into it by successive branches of the trees extending out and firmly connected. Moreover they adorn the sanctuary without and within in various ways, by bending the leafy bows into various forms. Thus they build entire groves. But what these sanctuaries are within, I was not permitted to see. It was only told me that the light of their sun is let into them through apertures between the branches, and is here and there transmitted through crystals, by which the light falling on the walls is variegated into colors like the rainbow, especially the colors blue and orange, which they love more than the rest. Such is their architecture, which they prefer to the most magnificent palaces of our earth.
