Swedenborg's account of a third earth in the star-depths contains a very pretty idea for temples and churches. The temples in that earth 'are constructed,' he says, of trees, not cut down, but growing in the place where they were first planted. On that earth, it seems, there are trees of an extraordinary size and height; these they set in rows when young, and arrange in such an order that they may serve when they grow up to form porticoes and colonnades. In the meanwhile, by cutting and pruning, they fit and prepare the tender shoots to entwine one with another, and join together so as to form the groundwork and floor of the temple to be constructed, and to rise at the sides as walls, and above to bend into arches to form the roof. In this manner they construct the temple with admirable art, elevating it high above the ground. They prepare also an ascent into it, by continuous branches of the trees, extended from the trunk and firmly connected together. Moreover, they adorn the temple without and within in various ways, by disposing the foliage into particular forms; thus they build entire groves. But it was not permitted me to see the nature of these temples, only I was informed that the light of their sun is let in by apertures amongst the branches, and is everywhere transmitted through crystals; whereby the light falling on the walls is refracted in colours like those of the rainbow, particularly blue and orange, of which they are fondest. Such is their architecture, which they prefer to the most magnificent palaces of our earth.' Other earths in the starry heavens were visited by Swedenborg, but the above will serve sufficiently to illustrate the nature of his observations. One statement, by the way, was made to him which must have seemed unlikely ever to be contravened, but which has been shown in our time to be altogether erroneous. In the fourth star-world he visited, he was told that that earth, which travels round its sun in 200 days of fifteen hours each, is one of the least in the universe, being scarcely 500 German miles, say 2000 English miles, in circumference. This would make its diameter about 640 English miles. But there is not one of the whole family of planetoids which has a diameter so great as this, and many of these earths must be less than fifty miles in diameter. Now Swedenborg remarks that he had his information from the angels, 'who made a comparison in all these particulars with things of a like nature on our earth, according to what they saw in me or in my memory. Their conclusions were formed by angelic ideas, whereby are instantly known the measure of space and time in a just proportion with respect to space and time elsewhere. Angelic ideas, which are spiritual, in such calculations infinitely excel human ideas, which are natural.' He must therefore have met, unfortunately, with untruthful angels.
