12. When they were brought to the palace, they first of all viewed it from outside. It was spacious, built of porphyry with foundations of jasper. In front of the gate were six lofty columns of lapis lazuli, the roof was made of gold plates, there were high windows of the most transparent crystal, and the window-frames too were of gold. After seeing the outside, they were allowed inside the palace, and taken on a tour of the rooms; there they saw ornaments of indescribable beauty, and under the ceilings decorations of unrivalled carving. Near the walls tables were placed made of silver alloyed with gold, on which was a variety of equipment made of precious stones, and some items made out of solid gems cut into heavenly shapes. There was more, things no eye on earth has ever seen, so that no one could possibly believe that heaven contained such wonders.
[2] While they were stunned by the magnificence of what they had seen, the angel said: 'Do not be surprised. These things you see were not made or crafted by the hand of any angel. They are the work of the Craftsman of the universe, given as a present to our prince. This therefore is architecture at its highest, and it is from this that all the rules of architecture in the world derive. You may judge,' the angel went on, 'that such things fascinate our eyes and so dazzle them that we think those are the joys of our heaven. But because our hearts are not set on them, they are only extras added to the joys of our hearts. Thus in so far as we look on them as extras, and as God's handiwork, so far do we see in them the omnipotence and mercy of God.'
