The Empress having received an information of what concerned both church and state, passed some time in viewing the imperial palace, where she admired much the skill and ingenuity of the architects, and enquired of them, first, why they built their houses no higher than two stories from the ground? They answered her Majesty, that the lower their buildings were, the less were they subject either to the heat of the sun, or wind, tempest, decay, etc. Then she desired to know the reason, why they made them so thick? They answered, that, the thicker the walls were, the warmer they were in winter, and cooler in summer; for their thickness kept out both cold and heat. Lastly, she asked, why they arched their roofs, and made so many pillars? They replied, that arches and pillars, did not only grace a building very much, and caused it to appear magnificent, but made it also firm and lasting.
