Lastly, the Empress asked the Bird-men of the nature of Thunder and Lightning? and whether it was not caused by roves of Ice falling upon each other? To which they answered, That it was not made that way, but by an encounter of cold and heat; so that an exhalation being kindled in the Clouds, did dash forth Lightning, and that there were so many rentings of Clouds as there were Sounds and Cracking noises: But this opinion was contradicted by others, who affirmed that Thunder was a sudden and monstrous Blaz, stirred up in the Air, and did not always require a Cloud; but the Empress not knowing what they meant by Blaz (for even they themselves were not able to explain the sense of this word) liked the former better; and, to avoid hereafter tedious disputes, and have the truth of the Phænomena's of Cœlestial Bodies more exactly known, commanded the Bear-men, which were her Experimental Philosophers, to observe them through such Instruments as are called Telescopes, which they did according to her Majesties Command; but these Telescopes caused more differences and divisions amongst them, then ever they had before; for some said, they perceived that the Sun stood still, and the Earth did move about it; others were of opinion, that they both did move; and others said again, that the Earth stood still, and Sun did move; some counted more Stars then others; some discovered new Stars never seen before; some fell into a great dispute with others concerning the bigness of the Stars; some said, The Moon was another World like their Terrestrial Globe, and the spots therein were Hills and Vallies; but others would have the spots to be the Terrestrial parts, and the smooth and glossie parts, the Sea: At last, the Empress commanded them to go with their Telescopes to the very end of the Pole that was joined to the World she came from, and try whether they could perceive any Stars in it: which they did; and, being returned to her Majesty, reported that they had seen three Blazing-Stars appear there, one after another in a short time, whereof two were bright, and one dim; but they could not agree neither in this observation: for some said, It was but one Star which appeared at three several times, in several places; and others would have them to be three several Stars; for they thought it impossible, that those three several appearances should have been but one Star, because every Star did rise at a certain time, and appear'd in a certain place, and did disappear in the same place: Next, It is altogether improbable, said they, That one Star should fly from place to place, especially at such a vast distance, without a visible motion; in so short a time, and appear in such different places, whereof two were quite opposite, and the third side-ways: Lastly, If it had been but one Star, said they, it would always have kept the same splendor, which it did not; for, as above mentioned, two were bright, and one was dim.
