 nearly a thousand times, and brought it more than thirty times nearer. Although, therefore, it is clear from this that the first idea of the telescope does not belong to Galileo, it is equally clear that he found out how to construct it from his own reflection and experiments. Undoubtedly also the merit of having made great improvements in it belongs to him, which is shown by the fact that at that time, and long afterwards, his telescopes were the most sought after, and that he received numerous orders for them from learned men, princes and governments in distant lands, Holland, the birthplace of the telescope, not excepted. But the idea which first gave to the instrument its scientific importance, the application of it to astronomical observations, belongs not to the original inventor but to the genius of Galileo. This alone would have made his name immortal.

A few days after he had constructed his instrument, imperfect as it doubtless was, he hastened with it to Venice, having received an invitation, to exhibit it to the doge and senate, for he at once recognised its importance, if not to the full extent. We will now let Galileo speak for himself in a letter which he wrote from Venice to his brother-in-law, Benedetto Landucci:—

"You must know then that about two months ago a report was spread here that in Flanders a spy-glass had been presented to Prince Maurice, so ingeniously constructed that it made the most distant objects appear quite near, so that a man could be seen quite plainly at a distance of two miglia. This result seemed to me so extraordinary that it set me thinking;
