And it is only natural that a healthy and ambitious young man trying to work his way to success would, or might have been, equally strenuous and self-denying. His appointment as Fellow of St. John’s was one of those made when the College was founded. That he was skilled in other branches of learning was shown by the fact that in the University he was appointed as Under Reader in Greek. He was daring in the practical application of science, and during the representation of one of the comedies of Aristophanes, created such a sensation by appearing to fly, that he began to be credited by his companions with magical powers. This was probably the beginning of the sinister reputation which seemed to follow him all his life afterwards. When once an idea of the kind has been started even the simplest facts of life and work seem to gather round it and enlarge it indefinitely. So far as we can judge after a lapse of over three hundred years, John Dee was an eager and ardent seeker after knowledge; and all through his life he travelled in the search wherever he was likely to gain his object. It is a main difficulty of following such a record that we have only facts to follow. We know little or nothing of motives except from results, and as in the development of knowledge the measure of success can only bear a small ratio to that of endeavour, it is manifest that we should show a large and tolerant understanding of the motives which animate the seeker for truth. In the course of his long life John Dee visited many lands, sojourned in many centres of learning, had relations of common interests as well as of friendship with many great scholars, and made as thinker, mathematician, and astronomer, a reputation far transcending any ephemeral and purely gaseous publicity arising from the open-mouthed wonder of the silly folk who are not capable of even trying to understand things beyond their immediate ken. Wherever he went he seems to have been in touch with the learned and progressive men of his time, and always a student. At various times he was in the Low Countries, Louvain (from whose University he obtained the degree of LL.D.), Paris, Wurtemberg, Antwerp, Presburg, Lorraine, Frankfort-on-the-Oder, Bohemia, Cracow, Prague, and Hesse-Cassel. He even went so far afield as St. Helena. He was engaged on some great works of more than national importance. For instance, when in 1582, Pope Gregory XIII instituted the reform of the Calendar which was adopted by most of the great nations of the world, Dee approved and worked out his own calculations to an almost similar conclusion, though the then opposition to him cost England a delay of over one hundred and seventy years. In 1572 he had proved his excellence as an astronomer in his valuable work in relation to a newly discovered star (Tycho Brahe’s) in Cassiopœia. In 1580 he made a complete geographical and hydrographical map of the Queen’s possessions. He tried--but
