Meanwhile the young king was reared in great seclusion in Stirling Castle, under the care of the celebrated scholar George Buchanan. His acquirements, at a very early age, were such as to raise great hopes of his future rule. Killegrew, the English ambassador, reports having heard him, at eight years of age, translate the Bible, _ad aperturam libri_, from Latin into French, and from French into English, ‘so well as few men could have added anything to his translation.’ But, in reality, his character was a strange mixture of cleverness and weakness, of wit and folly. His greatest deficiency was in a courageous will to pursue the ends of justice. He could clearly enough apprehend the disease, and speak and write about it plausibly; but he could do little towards its cure, because he shrank from all strong measures except against poor and inferior people, and those who had wounded his own pettier feelings. The regency of Morton came to a premature conclusion in consequence of a combination raised against him by the Earls of Athole and Argyle; and James became nominally the acting ruler (March 1578), ere he had completed his twelfth year. * * * * * [Sidenote: 1572. NOV. 18.] ‘... in the morning, was seen a star northward, very bright and clear, in the constellation of Cassiopeia, at the back of her chair; which, with three chief fixed stars of the said constellation, made a geometrical figure lozenge-wise, of the learned men called _rhombus_. This star, at the first appearing, seemed bigger than Jupiter, and not much less than Venus when she seemeth greatest ... the said star never changed his[84] place ... and so continued (by little and little appearing less) the space of sixteen months; at what time it was so small, that rather thought, by exercise of oft viewing, might imagine the place, than any eye could judge the presence of the same.’--_Holinshed._ [Sidenote: 1572.] This was the celebrated _Star of Tycho_, so called because Tycho Brahé made it the subject of observation. The Danish astronomer is known to have first observed it a few days before the date assigned by Holinshed--namely, on the 11th of November, while taking an evening walk in the fields. From the suddenness of its appearance, and its very great brightness, he suspected that his sense was deceived, and was only convinced he saw truly when he found some peasants gazing at the imposing stranger with as much astonishment as himself. It has been regarded as an example of a class of stars which move in periods between remote and comparatively near points in space; and as there was a similar object seen in 945 and 1264, it was supposed that the period of this star was somewhat over 300 years. But ‘the period of 300 years, which Goodriche conjectured, has been reduced by Kiell and Pigot to 150 years.’[85]
