Wren went in due course to Westminster, and worked under the redoubtable Dr. Busby. His father’s choice of the school was doubtless due to the vehemently loyalist attitude of the great headmaster, but it may also have been influenced by the fact that Busby, though a notable classic, did not frown upon mathematical and scientific studies. Christopher was a Town Boy, and never entered the College proper. Possibly it was at Westminster that Wren first met Robert Hooke, with whom he was to be so closely associated in after life, though this guess is a little doubtful, for Hooke was older by three years; but he was also a Town Boy, and boarded in Busby’s house, going but little into school. John Sargeaunt thought that Hooke studied mathematics apart, and that this liberty was probably shared by young Christopher. It is likely that owing to Christopher’s delicate health he left Westminster early and pursued his studies under the eye of Sir Charles Scarborough, a young but famous physician who had developed a marked genius for mathematics and science. If Wren had remained at Westminster, he would almost certainly have proceeded in the ordinary course, like most Westminster boys, either to Christ Church, Oxford, or Trinity College, Cambridge: the choice of Wadham was no doubt dictated by his friendship with the Warden. Evidently, however, Wren retained an affection for his old school, because he took much trouble over the design of a new dormitory which led to a great deal of wrangling, and the work of building was postponed again and again. When, ultimately, the policy of rebuilding was settled in 1721, Wren was ninety, and no longer in practice. His design, therefore, was put aside, and the Earl of Burlington produced what purported to be a new one, but was, in fact, Wren’s, with some slight modifications. The existing building, in fact, which looks out on the quiet Abbey Garden, may be regarded as a work of Wren, though technically the amateur Burlington was responsible for it. If we are to believe Elmes, it was not until 1647, when Christopher was in his fifteenth year, that he became acquainted with Sir Charles Scarborough, but it seems more reasonable to ascribe to the Scarborough period, following Wren’s retirement from Westminster, a manuscript letter in Latin verse to his father, dated September 13, 1645, dedicating to him an instrument called _Suum Panorganum Astronomicum_, and a tract _De Ortu Fluminum_. On that assumption Christopher left Westminster before he had completed his thirteenth year. There is very little to show that Wren was much interested in the graphic arts, but on the sheet in the heirloom _Parentalia_ which contains the Latin letter is an ink sketch of a woman holding up a dial-shaped object, which is possibly the _Panorganum_.
