But it is necessary to consider other evidence. R. B. Gardiner, in _Registers of Wadham College_, notes that Wren’s caution money as Fellow Commoner was received on June 25, 1649 _or_ 1650. Sir Thomas G. Jackson gives 1649 as the year when Wren entered the college as Fellow Commoner. Wilkins did not become Warden, in place of Dr. Pitt, expelled by the Parliamentary Visitors, until April 13, 1648, when his name was entered in the Buttery Book. On May 5, 1648, Wilkins had a dispensation for twelve months from the full performance of his duties in consequence of his attendance on the Prince Elector, whose Chaplain he was. It was not impossible that Wren should have gone to Wadham at fourteen--the profligate Rochester matriculated at twelve and was M.A. before he was fourteen--but it is unlikely. Wren was exceedingly delicate as a boy, there was no Wilkins at Wadham to attract him there when he was fourteen or for two years after, and he was, even in 1649, the first Fellow Commoner entered during Wilkins’ wardenship. If Wilkins took the year’s leave granted him, and if June 25, 1649, be taken as the correct date for the payment of Wren’s caution money, he went there a month after the Warden settled down in his post. If Wren had proceeded direct to Oxford at fourteen from being under Busby at Westminster, he would almost certainly have gone to Christ Church, not to Wadham. Moreover, it is certain that during his sixteenth year, and perhaps later, he was very busy with mathematics and science under Sir Charles Scarborough in London. It is just conceivable that he entered at Wadham soon after Oxford surrendered to the Parliament in 1646, and that he did not come into residence until 1649 or 1650, but no document has ever suggested that, and the theory can be dismissed. It is the opinion of Mr. Wells, the reigning Warden, that if Wren only matriculated in 1650 he could not have proceeded to his B.A. in 1651, as in fact he did. But the year 1649, accepted by Sir Thomas Jackson, is feasible on the basis of Wren’s notable precocity and the then readiness of the University not to insist on three years, as is seen by Rochester’s case. It is, however, fair to add that the entry of Wren’s £5 in the Wadham book is undated, but it comes at the foot of a page headed 1650, on which the preceding entry is dated June 25, and the three previous names are registered by Gardiner as 1650. It may be, however, that as the Wren entry is undated, it was added later. On the other hand, if he had gone to Oxford in 1646 he could scarcely have occupied the then unheard-of time of five years before taking his B.A., March 18, 1650-51.
