"That miracle of a youth," Dr Christopher Wren, was one of those deputed by the University (1667) to take a letter of thanks to Henry Howard, heir to the Duke of Norfolk, for his princely gift of the Arundel Marbles to the University. This gift the University owed to the kindly offices of John Evelyn, the diarist. The marbles were laid in the Proscholium till the Sheldonian Theatre was finished. Ingeniously designed by Wren to accommodate the University at the "Act" or "Encænia," this theatre was consecrated by Archbishop Sheldon (1669), at whose cost it was erected. Sheldon was a warden of All Souls', put out under the Commonwealth and afterwards restored, before being promoted to the Primacy. Wren left many other marks of his genius upon Oxford. The chapel of B.N.C. is said to be from his design, and may be, for it reveals the struggle that was going on (1656) between the Oxford Gothic, as the beautiful fan-tracery of the ceiling and the windows bear witness, and the Italian style of the rest of the building. Wren migrated from Wadham to All Souls', presenting on his departure a clock (now in the ante-chapel) to the college where he had been a fellow-commoner. In the college of which he, with Sydenham, was made a fellow under the Commonwealth, he made the great and accurate sun-dial, with its motto "Pereunt et Imputantur," that adorns the back quadrangle. His pupil Hawksmoor it was who designed the twin towers of All Souls' and the quadrangle at Queen's, whilst Wren himself designed the chapel, which he reckoned one of his best works. At Trinity he gave advice to Dean Aldrich, made suggestions which were not taken, and actually designed the north wing of the garden quadrangle, one of the first Italian buildings in Oxford. At Christ Church he added, as we have seen, the octagonal cupola to Wolsey's Tower. The buttresses in Exeter Garden which support the Bodleian are also the result of his advice. The beautifully proportioned building close to the Sheldonian was presently built (1683, Wood, architect) by the University to house the valuable collection of curiosities presented to it by Elias Ashmole.
