Trinity College was founded in 1554 by Sir Thomas Pope. Its tower and chapel are Grecian, and the chapel has a most beautiful carved screen and altarpiece. The library contains a chalice that once belonged to St. Alban's Abbey. Kettel Hall, now a private dwelling, is a picturesque building in front of Trinity. On Broad Street, where Trinity stands, is also Balliol College, founded in the thirteenth century by John Balliol. None of the existing buildings are earlier than the fifteenth century, while the south front, with its massive tower, has just been rebuilt. It was here that the martyrs Cranmer, Latimer, and Ridley were burned. A little farther along the same street is St. John's College, which Sir Thomas White founded in 1557. It is fronted by a terrace planted with fine elms. Its quadrangles and cloisters are much admired, especially the venerable oriel windows and quaint stone gables of the library. St. John's gardens are regarded as among the most attractive in Oxford. Opposite St. John's are the university galleries, with their display of the Pomfret Marbles and Raphael and Michel Angelo's paintings and drawings, and behind this building is Worcester College, founded in 1714 by Sir Thomas Cookes. Its gardens contain a lake. Pembroke College is opposite Christ Church, and was founded in 1624 in honor of the Earl of Pembroke, then the chancellor of the university. While its entrance-gateway and hall, recently built, are fine, the other buildings are not attractive. The chief remembrance of Pembroke is of Dr. Samuel Johnson, who occupied apartments over the original gateway, but was compelled by poverty to leave the college before taking his degree. This completes the description of the colleges, halls, and schools of the great university, which presents an array of institutions of learning unrivalled in any part of the world, and of which Englishmen are justly proud.
