For larger buildings a definite Greek Revival was now beginning to take form within the general frame of Romantic Classicism. More young architects were visiting Greece and, for those who could not, two further volumes of Stuart and Revett’s _Antiquities of Athens_, appearing in 1787 and in 1794, and the parallel _Ionian Antiquities_, which began to be issued in 1769, provided many more models for imitation than had been available earlier. The Greek Doric order had first been introduced into England by Stuart himself in 1758 in the Hagley Park temple, as has been mentioned earlier; a little later, in 1763, he used the Greek Ionic on Litchfield House which still stands at 15 St James’s Square in London. From the nineties, the Greek orders were in fairly common use, as such a splendid group as the buildings of Chester Castle, of 1793-1820 by Thomas Harrison (1744-1829), handsomely illustrates. However, the handling of them was not as yet very archaeological. Summerson credits the attack made by the connoisseur Thomas Hope (1770?-1831) in 1804 on Wyatt’s designs for Downing College, Cambridge, with helping to establish a more rigid standard of correctness. However that may be, the winning and partly executed design of 1806-11 for this college by William Wilkins (1778-1839) well illustrates the new ideals. Wilkins had made his own studies of Greek originals in Sicily and Southern Italy, and was publishing them in the _Antiquities of Magna Graecia_ at this very time (1807). The inherited concepts of medieval college architecture, largely maintained through the earlier Georgian period, were all but forgotten at Downing. The group was broken down into free-standing blocks, each as much like a temple as was feasible, and repeated Ionic porticoes provided almost the only architectural features. There was no Soanic originality here, no Picturesque eclecticism; perhaps unfortunately, however, this provided a codified Grecian mode which almost anyone could apply from handbooks of the Greek orders. Wilkins was also responsible for the first[21] British example of a giant columnar monument, the Nelson Pillar of 1808-9 in Dublin. This 134-foot Greek Doric column in Sackville (now O’Connell) Street, of which the construction was supervised by Francis Johnston (1760-1829), initiated a favourite theme of the period usually, and not incorrectly, associated with Napoleon (see Chapter 3).
