It is strange that London fires--and London, in the middle ages, was specially prolific in fires--have never altered the course of the city's highways. Sir Christopher Wren wished, indeed, after the Great Fire of 1666, to be allowed to alter the plan of the desolated town and make it more symmetrically regular: with all due admiration of his genius, one cannot, however, help feeling a certain thankfulness that destiny averted his schemes, and that in the prosaic London of our own day we can still trace the splendour, the romance of its past. Thus, even in the grimy city "courts" we can still imagine a Roman "impluvium," or the ancient gardens of Plantagenet palaces; in the blind alleys of "Little Britain," the splendours of the merchants' mansions; in the ugly lines of mews and slums, the limits of the vanished Norman convent closes. The boundaries are still there, though nearly all else has gone. For, though Londoners are generally conservative with regard to their chief sites and the lines of their streets, they have, so far as their great buildings are concerned, always been by nature iconoclastic. Not that we of the present day need give ourselves any airs in this matter. Although, indeed, for the last half-century the spirit of antiquarian veneration has been abroad, yet the great majority of Londoners are hardly affected by it, and the pulling down of ancient buildings continues almost as gaily as ever at the present day. It may be said that we pull down for utilitarian reasons; well, so did our forefathers; Londoners have always been practical. Religious zeal may occasionally have served to whet their destructive powers, but the results are pretty much the same. Perhaps Henry VIII.--that Bluebeard head of the Church and State--has, in his general dissolution of the monasteries and alienation of their property, been the greatest iconoclast in English annals; yet even he must have been nearly equalled by the Lord Protector Cromwell, whose Puritanical train wrought so much havoc among London's monuments of a later age. Reforms and improvements, all through the world's history, have always been cruelly destructive. For, while churches and palaces were destroyed as relics of Popery, while works of art were demolished, and frescoes whitewashed in reforming zeal, fresh life was always sprouting, fresh energy ever filling up gaps, ever obliterating the traces of the past, the relics of the older time. Sir Walter Besant, in his picturesque and vivid sketch of English history, has realised well for us the city's past life:--
