London, that capital of the world, contains no examples of early glass _in situ_, and it is not until we have arrived at the study of Renaissance windows that she provides something to engage our attention. It must not be overlooked that there is an excellent collection of early glass at the Victoria and Albert Museum which, by the way, is most advantageously displayed, thanks to the manner in which all light is cut off save that coming through the coloured panes: it is unfortunate that the same good taste and judgment is not in evidence at the Louvre and other great museums. Some of the original mosaic medallions from the Sainte Chapelle, Paris, are here preserved. After all, though this South Kensington exhibit is undeniably good, glass appeals to one less in a museum than when seen in its natural home, a church. Two London churches have interesting examples of Renaissance glass, which, however, came from abroad, the east window in St. Margaret's, Westminster, and three in the east wall of St. George's, Hanover Square. Westminster Abbey is generally entered by the north transept door, and almost every one of its visitors overlooks the modest little parish church of St. Margaret, standing only a few paces off, so completely dwarfed and rendered almost insignificant is it by the imposing proportions of its impressive neighbour. Nevertheless, small as is this interior, it possesses a window which the Abbey would be proud to have, one of such pre-eminent excellence as to draw from Winston the statement that "the harmonious arrangement of the colouring is worthy of attention. It is the most beautiful work in this respect that I am acquainted with." It completely fills the large eastern embrasure, and one needs but a glance to recognise it as a Renaissance work of an excellent type. The three central lancets show Christ between the thieves, and below, the Holy Women, and soldiers. The drops of blood from His wounded side fall into chalices held by three angels. The repentant thief has his soul carried away by an angel to heaven, while a devil is mocking the other one. On the north side is St. George, and below him a kneeling figure which provides the only authentic portrait of Arthur Prince of Wales. On the left is Katharine of Aragon, the _fiancée_ of Prince Arthur, and later the first wife of Henry VIII. Above her head appears her badge, the pomegranate. As no stranger tale could be related of the vicissitudes to which a glass window could be subjected than the adventures of this window during the 300 years that elapsed between its making and its installation at St. Margaret's, the writer is moved to set it out in full in the words of the historian of that church, Mrs. J. E. Sinclair:
