The image of London as a human body is striking and singular; we may trace it from the pictorial emblems of the City of God, the mystical body in which Jesus Christ represents its head and the citizens its other members. London has also been envisaged in the form of a voting man with his arms outstretched in a gesture of liberation; the figure is taken from a Roman bronze but it embodies the energy and exultation of a city continually expanding in great waves of progress and of confidence. Here might be found the "heart of London beating warm".
