The"mobility turn"within the social sciences at the start of 21st century has formed a"new mobilities"paradigm and aroused keen attention in the field of literary research.Mediations of mobility represented by mobilities in transportation is one of the basic dimensions of mobility re-search in literature.In Joyce's A Portrait of the Artist as a Young Man and Ulysses,Dublin's mode of transport underwent a transformation from traditional horse-drawn carriage to trams and trains that embodied the fruits of industrial and technological revolution.The process of Irish modernization from the perspective of mediations of mobility has reshaped the modern living space and spiritual world of Irish people,showing the new mobile perception and psychological experience brought by the new speed and rhythm.Joyce's meticulous observations and positive descriptions of emerging urban transport technologies,which paint a modern Dublin city image of technological cooperation and innovation,have dramatically changed European prejudices about Ireland's industrial and socio-cultural backwardness.
