Influences upon Gothic architecture

The Gothic style of architecture was strongly influenced by the Romanesque architecture which preceded it. Why the Gothic style emerged from Romanesque, and what the key influences on its development were, is a difficult problem for which there is a lack of concrete evidence because medieval Gothic architecture was not accompanied by contemporary written theory, in contrast to the 'Renaissance' and its treatises.
