Julien Green's Journal abounds in precise, regularly noted references to his vast reading. Certain dominant trends can be noted in his choice of books. His choice favours titles which have spiritual themes, Anglo-Saxon literature, poetry, books on art and autobiographical writings. In the domain of spiritual literature he reveals a particular affinity with Port-Royal and Pascal. While this affinity with the seventeenth century is well known, Green's reading of Bossuet has been largely ignored. As this year marks the tercentenary of Bossuet's death, it may be of interest to explore his comments on his readings of the Bishop of Meaux. We will concentrate on certain themes which have an appeal for Green, but we will note above all his comments on the tone and style in which they are rendered.
