When Ignatius de Loyola wrote his Spiritual Exercises, his work was a result of the tradition which was cumulated during several generations. This tradition can be called as a spiritual materialism. Spiritual materialism was an attitude with expectation that we can reach the sacred through the material thing, The material thing can encompass from the relique to some images. We can ask some Questions. ``How does this spiritual materialism form Ignatian Spiritual Exercises? And Why?`` These Questions are concerned with issues such as the formation of the Spiritual Exercises. the motivation of the S.E.. and the historical background of the S.E. This short essay was written to answer these Questions. The originality of Ignatian S.E. was not the invention of the picturesque contemplation that one uses his senses and images positively in one`s prayer. Before Ignatian S.E .. some spiritual traditions such as Meditationes de Vita Christi. Vita Christi and Legenda Aurea have influenced deeply among medieval Christians. Ignatius de Loyola also was one among the medieval souls. Right before the conversion, he was deeply influenced by the Vita Christi and Legenda Aurea. Materialism in S.E. was a cumulative outcome of these traditions. In Ignatian Spiritual Exercises. we can find these materialism in his applicatio sensuus. S.E. encouraged one in contemplation to use one`s senses in order to immerse oneself into the contemplation. If we closely examine biographical facts of Ignatius de Loyola. we can find that historical context is an important key for understanding Ignatian spiritual materialism. He was a homo viator who was confined between the heavenly world and the secular world. Homo viator who has double citizenship of the knightly city and the monkly city. Homo viator who has lived in both chivalric world and ascetic world. I think that this sense of instability which was condensed within homo viator formed Ignatian spiritual materialism. In this point of view. Ignatius` emphasis on the application of senses and images can be easily understood.
