Hans Rookmaaker's impact on the arts in the 20th century was enormous. His wide range of intellectual and cultural concerns led him to explore many aspects of art, music and philosophy during his lifetime, and he made important contributions as an art historian, professor, mentor, thinker and author. Laurel Gasque examines Rookmaaker's life and shows how he incorporated his biblical beliefs into his teaching, writing, and interaction with the arts and individuals. She also explores the development of Rookmaaker's friendship with Francis A. Schaeffer and how each influenced the other, especially in grasping the vision that became L'AbriFellowship.
