In this book, Joseph Masheck re-examines the spiritual in Mondrian's art and proposes a parallel between the equilibrium found in his paintings and his writings on theological justification. The artist's Calvinist Christianity is considered in respect to the balanced, asymmetrical works of his 'classic' phase of the 1920s and 1930s, and potential parallels with the writings of an important Dutch theologian of the Neo-Calvinist movement are explored. Finally, the author follows Mondrian's classic phase into the 1930s and beyond, in this extraordinary and inspiring reassessment of one of the fathers of abstract art.
