Salvatores dei) is a series of "spiritual exercises" written by Greek author Nikos Kazantzakis.
It was first written between 1922 and 1923, while staying in Vienna and Berlin, and subsequently published in 1927 in the Athenian magazine Anayennisi (Renaissance).
Given the sacred tone of the book, which strives to go beyond philosophy and metaphysics, this introduction is better understood as an admonition.
According to Kimon Friar, the English translator of many of Kazantzakis' writings, The Saviors of God occupies a central role in the work of the Greek author.
In the second part of his lengthy introduction to The Odyssey: A Modern Sequel, Friar notes: Just before Kazantzakis began to write the Odyssey, he completed a small book, perhaps best titled The Saviors of God and subtitled Spiritual Exercises, where in a passionate and poetic style, yet in systematic fashion, he set down the philosophy embedded not only in the Odyssey but in everything he has written, for he was a man of one overwhelming vision, striving to give it shape in all the forms he could master, in epic, drama, novel, travelogue, criticism, translation, and even political action.
