In the ZhZL series, another book about the great German composer was published, this time written by a French author. The latter is not a musicologist; he is a journalist specializing in matters of Christianity and has written several books on contemporary issues of religion. And therefore, his view of Bach is precisely through the prism of the composer's religious views, which he considers extremely important for understanding his work. The author analyzes in detail the Christian symbolism of Bach's works, tells us about the role that music played in the then worship and how the culture of Europe in the first half of the 18th century was in close connection with religion. An important plot of the story is the correlation of two iconic figures of German history - Martin Luther and Johann Sebastian Bach.
