Scholars of different faculties (Theology, History, Education, Literature, Music) met in 2017 with the common aim to understand more deeply the life and works of Johann Gottfried Herder (1744-1803). He was a man of the Church and worked literally under a portrait of Martin Luther, to whom he felt indebted for the whole of his life, even as a man of the enlightenment. He was called "the theologian among the classics", he worked in close contact with Goethe, Schiller and Wieland in Weimar, he frequented the court, was part of an urban society and headmaster of the school. On the other hand he was engaged in the task of transforming the Protestant legacy according the needs of an enlightened and secular society.
