Silesia was the leading literary landscape in the 17th century. The two cultural centers in Liegnitz and Brzeg made a significant contribution to this. Their princes participated intensively in the spiritual and religious life and were patrons of the arts and sciences. The German literature about Martin Opitz and his friends would not have gained supraregional importance if the Piast dukes had not given their support as patrons. The greatest of the century, a Gryphius, a Hofmannswaldau, a Lohenstein, they all put their pens at the service of this family. Poles and Germans had central locations in the Piasts and their wonderful residences for gaining identity. The cultural-historical and reader-friendly book by Klaus Garber aims to win back a rich Central European heritage of memory. Wroclaw is culturally flanked by Liegnitz and Brzeg. This triad is unique to the German cultural area.
