The Armorial of Conrad von Grünenberg is a splendid manuscript containing several hundred colored coats of arms. It was written on parchment and seems to be a contemporary copy from the original version on paper written in 1483, preserved today in Berlin. It formed part of the library of the dukes of Bavaria and was probably in the possession of Duke Wilhelm IV of Bavaria (1493−1550). Depicted are the coats of arms of barons, dukes, margraves, archbishops, free cities and towns, and orders of knights from throughout Germany, as well as the royal coats of arms of the kingdoms of Europe. Konrad Grünenberg was an important burgher and knight and a descendant of a patrician dynasty from Konstanz, located on Lake Constance in southwestern Germany. There is no evidence for the exact date of his birth or death. His name first appears when he is mentioned as a builder commissioned by the town of Konstanz in 1442. Grünenberg occupied himself with heraldry and composed the armorial that came to bear his name. Several copies later were produced from Grünenberg’s original autograph copy, including this contemporary copy.
