and architecture in the second half of the 10th century depended on the court patronage of Otto and his immediate successors. The Ottonian Renaissance was manifest in some revived cathedral schools, such as that of Bruno I, Archbishop of Cologne, and in the production of illuminated manuscripts, the major art form of the age, from a handful of elite scriptoria, such as that at Quedlinburg Abbey, founded by Otto in 936. Extant manuscripts of this era are the Diploma Ottonianum, the Marriage Charter of Empress Theophanu, and the Gero Codex, an evangeliary drawn up around 969 for Archbishop Gero. The Imperial abbeys and the Imperial courts became centers of religious and spiritual life; prestigious convents like Gandersheim and Quedlinburg were led by women of the royal family. Modern world Otto I was selected as the main motif for a high value commemorative coin, the €100 Imperial Crown of the Holy Roman Empire commemorative coin, issued in 2008 by the Austrian Mint. The obverse shows the Imperial Crown of the Holy Roman Empire. The reverse shows Emperor Otto I with Old St. Peter's Basilica in Rome in the background, where his coronation took place. Among others, three exhibitions in Magdeburg, opening in 2001, 2006 and 2012, have documented Otto's life and his influence on medieval European history.
