The earliest complete pictorial stained-glass windows currently in existence are those found in the Cathedral of Augsburg in Germany. These windows, which feature five figures of prophets, date to the beginning of the 12th century.1

While fragments of what may be the earliest pictorial window were excavated at Lorsch, Germany, these are not complete. That reconstruction, which depicts a head of Christ, likely dates from the 9th, 10th, or 11th century.1
