The Merrie Tales of Jacques Tournebroche

The Emperor Charlemagne and his twelve peers, having taken the palmer's staff at Saint-Denis, made a pilgrimage to Jerusalem. They prostrated themselves before the tomb of Our Lord, and sat in the thirteen chairs of the great hall wherein Jesus Christ and his Apostles met together to celebrate the blessed sacrifice of the Mass. Then they fared to Constantinople, being fain to see King Hugo, who was renowned for his magnificence.
