According to a king asleep in mountain legend, Emperor Frederick Barbarossa, who actually drowned on 10 June 1190 in the Calycadnus River near Seleukeia in Asia Minor during the Third Crusade, is not in fact dead, but sleeps in a hidden chamber underneath the Kyffhäuser hills. He sits motionless at a stone table and his beard has supposedly grown so long over the centuries that it grew through the table. As in the similar legend of King Arthur, Barbarossa supposedly awaits his country's hour of greatest need, when he will emerge once again from under the hill. The presence of ravens circling the Kyffhäuser summit is said to be a sign of Barbarossa's continuing presence. Similar rapture legends refer to Emperor Frederick II or to Charlemagne sleeping in the Untersberg near Salzburg.
