Orendel is a Middle High German poem, a Spielmannsdichtung, traditionally dated to the end of the 12th century, although the earliest known manuscript (no longer extant) was from 15th century.
The story is associated with the town of Treves ( Trier), where the poem was probably written. The introduction narrates the story of the Holy Coat, which, after many adventures, is swallowed by a whale. It is recovered by Orendel, son of King Eigel of Treves, who had embarked with twenty-two ships in order to woo Bride, the mistress of the Holy Sepulchre, as his wife. Suffering shipwreck, he falls into the hands of the fisherman Ise, and in his service catches the whale that has swallowed the Holy Coat. The coat has the property of rendering the wearer proof against wounds, and Orendel successfully overcomes innumerable perils and eventually wins Bride for his wife. A message brought by an angel summons both back to Treves, where Orendel meets with many adventures and at last disposes of the Holy Coat by placing it in a stone sarcophagus. Another angel announces both his and Brida's approaching death, when they renounce the world and prepare for the end.
The single manuscript of the poem no longer exist, but there are two prints (one verse, one prose) from 1512. These prints were made to coincide with the rediscovery of the seamless robe of Christ in Trier cathedral by Maximilian I. It has been edited by von der Hagen (1844), L. Ettmüller (1858) and A. E. Berger (1888); there is a modern German translation by K. Simrock (1845). See H. Harkensee, Untersuchungen über das Spielmannsgedicht Orendel (1879); F.
