Not who you're looking for? Others named Nibelungenlied: Middle High German epic poem from around 1200
“Des todes waffen ie ce sere sneit.”
“Der Nibelungen Lied könnte die deutsche Ilias werden.”
“Was aber Lebendigkeit und Gegenwart der Darstellung, dann die Größe der Leidenschaften [und] Charaktere…darf sich das Lied der Nibelungen kühnlich mit der Ilias messen.”
“The Nibelungen Song, though based on the bottomless foundations of Spirit, and not unvisited of skyey messengers, is a real, rounded, habitable Earth, where we find firm footing, and the wondrous and the common live amicably together. Perhaps it would be difficult to find any Poet of ancient or modern times, who in this trying problem has steered his way with greater delicacy and success.”
