"Rudolf Simek is critical of the approach, stating that "attempts have been made to interpret Odin's ravens as a personification of the god's intellectual powers, but this can only be assumed from the names Huginn and Muninn themselves which were unlikely to have been invented much before the 9th or 10th centuries" yet that the two ravens, as Odin's companions, appear to derive from much earlier times.Instead, Simek connects Huginn and Muninn with wider raven symbolism in the Germanic world, including the raven banner (described in English chronicles and Scandinavian sagas), a banner which was woven in a method that allowed it, when fluttering in the wind, to appear as if the raven depicted upon it was beating its wings.
