The names vary from manuscript to manuscript. Snorri tells us that Yggdrasil's third root 'stands in heaven and beneath this root is a spring called Urd's Well'. . . . Nothing is known of the rivers in this strophe. It is hard to reconcile this with the information in strophe 29. Some editors consider the root of 29 to be the second one enumerated here.
Nothing is known of the harts or the serpents mentioned here.
The list of Valkyrie names given here differs in many respects from that of ' Song of the Sybil '. This passage parallels that in the 'Lay of Vafthrudnir '. 42 Invaldi is the progenitor of all craftsmen-dwarves. Nothing is known of this episode. It may be noted here that the German scholar Genzmer silently elides seventeen strophes from this poem - thus eliminating many problems.
