In general the mythological poems are strongly
heathen in character, and as Christianity became generally
accepted throughout Norway and Iceland early in the elev-
enth century, it is altogether likely that most of the poems
dealing with the Norse gods antedate the year 1000. On
the other hand, Hoffory, Finnur Jonsson and others have
shown pretty conclusively from linguistic evidence that
these poems cannot have assumed anything like their pres-
ent form before the ninth century. As for the poems be-
longing to the hero cycles, one or two of them appear to
be as late as 1100, but most of them clearly belong to the
hundred years following 950. It is a fairly safe guess that
the years between 900 and 1050 saw the majority of the
Eddie poems put into shape, but it must be remembered
that many changes took place during the long subsequent
period of oral transmission, and also that many of the
legends, both mythological and heroic, on which the poems
were based, certainly existed in Norway, and quite pos-
sibly in verse form, long before the year 900. In consider-
ing such poems it is essential to forget the present mode
of composition, whereby a poet at once fixes his thought
and his style by means of writing, and to remember that for
at least two centuries, and possibly much longer, the cor-
rect transmission of many of the Eddie poems depended
solely on accurate hearing and retentive memory."
