The apostleships of Ansgarius in Denmark, the conversion of King Eric, the Christianity of several later Danish Kings, one of whom was (like Olaf Tryggwason) baptised in Britain are also noticed.
Of "Christian legends" and beliefs, besides the euhemerist theory, widely held, of the heathen gods there are few hints, save the idea that Christ was born in the reign of Frode, Frode having been somehow synchronised with Augustus, in whose reign also there was a world-peace.
Of course the christening of Scandinavia is history, and the mythic books are little concerned with it.

The episode in Adam of Bremen, where the king offers the people, if they want a new god, to deify Eric, one of their hero-kings, is eminently characteristic and true.
FOLK-TALES.
There might be a classification of Saxo's stories akin to that of the Irish poets, Battles, Sieges, Voyages, Rapes, Cattle Forays, etc.; and quite apart from the historic element, however faint and legendary, there are a set of stories ascribed by him, or rather his authorities, to definite persons, which had, even in his day, probably long been the property of Tis, their original owners not being known owing to lapse of time and the wear of memory, and the natural and accidental catastrophies that impair the human record.

Such are the "Dragon-Slayer" stories.

In one type of these the hero (Frithlaf) is cast on a desolate island, and warned by a dream to attack and slay a dragon guarding treasure.

He wakes, sees the dragon arise out of the waves, apparently, to come ashore and go back to the cavern or mound wherein the treasure lay.
