Their father, Niiir6r, the god of wealth, who is a somewhat less important figure, corresponds in name to the goddess Nerthus (Hertha), who in ancient times was worshipped by a number of tribes, including the Angli, round the coasts of the southern Baltic. Tacitus describes her as " Mother Earth," and the account which he gives of her cult bears a somewhat remarkable resemblance to the ceremonies associated in later times with Frey.
There can be little doubt that from a remote antiquity Zealand had been a religious sanctuary, and very probably the god Nerthus was worshipped here by the Angli and other tribes as described in Tacitus (Germania, c. 40).
In the Stubbenitz and elsewhere Huns' or giants' graves are common; and near the Hertha Lake are the ruins of an ancient edifice which some have sought to identify with the shrine of the heathen deity Hertha or Nerthus, referred to by Tacitus.
He gives no precise indication of their geographical position, but states that, together with six other tribes, including the Varini (the Warni of later times), they worshipped a goddess named Nerthus, whose sanctuary was situated on "an island in the Ocean."
The evidence for this view is derived partly from English and Danish traditions dealing with persons and events of the 4th century (see below), and partly from the fact that striking affinities to the cult of Nerthus as described by Tacitus are to be found in Scandinavian, especially Swedish and Danish, religion.
Investigations in this subject have rendered it very probable that the island of Nerthus was Sjaelland (Zealand), and it is further to be observed that the kings of Wessex traced their ancestry ultimately to a certain Scyld, who is clearly to be identified with Sk16ldr, the mythical founder of the Danish royal family (Skidldungar).
