Nerthus

In Germania, Tacitus mentions that the Lombards and Suebi venerated a goddess, Nerthus, and describes the rites of the goddess in some detail. At their center is a ceremonial wagon procession. Nerthus's cart is found on an unspecified island in the "ocean", where it is kept in a sacred grove and draped in white cloth. Only a priest may touch it. When the priest detects Nerthus's presence by the cart, the cart is drawn by heifers. Nerthus's cart is met with celebration and peacetime everywhere it goes, and during her procession no one goes to war and all iron objects are locked away. In time, after the goddess has had her fill of human company, the priest returns the cart to her "temple" and slaves ritually wash the goddess, her cart, and the cloth in a "secluded lake". According to Tacitus, the slaves are then immediately drowned in the lake.

The majority of modern scholars identify Nerthus as a direct etymological precursor to the Old Norse deity Njörðr, attested over a thousand years later. However, Njörðr is attested as male, leading to many proposals regarding this apparent change, such as incest motifs described among the Vanir, a group of gods to which Njörðr belongs, in Old Norse sources.
