Nehalennia (spelled variously) is a goddess. Of unclear origin, perhaps Germanic or Celtic, Nehalennia is attested on and depicted upon numerous votive altars discovered around what is now the province of Zeeland, the Netherlands, where the Rhine River flowed into the North Sea. Worship of Nehalennia dates back at least to the 2nd century BC, and veneration of the goddess flourished in the 2nd and 3rd centuries AD.
Inscriptions and depictions 
Nehalennia is attested on 28 inscriptions discovered in the Dutch town of Domburg on the Zeeland coast, when a storm eroded dunes in 1645, disclosing remains of a temple devoted to the previously unattested goddess Nehalennia. A similar number were discovered in 1971-72 in the town of Colijnsplaat, and two others have been found in the Cologne-Deutz area of what is now Cologne, Germany.
Nehalennia, a Germanic goddess worshipped at the point where travellers crossed the North Sea from the Netherlands, is shown on many carved stones holding loaves and apples like a Mother Goddess, sometimes with a prow of a ship beside her, but also frequently with an attendant dog which sits looking up at her (Plate 5). This dog is on thirteen of the twenty-one altars recorded by Ada Hondius-Crone (1955:103), who describes him as a kind of greyhound.
Davidson further links the motif of the ship associated with Nehalennia with the Germanic Vanir pair of Freyr and Freyja, as well as the Germanic goddess Nerthus and notes that Nehalennia features some of the same attributes as the Matres.
The loaves that Nehalennia is depicted with on her altars have been identified as duivekatar, "oblong sacrificial loaves in the shape of a shin bone". Davidson says that loaves of this type may take the place of an animal sacrifice or animal victim, such as the boar-shaped loaf baked at Yule in Sweden, and that in Värmland, Sweden "within living memory" grain from the last sheaf was customarily used to bake a loaf into the shape of a little girl that is subsequently shared by the whole household. Davidson provides further examples of elaborate loaves—Harvest Loaves—at times in the shape of sheaves and displayed in churches, bread employed for the fertility of fields in Anglo-Saxon England with parallels in Scandinavia, and examples from Ireland.
The Domburg inscriptions to Nehalennia inspired Marcus Zuerius van Boxhorn to produce a hasty etymology linking the name Nehalennia to an ancient Scythian, with which he attempted, with the linguistic tools then available, to bridge the already-known connections between the European languages and modern Persian.
Religious practices surrounding Nehalennia were at their peak in the 2nd and 3rd centuries AD, at which time there were at least two to possibly three temples located in the area of what is now Zeeland. At the time, this region on the sea coast was an important link for the trade between the Rhine area and Britain. It is known that the tribe of the Morini, who lived on the North Sea coast, worshipped Nehalennia. Visitors came to worship from as far away as Besançon, France and Trier, Germany. Nehalennia had two sanctuaries or shrines, embellished with numerous altars: one at Domburg on the island of Walcheren, and another at Colijnsplaat on the shore of the Oosterschelde.
