In Germanic paganism, Nerthus, is a goddess associated with a ceremonial wagon procession. Nerthus is attested by first century A.D. Roman historian Tacitus in his ethnographic work Germania.
In Germania, Tacitus records that a group of Germanic peoples were particularly distinguished by their veneration of the goddess. Tacitus describes the wagon procession in some detail: 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.
Scholars have linked Tacitus's description of ceremonial wagons found from around Tacitus's time up until the Viking Age, particularly the Germanic Iron Age Dejbjerg wagon in Denmark and the Viking Age Oseberg ship burial wagon in Norway. The goddess's name Nerthus (from Proto-Germanic *Nerþuz) is the early Germanic etymological precursor to the Old Norse deity name Njörðr, a male deity who is comparably associated with wagons and water in Norse mythology. Together with his children Freyja and Freyr, the three form part of the Vanir, a family of deities. The Old Norse record contains three narratives featuring ritual wagon processions that scholars have compared to Tacitus's description of Nerthus's wagon procession, one of which (and potentially all of them) focus on Njörðr's son Freyr.
Additionally, scholars have sought to explain the difference in gender between the early Germanic and Old Norse forms of the deity, discussed potential etymological connections to the obscure female deity name Njörun, mention of the mysterious sister-wife of Njörðr, proposed a variety of locations for where the procession may have occurred (generally in Denmark), and considered Tacitus's sources for his description.
Tacitus's Nerthus has had some influence on popular culture, and in particular the now widely rejected manuscript reading of Hertha in Germany.
Etymology
Scholars commonly identify the goddess Nerthus with Njörðr, a deity who is attested in Old Norse texts and in numerous Scandinavian place names. A major reason for this is etymology: Scholars identify the Romano-Germanic Nerthus as the exact expected linguistic precursor to the Old Norse deity name Njörðr and have reconstructed the form as Proto-Germanic *Nerþuz. As outlined by philologist John McKinnell, "Nerthus > *Njarðuz (breaking) > *Njǫrðuz > Njǫrðr". Scholars have additionally linked both Nerthus and Njörðr to the obscure Old Norse goddess name Njörun.
The meaning of the theonym is unclear, but seems to be cognate with Old Irish nert, meaning 'strength', perhaps meaning 'the powerful one'. The name may be related to Old English , meaning 'contented', and the Old English place name Neorxnawang, used to gloss the word 'paradise' in Old English texts, or the word north. According to philologist Jaan Puhvel, "*Nerthuz is etymologically ambivalent, cognate not only with Old Irish nert 'strength' and Greek andro- but with Vedic sū-nrt́ā 'good vigor, vitality' (used especially for Uṣás, thus gender ambivalent)". According to McKinnell, "The meaning of the name has usually been connected with Old Irish 'strength' (so 'the powerful one'), but it might be related to Old English 'contented' and neorxnawang 'paradise' (literally 'field of contentment'), or to the word 'north' (i.e. 'deity of the northern people', cf. Greek νέρτερος 'belonging to the underworld')".
Germania In chapter 40 of his ethnography Germania, Roman historian Tacitus, discussing the Suebian tribes of Germania, writes that, beside the populous Semnones and warlike Langobardi, there are seven more remote Suebian tribes; the Reudigni, Aviones, Anglii, Varini, Eudoses, Suarines, and Nuitones. The seven tribes are surrounded by rivers and forests and, according to Tacitus, there is nothing particularly worthy of comment about them as individuals, yet they are particularly distinguished as a group in that they all worship the goddess Nerthus. The chapter reads as follows: Latin: Contra Langobardos paucitas nobilitat: plurimis ac valentissimis nationibus cincti non per obsequium, sed proeliis ac periclitando tuti sunt. Reudigni deinde et Aviones et Anglii et Varini et Eudoses et Suardones et Nuithones fluminibus aut silvis muniuntur. Nec quicquam notabile in singulis, nisi quod in commune Nerthum, id est Terram matrem, colunt eamque intervenire rebus hominum, invehi populis arbitrantur. Est in insula Oceani castum nemus, dicatumque in eo vehiculum, veste contectum; attingere uni sacerdoti concessum. Is adesse penetrali deam intellegit vectamque bubus feminis multa cum veneratione prosequitur. Laeti tunc dies, festa loca, quaecumque adventu hospitioque dignatur. Non bella ineunt, non arma sumunt; clausum omne ferrum; pax et quies tunc tantum nota, tunc tantum amata, donec idem sacerdos satiatam conversatione mortalium deam templo reddat. Mox vehiculum et vestes et, si credere velis, numen ipsum secreto lacu abluitur. Servi ministrant, quos statim idem lacus haurit. Arcanus hinc terror sanctaque ignorantia, quid sit illud, quod tantum perituri vident.Stuart 1916:20.A. R. Birley translation: By contrast, the Langobardi are distinguished by being few in number. Surrounded by many mighty peoples they have protected themselves not by submissiveness but by battle and boldness. Next to them come the Ruedigni, Aviones, Anglii, Varini, Eudoses, Suarines, and Huitones, protected by river and forests. There is nothing especially noteworthy about these states individually, but they are distinguished by a common worship of Nerthus, that is, Mother Earth, and believes that she intervenes in human affairs and rides through their peoples. There is a sacred grove on an island in the Ocean, in which there is a consecrated chariot, draped with cloth, where the priest alone may touch. He perceives the presence of the goddess in the innermost shrine and with great reverence escorts her in her chariot, which is drawn by female cattle. There are days of rejoicing then and the countryside celebrates the festival, wherever she designs to visit and to accept hospitality. No one goes to war, no one takes up arms, all objects of iron are locked away, then and only then do they experience peace and quiet, only then do they prize them, until the goddess has had her fill of human society and the priest brings her back to her temple. Afterwards the chariot, the cloth, and, if one may believe it, the deity herself are washed in a hidden lake. The slaves who perform this office are immediately swallowed up in the same lake. Hence arises dread of the mysterious, and piety, which keeps them ignorant of what only those about to perish may see.Birley (1999:58).Harold Mattingly translation: The Langobardi, by contrast, are distinguished by the fewness of their numbers. Ringed round as they are by many mighty peoples, they find safety not in obsequiousness but in battle and its perils. After them come the Reudingi, Aviones, Anglii, Varini, Eudoses, Suarini and Nuitones, behind their ramparts of rivers and woods. There is nothing noteworthy about these peoples individually, but they are distinguished by a common worship of Nerthus, or Mother Earth. They believe that she interests herself in human affairs and rides among their peoples. In an island of the Ocean stands a sacred grove, and in the grove a consecrated cart, draped with cloth, which none but the priest may touch. The priest perceives the presence of the goddess in this holy of holies and attends her, in deepest reverence, as her cart is drawn by heifers. Then follow days of rejoicing and merry-making in every place that she designs to visit and be entertained. No one goes to war, no one takes up arms; every object of iron is locked away; then, and only then, are peace and quiet known and loved, until the priest again restores the goddess to her temple, when she has had her fill of human company. After that the cart, the cloth and, if you care to believe it, the goddess herself are washed clean in a secluded lake. This service is performed by slaves who are immediately afterwards drowned in the lake. Thus mystery begets terror and pious reluctance to ask what the sight can be that only those doomed to die may see.Mattingly 2009: 53-54.
Tacitus's sources Tacitus does not provide information regarding his sources for his description of Nerthus (nor the rest of Germania). Tacitus's account may stem from earlier but now lost literary works (such as perhaps Pliny the Elder's lost Bella Germaniae), potentially his own experiences in Germania, or merchants and soldiers, such as Germanic peoples in Rome, or Germania and Romans who spent time in the region.
Tacitus's Germania places particular emphasis on the Semnones, and scholars have suggested that some or all of Tacitus's information may come from King Masyas of the Semnones and/or his high priestess, the seeress Ganna. The two visited Rome for a blessing from Roman emperor Domitian in 92 AD. While Tacitus appears to have been away from Rome during this period, he would have had plenty of opportunity to gain information provided by King Masyas and Ganna from those who spent time with the two during their visit.
Reception Tacitus's description of the Nerthus procession has been the subject of extensive discussion from scholars.
Name and manuscript variations All surviving manuscripts of Tacitus's Germania date from around the fifteenth century and these display significant variation in the name of the goddess: All attested forms are in accusative case and include Nertum (yielding the nominate form Nerthus), Herthum (implying a nominative form of Hertha) and several others (including Nechtum, Neithum, Neherthum, and Verthum).For discussion on these forms, see for example Lindow 2020b: 1331 and McKinnell 2005: 50-52.
Of the various forms found in the extant Germania manuscript tradition, two have yielded significant discussion among scholars since at least the nineteenth century, Nerthus and Hertha. Hertha was popular in some of the earliest layers of Germania scholarship, such as the edition of Beatus Rhenanus. These scholars linked the name with a common German word for Earth (compare modern German Erde). This reading has subsequently been rejected by most scholars. Since pioneering nineteenth century philologist Jacob Grimm's identification of the form Nerthus as the etymological precursor to the Old Norse deity name Njǫrðr, the reading Nerthus has been widely accepted as correct in scholarship.
In 1902, the Codex Aesinas (often abbreviated as E) was discovered, and it was also found to contain the form Nertum, yielding the reading Nerthus. The Codex Aesinas is a fifteenth-century composite manuscript that is considered a direct copy of the Codex Hersfeldensis, the oldest identifiable manuscript of the text. All other manuscripts of Tacitus's Germania are thought by scholars to stem from the Codex Aesinas.
Some scholars have continued suggesting alternate readings to Nerthus. For example, in 1992, Lotte Motz proposes that the linguistic correspondence is a coincidence and that "The variant nertum was chosen by Grimm because it corresponds to Njǫrðr".
