Donar- Germanic GodDeity"The Thunderer"

The Name on the Brooch

No continental narrative myths of Donar survive. What survives is his name, carved and spoken in places that prove how deeply he mattered. The Nordendorf I fibula, a sixth- or seventh-century brooch found near Augsburg in Bavaria, bears a runic inscription: logaþore wodan wigiþonar. The final word likely means "consecrating Þonar" or "battle-Þonar." It is one of the few continental Germanic texts that name the thunder god directly, and it places him alongside Wodan on a single small object, the two gods paired as they are in the weekday names and the baptismal vow.

His name means "thunder." Nothing more, nothing less. The storm itself, given a will and a hammer.

The Columns Along the Rhine

Across the Rhineland and neighboring provinces, over 150 stone columns from the second and third centuries depict a mounted figure trampling a giant or a creature with serpent legs. Roman soldiers and Romanized Germans raised these Jupitergigantensäulen, Jupiter Giant columns, but the iconography has no parallel in Roman Jupiter worship. The horseman crushing the chaos-creature below him belongs to the Germanic thunder god, dressed in Jupiter's name for a Roman audience.

The columns cluster in the provinces of Germania Superior and Inferior. Their concentration along the Rhine frontier marks the boundary where Roman and Germanic religious traditions met and merged. Whatever prayers were spoken at their bases were addressed to Donar in all but name.

The Oak at Geismar

Donar's cult centered on sacred oaks. The tallest trees in the forest drew lightning, and the lightning belonged to the thunder god. Sacred oaks served as worship sites across the Germanic lands, and the most famous stood at Geismar in Hesse.

In 723 CE, the Christian missionary Boniface went to Geismar with an axe. According to Willibald's Vita Bonifatii, a crowd of pagan Hessians gathered to watch, expecting the thunder god to strike down the blasphemer. Boniface began chopping. No bolt came. A sudden wind caught the great oak and toppled it, splitting it into four pieces. The Hessians stared. Many converted on the spot. Boniface had the wood carried off and built a chapel to St. Peter.

The Indiculus superstitionum, an eighth-century Frankish document, condemns worship at trees and groves in terms that suggest Geismar was not unique. Sacred oaks likely stood across the Germanic world. Boniface chose the one that would make the loudest point.

The Vow

When Saxon converts accepted baptism, they spoke a formula preserved in a Vatican manuscript: "I forsake Thunaer and Woden and Saxnote and all the demons who are their companions." Thunaer comes first. The missionaries knew which god held the common people, and they named him before all others.

Charlemagne's Capitulatio de partibus Saxoniae of 785 imposed severe penalties on Saxons who continued to worship at sacred groves and make offerings to the old gods. The prohibitions were repeated, which means they were not obeyed. Meanwhile, at Trendgården in Denmark, a soapstone mold was carved that could cast both hammer pendants and cross pendants from the same block. For a time, at least, some people wore both.
