Donar's oak

Jove's Oak (interpretatio romana for Donar's Oak and therefore sometimes referred to as Thor's Oak) was a sacred tree of the Germanic pagans located in an unclear location around what is now the region of Hesse, Germany. According to the 8th century Vita Bonifatii auctore Willibaldi, the Anglo-Saxon missionary Saint Boniface and his retinue cut down the tree earlier the same century. Wood from the oak was then reportedly used to build a church at the site dedicated to Saint Peter. Sacred trees and sacred groves were widely venerated by the Germanic peoples and scholars have linked this oak and others to the world tree in Norse mythology, Yggdrasil.

According to Willibald's 8th century Life of Saint Boniface, the felling of the tree occurred during Boniface's life earlier the same century at a location at the time known as Gaesmere (for details, see discussion below).

Although no date is provided, the felling may have occurred around 723 or 724. Willibald's account is as follows (note that Robinson has translated robor Iobis, "tree of Jove", as "Tree of Jupiter"):

Cum vero Hessorum iam multi, catholica fide subditi ac septiformis spiritus gratia confirmati, manus inspositionem acciperunt, et quidem, nondum animo confortati, intermeratae fidei documenta integre perceipere rennuerunt, alii etiam lignis et fontibus clanculo, alii autem aperte sacrificabant; alii vero aruspicia et divinationes, prestigia atque icantationes occulte, alii quidem manifeste exercebant; alii quippe auguria et auspicia intendebant diversosque sacrificandi ritus incoluerunt; alii etiam, quibus mens sanior inerat, omni abeicta gentilitatis profantione, nihil horum commisserunt. Quorum consultu atque consilio roborem quendam mirae magnitudinis, qui prisco paganorum vocabulo appellatur robor Iobis, in loco qui dicitur Gaesmere, servis Dei secum adstantibus succidere temptavit. Cumque, mentis constantia confortatus, arborem succidisset, — magna quippe aderat copia paganorum, qui et inimicum deorum suorum intra se diligentissime devotabant,—sed ad mdoicum quidem arbore praeciso, confestim immensa roboris moles, divino desuper flatu exagitata, palmitum confracto culmine, corruit et quasi superni nutus solatio in quattuor etiam partes disrupta est, et quattor ingentis magnitudinis aequali longitudine trunci absque fratrum labore adstantium apparuerunt. Quo viso, prios devotantes pagani etiam versa vice benedictionem Domino, pristina abiecta maledictione, credentes reddiderunt. Tunc autem summae sanctitatis antistes, consilio inito cum fratribus, ligneum ex supradictae arboris metallo oratorium construxit eamque in honore sancti Petri apostoli dedicavit.
