Sinthgunt
Sinthgunt is a figure in Germanic mythology, attested solely in the Old High German 9th- or 10th-century Second Merseburg Charm. In the verse charm, Sinthgunt is referred to as the sister of the personified sun, Sunna, and the two sisters are cited as both producing incantations to heal the horse of Phol, another otherwise unattested figure but possibly the same as Balder, who is named elsewhere in the charm. The two are then followed by Friia and Uolla, also alliterative and stated as sisters.
As Sinthgunt is otherwise unattested, her significance is otherwise unknown, but some scholarly theories exist about her role in Germanic mythology based on proposed etymologies and the potential significance of her placement within the poem.
Etymology
The etymology of Sinthgunt is unclear. In the original manuscript, Sinthgunt is spelled Sinhtgunt. In the 19th century, Sophus Bugge stuck strictly to this reading, proposing a complex compound based on Germanic *Sin-naχt-gund, i.e., "the night-walking one". As a result of the pairing with Sunna, the personified sun, this etymology has been interpreted as a reference to the moon. However, this reading has yielded problems; the moon in Germanic mythology is considered masculine, exemplified in the personification of the moon in Norse mythology, Máni, a male figure. According to Rudolf Simek, the historical record lacks evidence for any cult of personified celestial bodies among the ancient Germanic peoples.Stefan Schaffner rejects this etymology, as does, because the first element Sinht- cannot be based on the presupposed earlier Germanic *sinχt-. Such a Germanic form would have yielded Old High German *sīht by regular sound change. The amended Sinthgunt presupposes a Proto-Germanic compound *Senþa-gunþjō, the first element meaning "raid, campaign", the second one "fight". This interpretation corresponds well to other Old High German female names such as Sindhilt. Simek also mentions the interpretation "heavenly body, star".
Placement
The figures Fulla and Frigg are attested together in later Old Norse sources, and theories have been proposed that Fulla may at one time have been an aspect of Frigg. This notion has resulted in a theory that a similar situation may have existed between the figures of Sinthgunt and Sunna/Sól, in that the two may have been understood as aspects of one another rather than entirely separate figures. Similarly, analysed her as a subordinate goddess from Sunna's retinue, a kind of "situation goddess", based on her unique appearance in the sources.Friedrich Kauffmann classified Sinhtgunt as a valkyrie in the 19th century, because the elements -gund and -hild appear frequently in their names. Stefan Schaffner and Heiner Eichner more recently agreed with him, based on Günter Müller's paper on the valkyries' healing powers.
Karl Helm rejected Kauffmann and grouped Sinhtgunt with the Idisi of the First Merseburg Charm, as a specially defined group of Germanic goddesses.
