What is "sinthgunt"

Sinthgunt is a figure in Germanic mythology, attested solely in the Old High German 9th- or 10th-century "horse cure" Merseburg Incantation. In the incantation, Sinthgunt is referred to as the sister of the personified sun, Sunna (whose name is alliterative to Sinthgunt), and the two sisters are cited as both producing charms to heal Phol's horse, a figure also otherwise unattested. 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 incantation.
