High Quality Content by WIKIPEDIA articles! 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.
