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.
