to have been raised in Thrace by a chieftain named Lorikus, whom he later slew to assume the title of "King of Thrace", to have had hair "fairer than gold", and to have been strong enough to lift ten bearskins.

The saga narrative adds that numerous names—at the time of the narrative, popularly in use—were derived from Thor. Saint Olaf Around the 12th century, folk traditions and iconography of the Christianizing king Olaf II of Norway (Saint Olaf; c. 995 – 1030) absorbed elements of both Thor and Freyr. After Olaf's death, his cult had spread quickly all over Scandinavia, where many churches were dedicated to him, as well as to other parts of Northern Europe. His cult distinctively mixed both ecclesiastical and folk elements. From Thor, he inherited the quick temper, physical strength and merits as a giant-slayer. Early depictions portray Olaf as clean-shaven, but after 1200 he appears with a red beard. For centuries, Olaf figured in folk traditions as a slayer of trolls and giants, and as a protector against malicious forces. Modern folklore Tales about Thor, or influenced by native traditions regarding Thor, continued into the modern period, particularly in Scandinavia. Writing in the 19th century, scholar Jacob Grimm records various phrases surviving into Germanic languages that refer to the god, such as the Norwegian ("Thor's warmth") for lightning and the Swedish ("The good old (fellow) is taking a ride") as well as the word ("Thor's rumble" or "Thor's thunder") when it thunders.
