This is the drawing of the Sami ceremonial drum found in the Naerøy Manuscript, attributed to Thomas von Wessen, 1723. It is in the public domain, and there are other versions of it that render more detail.
Johan Randulf, the author of the Naeroy manuscript, rambles a lot, sermonizing about the practices of the Sami and sometimes about completely unrelated topics. Distilling the first few pages, he makes it clear that the figure on the top center of the ceremonial drum is indeed Thor. He states that the Sami would invoke Thor to hold back thunder and lightning to protect their reindeer, but would also invoke Thor to bring thunder and lightning to bring fire upon their enemies.
The Naerøy Manuscript asserts that the Thor is the equivalent of the Greek god Jupiter. Recent scholarship would refute any connection between the Greek gods and the Norse gods, except for some similarities between the Norse god Tyr and the Greek god Zeus. According to Dr. Jackson Crawford, the Norse god Thor bears some resemblance to a Slavic god and an Indian god, but none to the Greeks. (https://www.youtube.com/watch?v=z_gkGBF6zgA).
Randulf also mentions Thursday, or Thor’s Day, as a sort of sabbath for the Sami.
Peasants have a custom of crossing knives over their jugs of beer before they drink it, and etching a cross over a cask of butter before they close the lid. If they are Sami, the cross indicates the two hammers of Thor. Snorle Stulesen’s Norwegian Chronicle is mentioned as a source.
