Chapter 3 is a collection of Carlo Ginzburg's work that attempts to tie the account of Thiess to the cultic practices of the Benandanti in northeast Italy. He interprets the confession as an ecstatic spiritual ritual.

There are strong similarities, to be sure, but Lincoln is unconvinced and argues that the connections are being cobbled together from sources too disparate. Any similarities to the Benandanti could be a result of similar phenomenon rising independently in reaction to similar material forces in each region. Lincoln posits another theory in Chapter 4, arguing that Thiess is actually stealing cattle and taxed grain out of the Germanic overlords' storerooms and his confession to being a werewolf is an attempt to levy critiques and accusations back at the local powers. He's essentially trolling them by saying, "Yes, I'm a werewolf and I steal the grain from Satan for good purposes", implying that their taxation and rule is evil.

The two scholars respond to one another through correspondence and then have a more direct dialogue that eventually ends in an amicable aporia.

I'm more inclined to Lincoln's interpretation on this. His critiques of Ginzburg are rather thorough, and his argument that Thiess is visiting a real, physical space is compelling. He does however, underplay what I think is a ritualistic, shamanic, cultic component. Other villagers had attested that they knew he was werewolf and Thiess stated he wasn't the only one doing this. There's clearly some folkloric substratum here and it's almost as if cultural memories of the pastoral, marauding Indo-European koryos is bubbling up reformed in their distant descendants' settled, agrarian milieu.

I previously reviewed a novel by Hermann Lons, Der Wahrwolf, about a fictionalization of a German village that depredated soldiers in the 30 Years War. In that novel the local overlords were spared these attacks when they granted reprieves on taxes to these villagers. Curiously, Lons' work was published in 1910 before all this scholarship.
