Wow I couldn't believe how much it seemed that Wolfe was having Severian question Eata so specifically in Urth of the New Sun about his past to the point where The Map couldn't have happened. Discrepancies in the severity and number of beatings administered to Eata, in when Severian was autarch and when Valeria was in power, and in Severian's capital punishment policy.
Is "the Map" from a different iteration of Severian, who never leaves Urth? There are more inconsistencies between the map and shadow of the torturer than there are between shadow and urth of the new sun ... Weird.
