RefutedSolid, positive evidence shows it is false.
This is false. The accusation appears in 1235 at Fulda — it is absent from the Norwich narrative — and it contradicts the ban on blood at the heart of Jewish dietary law. It was rejected by an imperial inquiry (1236) and by the pope (1247).
Assessment
Evidence for
- +Confessions to this effect were obtained, notably at Trent — under torture.
Evidence against
- −The Hebrew Bible and Jewish law forbid consuming blood (Leviticus 17:10–14).
- −Frederick II's inquiry (1236): no Jewish rite requires blood.
- −Innocent IV's letter (1247) condemning these accusations.
- −The blood motif is absent from the first narrative (Norwich): it appears nearly a century later.
Limits of the sources
None
Reasoning
Several positive and independent elements contradict the claim: an explicit religious norm, two medieval inquiries, and the history of the accusation itself, which shows that this motif was added later.
