Depicting Jews as dog-men reinforced the parallel trope of Muslims as Christ-killers

Evidence

The existence of Jewish cynocephalie in texts has been described by Kathleen Corrigan: “In the illustrations of both Psalm 21 and Psalm 68:22 the artists have taken great care to emphasize the wickedness of the Jews. The Jews are caricatured, labeled as dogs, and depicted as dog-headed men.” This image of Jewish cynocephalie as Christ-killers reinforces a common medieval trope about both Jews and Muslims as the executioners of Christ, because the existence of one, as I have argued earlier, conjured up the appearance of the other. — Sophia Rose Arjana, Muslims in the Western Imagination, 220

Categorization

• XREF: The claim that depicting one out-group conjured the other mechanistically connects to the reader’s core thesis that the monster-image manufactures itself, and to similar contagion-of-stereotype dynamics seen in anti-Semitic and anti-Muslim visual propaganda studied elsewhere.
• SEED: A comparative essay could trace how Catholic visual rhetoric used one demonized group to legitimize stereotyping the other, and how that reciprocal reinforcement persists in modern conflations (e.g., equating Muslims with pre-existing European anti-Semitic tropes).
