Orientalism treated Jews and Muslims as joint subjects from its medieval beginnings.

Evidence

Kalmar’s seminal work on Orientalism demonstrated that both Jews and Muslims were joint subjects from the discourse’s medieval beginnings. In addition, he has shown the importance in Orientalism of the foundational Christian notion of connected Jewish and Muslim understandings of God as unforgiving and despotic. — James Renton, Ben Gidley (eds.), Antisemitism and Islamophobia in Europe, 83

Categorization

• XREF: Directly engages Said’s Orientalism, which I’ve read — extends the thesis to argue Jews and Muslims were co-constituted as one Oriental subject, and roots it in a specifically Christian theological notion.
• ADDENDUM: Supports the ‘Complaints About Immodesty Go Way Back’ article’s wider argument that so-called secular or modern discourse inherits older religious framings of the Other.
