Asturian chroniclers identified contemporary Muslims with biblical Ishmael as divine enemies

Evidence

The Prophetic Chronicle opens with a prophecy based very loosely on Ezekiel 38–39. Ezekiel had predicted battles between Gog and Israel; the anonymous chronicler associates Gog with the Goths (as Isidore and others had done before him) and changes “Israel” into “Ishmael.” — John V. Tolan, Saracens, 557

Categorization

• XREF: The direct substitution of ‘Israel’ with ‘Ishmael’ — biblical genealogy weaponized to define Muslims as hereditary enemies — is the genealogical seed of the Abrahamic-brother-enemy trope examined in Anidjar and vault claims about Islam as Christianity’s internal twin.
• QUESTION: Worth chasing: the Gog=Ishmael substitution reverses Ezekiel entirely (Israel becomes the enemy?) — which side do the Asturians read as ‘Israel’ then?
