Mongolian Report at Second Council of Lyon

Brewer (p. 279) mentions this document, "apparently penned by the Mongol ambassadors who were present at the Second Council of Lyon in 1274, which alleges that their ' first lady' (domina principalis), Toquz Khatun, was a 'most Christian queen' (regina christianissima) and a 'daughter of the most powerful King John of India' (filia potentissimi regis Indie Iohannes)."
