Sacra Congregatio Eminentissimorum ac RR. DD. S. R. E. Cardinalium negotiis propagandae fidei praepositorum.
8vo. 37, (1) pp., final blank leaf. Sewn without binding.
Extremely rare publication of the rules of the Coptic Catholic Church, decreed in 1790 and printed in Latin and Arabic in Rome in 1830, following the Ottomans' permission that the Coptic Catholics of Egypt build their own churches: "In conventu habito die 15 Martii anni 1790 decrevit, infrascriptas regulas ab omnibus RR. Sacerdotibus tam saecularibus, quam regularibus ritus Coptici, vel in urbe Cayri, vel in superiori Aegypto commorantibus, esse observandas".
Paper flaws to second leaf, with minor loss to a few letters. No other copy could be traced in libraries internationally.
