Note 6 — APPENDIX I THE GREAT MOSQUE OF CORDOVA

Foseyfasa.—Gayangos tells us that the word is not in the dictionaries, but that, according to an old Arabian writer, it is a substance of glass and small pebbles crushed and baked together, uniting, with great variety of colour, great brilliancy and beauty; it is sometimes mixed with silver and gold. One of the conditions of peace granted to the Emperor of Constantinople by the Khalif Al-walid was that the Emperor should provide a certain quantity of foseyfasa or enamelled work for the great Mosque at Damascus. Idrísí, in his description of the Mosque of Cordova, says that the enamel which covered the walls of the mih-rab came from Constantinople.
