Surely, in the whole domain of history, no object has a grander symbolism than the key. In mediæval times the keys of cities, castles, towns, and fortresses were held to be significant of ownership, or vigilance, or conquest. Especially was this the case in Spain--a nation incessantly engaged in war. Probably in no country in the world has the ceremony of delivering up this mark of tenure of a guarded and defended place occurred so often as here. Do we not read of it in stirring stanzas of her literature? Do we not find it in her paintings, on her stone and metal _rilievi_, or carved in wood upon the stalls of her cathedrals? Therefore the key, just like the sword, seemed, in the warm imagination of the Spaniards, to be something almost sacred. The legislative codes of Old Castile are most minute in their relation of its venerated attributes. Nor were the Spanish Muslims less alive to its importance than their foe, taking it also for an emblem of their own, and planting it in lordly eminence upon their gates and towers of Cordova, and Seville, and Granada. For what was Tarik's Mountain but the key of the narrow gate that led to their enchanted land, as sunny as, and yet less sultry than, their sandy home; truly a land of promise to the fiery children of the desert, panting for the paradise that smiled at them across the storied strip of emerald and sapphire water? So was it that both Moors and Spaniards made their keys of fortresses and citadels almost into an object of their worship. In hearing or in reading of such keys, the mind at once recurs to those of Seville (Plate xix.), two in number, famed throughout the world of mediæval art, and stored among the holiest relics in the sacristy of her cathedral. The larger is of silver, in the style now known as Mudejar, and dates from the second half of the thirteenth century. The length is rather more than eight inches, and the whole key is divided into five compartments, ornamented in enamels and in gold. Castles, ships, and lions adorn the thicker portion of the stem between the barrel proper and the handle; and on the rim of the latter is this inscription, in Hebrew characters:-- "_The King of Kings will open; the king of all the land shall enter._"[62] [62] Riaño's reading was, "_the King of the whole Earth will enter_." But is not this contradicted by the other inscription on the same key? The wards are also beautifully carved into the following legend, distributed in two rows, one superposed upon the other, of two words and of ten letters apiece:-- "_Dios abrirá; Rey entrará._" "_God will open; the king shall enter._" The iron key is purely Moorish, smaller than its fellow, and measures just over six inches. Like the other, it consists of five divisions, and the wards are in the form of an inscription in African Cufic characters, which Gayangos and other Arabists have variously interpreted. Five of the commonest readings are as follows:--
