The Conde de Valencia de San Juan endeavours to prove--and, I think, with success--that the sword numbered G21, believed at one time to be the Cid’s famous blade “Colada,” is no other than the “Lobera” of St. Ferdinand. How the name “Lobera” came to be applied to a sword is unknown. The Conde hazards a conjecture that it was named after a gentleman called Guillen Lobera, who is referred to in the memoirs of Jaime I. of Aragon. The word was first used in this connection by the Saint himself, who, on his death-bed, bequeathed to the Infante Manuel for all his inheritance, “his Lobera sword, which was of great virtue, and by means of which God had greatly helped him.” Not less interesting is the passage in the chronicle of Alfonso XI., referring to the famous battle of Salado: “Then the King sent word to Don Juan, son of the Infante Manuel (grandson of Ferdinand), by a gentleman, to ask why he and those in the front did not pass the river. And an esquire, called Garci Jofre Tenoryo, son of the Admiral killed by the Moors, who was a vassal of the King and in the front, said to Don Juan, that his Lobera sword, which he said had virtue, would do the most work that day.” The blade (see plate 4) is smooth, double-edged, and round-pointed; on both sides for two-thirds of its length it is grooved, like most swords of that time. Inside both grooves are certain signs or letters, engraved and gilded, which the Conde de Valencia reads as the words--_Si_, _si_, _No_, _non_. This somewhat cryptic inscription, the learned antiquary explains as being part of the motto of St. Ferdinand, which may be roughly translated--“Let your yea be yea, and your nay be nay.” The hilt is of the sixteenth century, and was the work of Salvador de Avila, a swordmaker of Toledo, who died in 1539. Next to this sword is another of the same era (G22), erroneously attributed to Roland, the famed Paladin of the eighth century. It is not impossible that this also was one of St. Ferdinand’s weapons. It is very long and broad, thin and flexible, double-edged, scallop-pointed, and grooved for two-thirds of its length. The groove is engraved with rings or circles, and ends in an elaborate cruciform device. The guard, of massive silver-gilt, has quillons drooping and curving inward, and bears the arms of Castile on one side and those of Leon on the other. The hilt is of wood, plated with silver; the pommel is of iron, and is plated with silver-gilt. The plates were once covered with filigree work. The scabbard is of wood, sheathed in silver-gilt plate, and covered with lace-work, essentially Morisco in character. Of the seventy-five stones originally set in this filigree, only the half remain, including a large amethyst and three engraved stones of the classical style and period (plate 5).
