However that may be, here is an instance which will give you an idea of the various readings of the Cid's history. Mariana relates, that an Arab expedition, headed by five kings (as he terms them) of the adjoining states, being signalized as having passed the mountains of Oca, and being occupied in committing depredations on the Christian territory, Rodrigo suddenly took the field, recovered all the booty, and made all five kings prisoners. All this being done by himself and his own retainers. The kings he released after signing a treaty, according to which they agreed to pay him an annual tribute. It happened, that on the occasion of the first payment of this, Rodrigo was at Zamora, whither he had accompanied the King of Castile; and he took an opportunity of receiving the Arab messengers in presence of the court. This was at least uncommon. The messengers addressed him by the appellation of Syd (sir) as they handed over the money. Ferdinand, delighted with the prowess of his courtier, expressed on this occasion the desire that he should retain the title of Syd. This anecdote undergoes, in the hands of the Arab writers, a curious metamorphosis. According to them, the expression Syd was employed, not by tributary kings, but by certain chiefs of that creed whose pay the Catholic hero was receiving in return for aid lent against the Christians of Aragon. They attribute, moreover, to this mirror of chivalry, on the surrender of Valencia, a conduct by no means heroic--not to say worthy a highwayman. He accepted, as they relate, the pay of the Emyr of Valencia to protect the city against the Almoravides, who at that period were extending their conquests all over Moorish Spain. The Cid was repulsed, and the town taken. After this defeat he shut himself up in a castle, since called the Peña del Cid (Rock of the Cid), and there waited his opportunity. On the departure of the conquerors from the city, in which they left an insufficient garrison, he hastened down at the head of his campeadores, and speedily retook Valencia. The Cadi, Ahmed ben Djahhaf, left in command of the place, had, however, only surrendered on faith of a capitulation couched in the most favourable terms. It was even stipulated that he should retain his post of governor; but no sooner was the Cid master of the place than he caused the old man to be arrested and put to the torture, in order to discover from him the situation of a treasure supposed to be concealed in the Alcazar; after which, finding he would not speak, or had nothing to reveal, he had him burned on the public place.
