Now while the damsel, mourned at home as lost and dead, dwelt thus at Susa, it so befell that, Mariabdela being then King of Tunis, a young chieftain in Granada, of great power, and backed by mighty allies, gave out that the realm of Tunis belonged to him, and having gathered a vast army, made a descent upon Tunis with intent to expel the King from the realm.  Martuccio Gomito, who knew the language of Barbary well, heard the tidings in prison, and learning that the King of Tunis was mustering a mighty host for the defence of his kingdom, said to one of the warders that were in charge of him and his comrades:—­“If I might have speech of the King, I am confident that the advice that I should give him would secure him the victory.”  The warder repeated these words to his chief, who forthwith carried them to the King.  Wherefore by the King’s command Martuccio was brought before him, and being asked by him what the advice, of which he had spoken, might be, answered on this wise:—­“Sire, if in old days, when I was wont to visit this country of yours, I duly observed the manner in which you order your battle, methinks you place your main reliance upon archers; and therefore, if you could contrive that your enemy’s supply of arrows should give out and your own continue plentiful, I apprehend that you would win the battle.”  “Ay indeed,” replied the King, “I make no doubt that, could I but accomplish that, I should conquer.”  “Nay but, Sire,” returned Martuccio, “you may do it, if you will.  Listen, and I will tell you how.  You must fit the bows of your archers with strings much finer than those that are in common use, and match them with arrows, the notches of which will not admit any but these fine strings; and this you must do so secretly that your enemy may not know it, else he will find means to be even with you.  Which counsel I give you for the following reason:—­When your and your enemy’s archers have expended all their arrows, you wot that the enemy will fall to picking up the arrows that your men have shot during the battle, and your men will do the like by the enemy’s arrows; but the enemy will not be able to make use of your men’s arrows, by reason that their fine notches will not suffice to admit the stout strings, whereas your men will be in the contrary case in regard of the enemy’s arrows, for the fine string will very well receive the large-notched arrow, and so your men will have an abundant supply of arrows, while the enemy will be at a loss for them.”

The King, who lacked not sagacity, appreciated Martuccio’s advice, and gave full effect to it; whereby he came out of the war a conqueror, and Martuccio, being raised to the chief place in his favour, waxed rich and powerful.  Which matters being bruited throughout the country, it came to the ears of Gostanza that Martuccio Gomito, whom she had long supposed to be dead, was alive; whereby her love for him, some embers of which still lurked in her heart, burst forth again in sudden flame,
