Another event, likewise occurring in the years 1113-15, although dated by the chroniclers in 1117, namely, the Pisan expedition to the Balearic Isles, also led to a somewhat complicated dispute. As already related, the Pisans began to make war on the Mussulmans from the middle of the tenth century, and during the latter half of the next century the strife was pursued more hotly than ever. In 1087 Pisa and Genoa combined, displayed a fleet of forty sail in battle array before Mehdia, and in 1113 both cities joined in the more important expedition to the Balearic Isles. They were also accompanied by many counts and marquises from Lombardy and Central Italy, likewise including a few from the Florentine territory. Then, combining with the Counts of Barcelona and Montpellier, the Viscount of Narbonne, and others, they attacked the Balearic Isles, and, in spite of a very obstinate resistance, seized the castle of Majorca, and captured young Burabe, the last scion of the ruling dynasty there. Villani, in alluding to this war of 1113-15, assigns it, like the other chroniclers, to the year 1117, adding that the Pisans fearing, when about to set sail, that the Lucchese might, as once before, take advantage of their absence to attack their city, entrusted the Florentines with its defence. The latter immediately encamped two miles from the walls and forbade their men to enter Pisa, under penalty of death; for, seeing that scarcely any males were left in the city, they feared some attempts might be made on the honour of its women, to the grave discredit of Florentine loyalty. And this decree was rigorously enforced. One soldier who dared to violate the rules of discipline was condemned to death, notwithstanding the prayers of the Pisans, who, as the only chance of saving the man's life, protested that they could not permit a capital sentence to be executed on their territory. Whereupon the Florentines, showing even in this matter their scrupulous regard for others' rights, purchased a scrap of land, and there put the culprit to death. Meanwhile, the Pisans returning from Majorca, laden with spoil, offered in token of gratitude to their faithful friends the choice of accepting either two bronze doors or two porphyry columns. The Florentines preferred the latter. The columns were consigned to them wrapped in scarlet cloth, in token of their value, and now stand in the chief portal of San Giovanni. However, when the cloth was stripped off, it was seen that some envious person had injured the columns with fire. Evidently part of this account is legendary, and we also discern that something must have been added to it afterwards, when Pisa and Florence were separated by long and inextinguishable animosity.[110]
