04.[17] It was the first outburst of that hatred
in her heart which in the end was to destroy her for she died of a
poverty of love.

In 1005, still with her fleet engaged in Sicilian waters, the Arab
pirates fell upon her, and, forcing the harbour, sacked a whole quarter
of the city. For the time Pisa could do little against the foes of
Europe, but in 1016 she allied herself with that city which proved at
last to be her deadliest foe, Genoa the Proud, and the united fleets
swept down on Sardinia for vengeance. It was this victorious expedition
that aroused the hatred of the Pisans for Genoa, a jealousy that was
only extinguished when at last Pisa was crushed at Meloria.

Many were the attempts of the Arabs to regain Sardinia, but Pisa was not
to be deceived. Coasting along the African shore, her fleet took Bona
and threatened Carthage. Yet in 1050 the Arabs of Morocco and Spain
stole the island from her, only Cagliari holding out under the nobles
for the mother city. There was more than the loss of Sardinia at stake,
for with the victory of the Arabs the highway of the sea was no longer
secure, the existence of Pisa, and not of Pisa only, was threatened. So
we find Genoa once more standing beside Pisa in the fight of Europe. The
fleets again were combined, this time under the command of a Pisan, one
Gualduccio, a plebeian. He sailed for Cagliari, landed his men, and
engaged the enemy on the beach. The Arabs were led by the King Mogahid,
Re Musetto, as the Italians called him. He was over eighty years old at
the time, and though still full of cunning valour, attacked by the
fleets in front and the garrison in the rear, his army was defeated and
put to flight. He himself, fleeing on horseback, was wounded in two
places, and falling was captured; and they took him in chains to Pisa,
where he died. Thus Sardinia once more fell into the hands of Europe,
and the island, divided in fiefs under the rule of Pisa,[18] was held
and governed by her.

But Pisa was not yet done with the Arab. She stood for Europe. In 1063
she fought at Palermo, returning laden with booty. It was then, after
much discussion in the Senate,[19] sending an embassy to the Pope and
another to "Re Henrico di Germania," that she decided to employ this
spoil in building the Duomo, in the place where the old Church of S.
Reparata stood, and more anciently the Baths of Hadrian, the Emperor.
The temple, Tronci tells us,[20] was dedicated to the Magnificent Qu
