the injury could not be tolerated without disgrace, and that the
only vengeance proportionate to the enormity of the offence would be to
put Buondelmonti to death. And although some took into consideration the
evils that might ensue upon it, Mosca Lamberti said, that those who talk
of many things effect nothing, using that trite and common adage, _Cosa
fatta capo ha_. Thereupon, they appointed to the execution of the murder
Mosca himself, Stiatti Uberti, Lambertuccio Amidei, and Oderigo Fifanti,
who, on the morning of Easter day, concealed themselves in a house of
the Amidei, situate between the old bridge and St. Stephen's, and as
Buondelmonti was passing upon a white horse, thinking it as easy a
matter to forget an injury as reject an alliance, he was attacked by
them at the foot of the bridge, and slain close by a statue of Mars.
This murder divided the whole city; one party espousing the cause of
the Buondelmonti, the other that of the Uberti; and as these families
possessed men and means of defense, they contended with each other for
many years, without one being able to destroy the other.

Florence continued in these troubles till the time of Frederick II.,
who, being king of Naples, endeavored to strengthen himself against the
church; and, to give greater stability to his power in Tuscany, favored

with each faction. Those who adopted the cause of the Guelphs were
the Buondelmonti, Nerli, Rossi, Frescobaldi, Mozzi, Bardi, Pulci,
Gherardini, Foraboschi, Bagnesi, Guidalotti, Sacchetti, Manieri,

Vecchietti, Tosinghi, Arrigucci, Agli, Sizi, Adimari, Visdomini, Donati,

faction were the Uberti, Manelli, Ubriachi, Fifanti, Amidei, Infangati,

enumerated, each party was joined by many o
