,--veritable enchanted bowers of
Oriental gardens,--he had led the life both of pagan and savant,
surrounded by poets and men of science (Jews, Mahometans and
Christians), by Oriental dancers, alchemists, and ferocious Saracen
Guards. He legislated as did the jurisconsults of ancient Rome, at the
same time writing the first verses in Italian. His life was one
continual combat with the Popes who hurled upon him excommunication
upon excommunication. For the sake of peace he had become a crusader
and set forth upon the conquest of Jerusalem. But Saladin, another
philosopher of the same class, had soon come to an agreement with his
Christian colleague. The position of a little city surrounded with
untilled land and an empty sepulcher was really not worth the trouble
of decapitating mankind through the centuries. The Saracen monarch,
therefore, graciously delivered Jerusalem over to him, and the Pope
again excommunicated Frederick for having conquered the Holy Land
without bloodshed.

"He was a great man," Don Esteban used to murmur. "It must be admitted
that he was a great man...."

He would say this timidly, regretting that his enthusiasm for that
remote epoch should oblige him to make this concession to an enemy of
the Church. He shuddered to think of those sacrilegious books that
nobody had seen, but whose paternity Rome was accustomed to attribute

the same standard. This royal author was, moreover, the most ancient
journalist of history, the first that in the full thirteenth century
had dared to appeal to the judgment of public opinion in his
manifestoes against Rome.

His daughter had married an Emperor of Byzantium, Juan Dukas Vatatzes,
the famous "Vatacio," when he was fifty and she fourteen. She was a
natural daughter soon legitimized like almost all his progeny,--a
product of his free harem, in which were mingled Saracen beauties and
Italian marchionesses. And the poor young girl married to "Vatacio the
heretic," by a father in need of political alliances had lived long
years in the Orient as a _basilisa_ or empress, arrayed in garments of
stiff embroidery representing scenes from the holy books, shod with
buskins laced with purple which bore on their soles eagles of
gold,--the highest symbol of the majesty of Rome.

At first she had reigned in Nicaea, refuge of the Greek E
