a ruler than as a man of learning. He was indeed the
only monarch of our age who was, at the same time, the friend of
learning and of virtue, and I trusted that he might correct such things
as he found to criticise in my work." Having learned the reason of the
great poet's visit, King Robert fixed a day for the consideration of
Petrarch's work; but, after a discussion which lasted from noon until
evening, it was found that more time would be necessary on account of
the many matters which came up, and so the two following days were
passed in the same manner. Then, at last, Petrarch was pronounced worthy
of the honor which had been offered him, and there was much feasting at
the palace that night, and much song, and much music, and much wine was
spilled.

Not the least attentive listener in those three days of discussion and
argument was the Princess Joanna, the granddaughter of the king, his
ward and future heir. For in the midst of his life of agreeable
employment, _Il buon Re Roberto_ had been suddenly called upon to mourn
the loss of his only son, Robert, Duke of Calabria, who had been as
remarkable for his accomplishments--according to the writers of
chronicles--as for his goodness and love of justice. Two daughters
survived him, Joanna and Maria, and they were left to the care of the
grandfather, who transferred to them all the affection he had felt for
the son. In 1331, when Joanna was about four years old, the king
declared her the heiress of his crown; and at a solemn feudal gathering
in the great audience room of the castle Nuovo, he called upon his
nobles and barons to take oaths of allegiance to her as the Duchess of
Calabria; and this they did, solemnly and in turn, each bending the knee
in token of submission. With the title of Duchess of Calabria, she was
to inherit all her father's right to the thrones of Naples and
Provence.

As soon as she came under his guardianship, the education of the small
Joanna became the constant preoccupation of her kindly grandfather, for
he was filled with enthusiasm for the manifold advantages of learning,
and spared no pains to surround the little duchess with the best
preceptors in art and in literature that Italy afforded. All
contemporary writers agree that the young girl gave quick and ready
response to these influences, and she soon proved her possession of most
unusual talents, combined with a great love for literary study; it is
said that, at the age of twelve, she
