_Giovanni Oriolo_ (Ferrarese: painted about 1450).
Of Oriolo nothing is known. He was probably by birth a
Ferrarese, and was evidently a pupil of Pisano (see 776).
Leonello (of whom also there is a medallion portrait in the frame of
the picture just referred to), of the house of Este, was Marquis of
Ferrara, 1441-1450. His mild and kindly face agrees well with what is
known of his life. The one important action of his reign was that of a
peacemaker, when he mediated between Venice and the King of Anjou. "He
had not his equal," says Muratori, "in piety towards God, in equity and
kindness towards his subjects. He was the protector of men of letters
and was himself a good Latin scholar."
