Leonbruno, Lorenzo, an Italian painter, was born at Mantua in 1489; studied under count Castiglione, the friend of Raphael; appointed painter to the duke of Mantua; gave offense to Giulio Romano, in consequence of which he was obliged to quit Mantua; settled at Milan, and died there about 1537. Three of his pictures at Mantua are very highly praised, viz., St. Jerome: — The Metamorphosis of Midas: — and The Body of Christ in the Arms of the Virgin. See Spooner, Biog. Hist. of Fine Arts, s.v.
