The original copy of "Gerusalemme Liberata," in the handwriting of Tasso, is in the Soane Museum. It was purchased by Sir John Soane, at the sale of the Earl of Guilford's Library, in 1829. This literary treasure, which cannot be contemplated without emotion, once belonged to Baruffaldi, one of the most eminent literary characters of modern Italy. Serassi describes it, and refers to the emendations made by the poet in the margin (Serassi's edit. Florence, 1724;) but expresses his fear that it had been taken out of Italy. In allusion to this expression of Serassi, Lord Guilford has written on the fly-leaf of the MS., "I would not wish to hurt the honest pride of any Italian; but the works of a great genius are the property of all ages and all countries: and I hope it will be recorded to future ages, that England possesses the original MS. of one of the four greatest epic poems the world has produced, and, beyond all doubt, the only one of the four now existing." There is no date to this MS. The first printed edition of the Gerusalemme is dated 1580.

There are other rare and valuable MSS. in this Museum, the most remarkable of which are a Commentary in Latin on the epistle of St. Paul to the Romans, by Cardinal Grimani. It is adorned with exquisite miniature illustrations, painted by Don Giulio Clovio, called the Michael Angelo of miniature painters. "The figures are about an inch in height," says Mrs. Jameson, "equaling in vigor, grandeur, and originality, the conceptions of Michael Angelo and of Raffaelle, who were his cotemporaries and admirers." Also, a missal of the fifteenth century, containing ninety-two miniatures by Lucas van Leyden and his scholars, executed in a truly Dutch style, just the reverse of those of Clovio, except in point of elaborate finishing.
