SURREY is represented hastening on a chivalric expedition to Italy; at Florence he challenges the universe, that his Geraldine was the peerless of the beautiful. In his travels, Cornelius Agrippa exhibited to Surrey, in a magical mirror, his fair mistress as she was occupied at the moment of inspection. He beheld her sick, weeping in bed, reading his poems, in all the grief of absence. This incident set spurs to his horse. At Florence he hastened to view the chamber which had witnessed the birth of so much beauty. At the court he affixed his challenge, and maintained this emprise in tilt and tourney. The Duke of Florence, flattered that a Florentine lady should be renowned by the prowess of an English nobleman, invited Surrey to a residence at his court. But our Amadis more nobly purposed to hold on his career through all the courts of Italy, shivering the lances of whoever would enter the lists, whether "Christian, Jew, or Saracen." Suddenly the Quixotism ends, by this paragon of chivalry being recalled home by the royal command. This Italian adventure seemed congenial with the romantic mystery in which the poet had involved the progress of his passion for his poetic mistress. He had himself let us into some secrets. Geraldine came from "Tuscany;" Florence was her ancient seat, her sire was an earl, her dame of "princes' blood," "yet she was fostered by milk of an Irish breast;" and from her tender years in Britain "she tasted costly food with a king's child." The amatorial poet even designates the spots hallowed by his passion; he first saw her at Hunsdon, Windsor chased him from her sight, and at Hampton Court "first wished her for mine!" These hints and these localities were sufficient to irritate the vague curiosity of Surrey's readers, and more particularly of our critical researchers, of whom Horace Walpole first ventured to explain the inexplicable. With singular good fortune, and from slight grounds, Walpole conjectured that Geraldine was no Italian dame, but Lady Elizabeth Fitzgerald, one of the daughters of the Earl of Kildare; the family were often called the Geraldines. The Italian descent from the Geraldi was made out by a spurious genealogy. The challenge and the tournament no one doubted. But some harder knots were to be untied; and our theoretical historian, unfurnished by facts and dates, it has been recently shown, discovered some things which never existed.
