In Elizabeth's time, the forms and sentiment of chivalry were kept up by an effort. The parts enacted by Sidney and Raleigh, appear studied rather than instinctive. At all events, the gallant Sir Philip was the last of English knights, as he was the first of his time. Thenceforward, the valour of the country assumed a character more professional. But a fact thus familiar to us of England, is more remarkable of the rest of Europe. The infallibility of Rome once assailed, every faith was shaken. Loyalty was lessened, chivalry became extinct; expiring in France with Henri IV. and the League--in Portugal with Don Sebastian of Braganza--and in Spain with Charles V., exterminated root and branch by the pen of Cervantes. One of the most brilliant effervescences, however, of those crumbling institutions, is connected with Spanish history, in the person of Don John of Austria;--a prince who, if consecrated by legitimacy to the annals of the throne, would have glorified the historical page by a thousand heroic incidents. But the sacrament of his baptism being unhappily unpreceded by that of a marriage, he has bequeathed us one of those anomalous existences--one of those incomplete destinies, which embitter our admiration with disappointment and regret. On both sides of royal blood, Don John was born with qualifications to adorn a throne. It is true that when his infant son was entrusted by Charles V. to the charge of the master of his household, Don Quexada, the emperor simply described him as the offspring of a lady of Ratisbon, named Barbara Blomberg. But the Infanta Clara Eugenia was confidentially informed by her father Philip II., and confidentially informed her satellite La Cuea, that her uncle was "every way of imperial lineage;" and but that he was the offspring of a crime, Don John had doubtless been seated on one of those thrones to which his legitimate brother Philip imparted so little distinction. Forced by the will of Charles V. to recognize the consanguinity of Don John, and treat him with brotherly regard, one of the objects of the hateful life of the father of Don Carlos seems to have been to thwart the ambitious instincts of his brilliant Faulconbridge. For in the boiling veins of the young prince abided the whole soul of Charles V.,--valour, restlessness, ambition; and his romantic life and mysterious death bear alike the tincture of his parentage. That was indeed the age of the romance of royalty! Mary at Holyrood,--Elizabeth at Kenilworth--Carlos at the feet of his mother-in-law,--the Béarnais at the gates of Paris,--have engraved their type in the book of universal memory. But Don John escapes notice--a solitary star outshone by dazzling constellations. Commemorated by no medals, flattered by no historiographer, sung by no inspired "godson," anointed by neither pope nor primate, his nook in the temple of fame is out of sight, and forgotten.
