At this time Don Pedro Giron, duke of Osuna and grandee of Spain, was viceroy of Sicily. He was a man of singular character; and the career he ran, in which Quevedo was involved, was as strange and various as was his disposition and designs.[115] The character of the Spanish, under the gloomy influence of Philip II., had become dignified, grave and ceremonious. His son Philip III. was of a different character. His father had taken pains to inculcate all his own bigotry in matters of religion, and, at the same time, to inspire him with application, judgment, and a knowledge of the arts of government. In the first part of his education he succeeded; in the latter he wholly failed. Philip III. was a weak prince and as such given up to favouritism. On coming to the crown, he devolved all the labours of government on the marquis of Denia whom he made duke of Lerma, who again entrusted much of the royal patronage and power to Don Rodrigo de Calderon, a man of low birth, but of high and haughty mind, who became count of Oliva and marquis de Siete Iglesias. The court of Philip III., however, preserved much of the dignity, the severe etiquette and solemn gravity brought in by Philip II. In this serious and ceremonious circle the duke of Osuna was almost regarded as a madman. He displayed the fervour and spirit of youth in a gaiety and recklessness of manner and behaviour, wholly at war with courtly decorum and seriousness. His wit was brilliant, his understanding penetrating, his imagination full of fire and extravagance; his temper ardent and joyous. He was often called insane, and the sober tried to bring him into disesteem. His high birth and vast fortunes, however, gave him rank and weight, and he had distinguished himself in the wars of the Low Countries, not only by his bravery but by his military skill. His disposition prompted him to love the trade of war; and he made such use of his experience during the struggle carried on in that disturbed country, that he became reputed fit to command an army. His valour was undoubted; on one occasion he had three horses killed under him, and the success that attended his enterprises surrounded them with still greater lustre. He was licentious in his habits, but so grossly so, that he was never the slave of love. His ambition was unbounded; his designs vast: his imagination suggested a thousand strange modes of satisfying it, and engendered schemes so wild and daring that, while the world was amazed, and its repose disturbed, their very singularity, in many instances, commanded success. His military reputation was the cause, joined to the influence of Uzeda, son of the duke of Lerma, who was his friend, that, notwithstanding his indiscretions and levity, he came to be named viceroy of Sicily.
