Nie inaczej sprawa miała się na hiszpańskim dworze naznaczonych dziedzicznym prognatyzmem Habsburgów i niezrównoważonych psychicznie Burbonów. Filipa V, cierpiącego na chorobę dwubiegunową, już tylko głos czekającego stale w pełnym napięcia pogotowiu Farinellego był w stanie otrząsnąć z maniakalno-depresyjnych ciągów.

Po śmierci władcy Farinelli wyjeżdża do Włoch, wywożąc ze sobą rękopisy 550 Sonat, które Scarlatti sporządził był wcześniej na zlecenie królowej Marii Barbary de Bragança.

(6) "The heart of ''Philip V of Spain'' is the story of one of the most idiosyncratic of European monarchs, who Kamen argues has been vastly misunderstood. Not directly in line for the French throne, as a youth Philip V was instilled with a sense of inadequacy. Moreover he suffered from fits of manic-depression possibly inherited from his Bavarian mother. Not worrisome when he first arrived in Spain, his disorder worsened as he aged until it devastated the court and the order of government. He suffered long periods of inaction and incongruous behavior from which some unpredictable development would rouse him to sudden hyperactivity. He would retire to his bedroom for days, refusing to bathe or dress, seeing no visitors or occasionally receiving them in his nightshirt. His black moods led him to abdicate in 1724 in favor of his son Louis, but when Louis died within the year, his spirits recovered and he reclaimed the throne (hence the book's subtitle, ''The King Who Reigned Twice''). In 1728 he initiated the extraordinary practice of staying up all night, sleeping by day. To their discomfort and dismay, he met his ministers and foreign ambassadors after midnight for sessions that lasted hours, and this went on until his death in 1746. Kamen rejects the view of Philip's contemporaries that he was mad, and basing his opinion on a review of current medical literature, he attributes the king's eccentric behavior to a bipolar mentality.
Two forces in particular could turn Philip from a melancholy recluse into a happy, active monarch. One was taking a personal role in diplomacy and in military campaigns. In these he directed his energies to the recovery of the position Spain lost in Italy in 1713. His tenacity achieved considerable success, for he established his son Charles as King of Naples and Sicily. The other force was the companionship and support of his wives. First was Marie Louise, daughter of the Duke of Savoy, to whom he was married in 1701. He was 18 years old, she 13 but strong-willed and capable of leading the government in his absence. Kamen shows the pair falling madly in love and Philip finding new life when he returned to her arms from his campaigns. Marie Louise died in 1714, leaving Philip devastated, but before the year was out he had a new queen, from Italy, Elizabeth Farnese of Parma. Again Philip found love and solace in his wife. Elizabeth had the strength to handle his moods and devoted herself to caring for him, assuaging his depressions and protecting his public image. Late in his life she discovered another source of comfort for the troubled king -- the famous castrato voice of Farinelli. Brought to live at the Spanish court, Farinelli was on call at any hour of the night to dispel the king's melancholia."
