Question: Who was the "king's engineer" to the  King of Portugal, Naples, Sicily and Sardinia and Duke of Milan?
Context: Philip II (Spanish: "Felipe II" ; 21 May 1527 – 13 September 1598), called "the Prudent" (el Prudente), was King of Spain (1556–98), King of Portugal (1581–98, as "Philip I", "Filipe I"), King of Naples and Sicily (both from 1554), and "jure uxoris" King of England and Ireland (during his marriage to Queen Mary I from 1554–58).  He was also Duke of Milan.  From 1555, he was lord of the Seventeen Provinces of the Netherlands. Stephen of Durazzo (born Stefano di Durazzo, later known as Estêvão de Nápoles in Portugal) (c.1320-1380) was an Italian nobleman and warrior, the claimed youngest son of John, Duke of Durazzo, ruler of the Kingdom of Albania, by his wife Agnés de Périgord and a grandson of king Charles II of Naples.  But this is a posterior fabrication, as the origin of the surname de Nápoles, for there is no notice of any such legitimate or bastard son of a Prince of Naples.  He moved to Portugal as a crusader, having fought the Moors alongside "his cousin" king Afonso IV of Portugal at the battle of Salado, as mentioned in Duarte Nunes de Leão's "Chronicles of the Kings of Portugal".  Known in Portugal as Estêvão de Nápoles ("Stephen of Naples"), he gave origin to the Portuguese family Nápoles, a false branch of the royal Capetian House of Anjou-Naples. Southern Italy or Mezzogiorno (] , literally "midday") is a macroregion of Italy traditionally encompassing the territories of the former Kingdom of the two Sicilies (all the southern section of the Italian Peninsula and Sicily), with the frequent addition of the island of Sardinia.  It generally coincides with the administrative regions of Abruzzo, Apulia, Basilicata, Campania, Calabria, Molise, Sicily, and usually Sardinia.  Some also include the southernmost and easternmost parts of Lazio (the Sora, Cassino, Gaeta, Cittaducale, Formia, and Amatrice districts) within the "Mezzogiorno", since they were once part of the Kingdom of the Two Sicilies.  The island of Sardinia, although for cultural and historical reasons having less in common with the aforementioned regions, is frequently included as Southern Italy or "Mezzogiorno", often for statistical and economical purposes. The Duke of Carcaci (Italian: "Duca di Cárcaci" ) (pron: "Car-catch-ee") is the head of one branch of the Paternò Castello family, an ancient Sicilian noble family.  The estate of Cárcaci, from which the dukedom is named, is situated in Sicily, 20 miles north-west of Catania (where survives the ducal palazzo), at the junction of the River Simeto and River Salso.  It is thus situated about 15 miles west of the crater of Mount Etna.  The historic estate of Paternò, now a town, is situated about 10 miles north-west of Catania, midway between that town and Carcaci.  The first Duke of Carcaci was Don Vincenzo Paternò Castello (1681–1767) who in 1725 was created a duke of the Kingdom of Naples by Charles VI, Holy Roman Emperor and King of Naples, who had gained control of the Kingdom of Naples in 1714 and of Sicily in 1720.  Carcaci had become the seat of a feudal barony shortly after the Norman Conquest of Sicily in 1061, when the first castle was built on the site.  The barony and estate was not acquired by this branch of the Paternò Castello family, the principal historic seat of the senior line of which was Paternò Castle, until 1719. James II (10 August 1267 – 2 or 5 November 1327), called the Just, was the King of Aragon and Valencia and Count of Barcelona from 1291 to 1327.  He was also the King of Sicily (as James I) from 1285 to 1295 and the King of Majorca from 1291 to 1298.  From 1297 he was nominally the King of Sardinia and Corsica, but he only acquired the island of Sardinia by onquest in 1324.  His full title for the last three decades of his reign was "James, by the grace of God, king of Aragon, Valencia, Sardinia and Corsica, and count of Barcelona" (Latin: "Iacobus Dei gracia rex Aragonum, Valencie, Sardinie, et Corsice ac comes Barchinone"). Maria Cristina of Naples and Sicily (Maria Cristina Amelia Teresa; 17 January 1779 – 11 March 1849) was a Princess of Naples and Sicily and later Queen of Sardinia as wife of King Charles Felix. Tiburzio Spannocchi (1541–1609) (also Spanucchi, Spanochi, Spanoqui, Hispanochi etc.) was "king's engineer" to Philip II of Spain and subsequently to Philip III of Spain.  He was named "Chief Engineer" in 1601. Philip III (Spanish: "Felipe" ; 14 April 1578 – 31 March 1621) was King of Spain.  He was also, as Philip II, King of Portugal, Naples, Sicily and Sardinia and Duke of Milan. Maria Theresa of Austria (21 March 1801 – 12 January 1855) was born an Archduchess of Austria and Princess of Tuscany.  She was a daughter of Ferdinand III, Grand Duke of Tuscany, and Luisa of Naples and Sicily.  She was named after her double great grandmother Empress Maria Theresa.  In 1817, she married Charles Albert of Sardinia and subsequently became the Queen of Sardinia upon her husband's accession to the throne in 1831. René of Anjou (Occitan: "Rainièr d'Anjau" ; French: "René d'Anjou" ; 1409–1480), also known as René I of Naples (Italian: "Renato I di Napoli" ) and Good King René (Occitan: "Rai Rainièr lo Bòn" ; French: "Le bon roi René" ), was count of Piedmont, Duke of Bar (1430–80), Duke of Lorraine (1431–53), Duke of Anjou, Count of Provence (1434–80), King of Naples (1435–42; titular 1442–80), titular King of Jerusalem (1438–80) and Aragon including Sicily, Majorca and Corsica (1466–70).
