Sir Constantijn Huygens, Lord of Zuilichem ( , , ; 4 September 159628 March 1687), was a Dutch Golden Age poet and composer. He was also secretary to two Princes of Orange: Frederick Henry and William II, and the father of the scientist Christiaan Huygens. Biography Constantijn Huygens was born in The Hague, the second son of Christiaan Huygens (senior), secretary of the Council of State, and Susanna Hoefnagel, niece of the Antwerp painter Joris Hoefnagel. Education Constantijn was a gifted child in his youth. His brother Maurits and he were educated partly by their father and partly by carefully instructed governors. When he was five years old, Constantijn and his brother received their first musical education. Music education They started with singing lessons, and they learned their notes using gold-coloured buttons on their jackets. It is striking that Christiaan senior imparted the "modern" system of 7 note names to the boys, instead of the traditional, but much more complicated hexachord system. Two years later the first lessons on the viol started, followed by the lute and the harpsichord. Constantijn showed a particular acumen for the lute. At the age of eleven he was already asked to play for ensembles, and later—during his diplomatic travels—his lute playing was in demand; he was asked to play at the Danish Court and for James I of England, although they were not known for their musical abilities. In later years he also learnt the more modern guitar. In 1647 he published in Paris his Pathodia sacra et profana with his compositions of airs de cour in French, madrigals in Italian and Psalms in Latin. Art instruction They were also schooled in art through their parents' art collection, but also their connection to the magnificent collection of paintings in the Antwerp house of diamond and jewellery dealer, Gaspar Duarte (1584–1653), who was a Portuguese Jewish exile. Language lessons Constantijn also had a talent for languages. He learned French, Latin and Greek, and at a later age Italian, German and English. He learned by practice, the modern way of learning techniques. Constantijn received education in maths, law and logic and he learned how to handle a pike and a musket. In 1614 Constantijn wrote his first Dutch poem, inspired by the French poet Guillaume de Salluste Du Bartas, in which he praises rural life. In his early 20s, he fell in love with Dorothea; however,
