Andrea Teodoro Zani (11 November 1696 – 28 September 1757) was an Italian violinist and composer.

Zani was born at Casalmaggiore in the Province of Cremona. He received his first instruction in playing the violin from his father, an amateur violinist. Subsequently, he received instruction in composition from Giacomo Civeri, a local musician, and studied violin in Guastalla with the court violinist Carlo Ricci. Antonio Caldara, who was working as Capellmeister at the court of Archduke Ferdinand Charles in Mantua, not far from Casalmaggiore, heard Zani play and invited him to accompany him to Vienna. Between 1727 and 1729 Zani arrived in Vienna and was active there as a violinist in the service of the Habsburgs. Following the death of his sponsor Caldara in 1736, he returned to Casalmaggiore where he remained for the rest of his life, except for occasional concert appearances. He died in his home town as the result of an accident, when the carriage in which he was travelling to Mantua overturned.

Louis-Claude Daquin (or d'Acquin), (July 4, 1694 – June 15, 1772) was a French composer of Jewish birth writing in the Baroque and Galant styles. He was a virtuoso organist and harpsichordist.

Louis-Claude Daquin was born in Paris, to a family originating from Italy (where their name was D'Aquino). One of his great-uncles was a professor of Hebrew at the Collège de France. Daquin was a musical child prodigy. He performed for the court of King Louis XIV at the age of six. He was for a while a pupil of Louis Marchand. At the age of 12, he became organist at the Sainte-Chapelle, and in the following year took a similar post at the church of the Petit St. Antoine.

Claude Daquin never lacked for work as an organist. In 1727 he was appointed organist at the church of St. Paul in Paris, ahead of Jean-Philippe Rameau who was also a candidate. Five years later he succeeded his teacher Louis Marchand as organist at the Église des Cordeliers. In 1739 he became organist to the king. In 1755 he was made titular organist at the cathedral of Notre-Dame de Paris, succeeding Antoine Calvière.

William Blake (28 November 1757 – 12 August 1827) was an English poet, painter, and printmaker. Largely unrecognised during his lifetime, Blake is now considered a seminal figure in the history of both the poetry and visual arts of the Romantic Age. His prophetic poetry has been said to form "what is in proportion to its merits the least read body of poetry in the English language". His visual artistry has led one contemporary art critic to proclaim him "far and away the greatest artist Britain has ever produced". Although he lived in London his entire life except for three years spent in Felpham he produced a diverse and symbolically rich corpus, which embraced the imagination as "the body of God", or "Human existence itself".

Considered mad by contemporaries for his idiosyncratic views, Blake is held in high regard by later critics for his expressiveness and creativity, and for the philosophical and mystical undercurrents within his work. His paintings and poetry have been characterised as part of both the Romantic movement and "Pre-Romantic", for its large appearance in the 18th century. Reverent of the Bible but hostile to the Church of England – indeed, to all forms of organised religion – Blake was influenced by the ideals and ambitions of the French and American revolutions, as well as by such thinkers as Jakob Böhme and Emanuel Swedenborg. Despite these known influences, the singularity of Blake's work makes him difficult to classify. The 19th-century scholar William Rossetti characterised Blake as a "glorious luminary," and as "a man not forestalled by predecessors, nor to be classed with contemporaries, nor to be replaced by known or readily surmisable successors".

Giuseppe Domenico Scarlatti (26 October 1685 – 23 July 1757) was an Italian composer who spent much of his life in the service of the Portuguese and Spanish royal families. He is classified as a Baroque composer chronologically, although his music was influential in the development of the Classical style. Like his renowned father Alessandro Scarlatti he composed in a variety of musical forms, although today he is known mainly for his 555 keyboard sonatas.

Domenico Scarlatti was born in Naples, Kingdom of Naples, in 1685, the same year as Johann Sebastian Bach and George Frideric Handel. He was the sixth of ten children and a younger brother to Pietro Filippo Scarlatti, also a musician. He probably first studied under his father, the composer and teacher Alessandro Scarlatti; other composers who may have been his early teachers include Gaetano Greco, Francesco Gasparini, and Bernardo Pasquini, all of whom may have influenced his musical style.

He became a composer and organist at the royal chapel in Naples in 1701. In 1704, he revised Carlo Francesco Pollarolo's opera Irene for performance at Naples. Soon afterwards, his father sent him to Venice. After this, nothing is known of Scarlatti's life until 1709, when he went to Rome in the service of the exiled Polish queen Marie Casimire. He met Thomas Roseingrave there. Scarlatti was already an eminent harpsichordist: there is a story of a trial of skill with George Frideric Handel at the palace of Cardinal Ottoboni in Rome where he was judged possibly superior to Handel on that instrument, although inferior on the organ. Later in life, he was known to cross himself in veneration when speaking of Handel's skill. In Rome, Scarlatti composed several operas for Queen Casimira's private theatre. He was Maestro Di Cappella at St. Peter's from 1715 to 1719. In 1719 he travelled to London to direct his opera Narciso at the King's Theatre.
