Giles Hussey (1710–1788) was a painter from Dorset, England. His portraits are well regarded, but his theories on art never received the attention he craved. He believed that each note of music represented a colour. He created the first portrait of Charles Edward Stuart, the pretender to the British throne. Hussey has works in the Tate Gallery.
Hussey was born in 1710 at Marnhull in Dorset, the tenth of thirteen children of John and Mary Hussey. His parents sent him to receive a Catholic education in Douay and St Omer in France. On his return he was apprenticed to Jonathan Richardson to learn the art of portraiture. He then went on to work with Francesco Riari and he assisted in painting bishops in Lincoln Cathedral under the Venetian artist Vincenzo Damini. Damini is credited with saving Hussey from a potentially fatal fall while completing the paintings within porches at the cathedral, and got his reward when the two of them set out for Italy with monies from Hussey's parents.
After journeying through France in 1730, where substantial funds were spent, Damini abandoned Hussey in Bologna after taking his property. Hussey was lucky to be adopted by a former ambassador to London, Signor Ghislonzoni, who befriended the painter, who was in Bolgna until 1733, when he left for his original destination of Rome.
In Rome he started to develop his own theories on art whilst working with Ercole Lelli. His intention was to use his knowledge of mathematics to identify what made artistic beauty. He measured many ancient statues and claimed to have found a "Harmonic Scale" that was important to their beauty and construction. Hussey proposed that the musical notes could be aligned with the colours of the spectrum. Red was meant to indicate "A" whilst violet was meant to indicate A flat.
The illustration shows one of the portraits that Hussey made of the "Young Pretender", Charles Edward Stuart, who was the embodiment of the Catholic cause in England. These portraits were accurate, but were considered to have suffered from Hussey's obsession with his theories. Hussey is credited with being the first British artist to create a portrait of Charles Edward Stuart. The first sitting is thought to have been in 1734 and a number of different versions were produced. The second sitting has been dated to 1737 and shows Charles as a knight in a black suit of armour owned by him. An oil painting of this sketch was reported, but its current location is not known.
