Nicola Matteis (Matheis) (c. 1650 – after 1713[1]) was the earliest notable Italian Baroque violinist in London, whom Roger North judged in retrospect "to have been a second to Corelli," and a composer of significant popularity in his time, though he had been utterly forgotten until the later 20th century.
He came to London in the early 1670s and according to the diarist Roger North, had a city merchant as a sponsor, who schooled him in the ways of currying favor from the gentry (by allowing them to accompany him in parlor recitals and other minor performances).
His reputation grew through his lifetime and resulted in high praise for his live performances (in concert, audiences were often certain that more than one violin was being played) and widespread popularity for his music.
Knowing many of his customers were amateurs, Matteis tended to give precise instructions in the prefaces to his published Ayres, providing detailed notes on bowing, explanations of ornaments, tempos, and other directions.
His son, Nicola (died 1749), was likewise a good violinist, and lived for a long time in Vienna, but later resided in Shrewsbury as a violin and language teacher, and had Charles Burney among his students.
