In the latter year he finished second in a competition to write music for William Congreve's masque The Judgement of Paris (the winner was John Weldon).
Recognizing Eccles’s ability to write for her needs, Mrs Bracegirdle, undoubtedly under his tutelage, thereafter sang only his music.
[1] Eccles also wrote an all-sung English opera Semele with text by Congreve, but it was not staged until the 20th century.
For much of the later part of his life, Eccles lived in Kingston upon Thames and wrote additional incidental music (though not as frequently as he had for Lincoln's Inn Fields) as well as the occasional court ode.
[2] Eccles’s major opera, Semele, can be found in volume 76 of Musica Britannica, edited by Richard Platt.
