As a start, I find in my collection odes by G B Draghi and John Blow, A
Scarlatti's Messa di Santa Cecilia, and an Ode and Alexander's Feast by
Handel.  Actually there are several Odes to Saint Cecilia by Purcell;
beginning in 1683 there was apparently an annual celebration on Saint
Cecilia's day in London for which Purcell wrote many of the feature
attractions, including "Hail, Bright Cecilia" in 1692.  Any others?

Best regards to all--
