Another indication of the new direction his work was taking was the "Ode on the Music of the Grecian Theatre" that Collins proposed sending to Hayes in 1750. There, he asserted, "I have, I hope, Naturally introduc’d the Various Characters with which the Chorus was concern’d, As Oedopus, Medea, Electra, Orestes, &c &c. The Composition too is probably more correct, as I have chosen the ancient Tragedies as my Models." But all that has remained to substantiate this large claim is an 18-line fragment titled "Recitative Accompanied" and beginning "When Glorious Ptolomy by Merit rais'd".
