From these first successes, the Festival has made a significant impact on the operatic culture of Britain with new productions of rarely performed operas (such as Britten's "Let's Make an Opera" (1980); Domenico Cimarosa's "Il matrimonio segreto" (1981 and 1993); Kodály's "Háry János" (in its British stage premiere in 1982); Vivaldi's "Griselda" (1983, but not seen anywhere since its original Venice presentation in 1735); Cherubini's Médée (1984, in its original French dialogue never seen in Britain); and, from 1986, many productions of Handel's operas, as well as many others by Cimarosa (in 1989 it presented three).
