way the triptych is also a musical homage to the work of the group of French composers associated with Cocteau, Les Six (and especially to Glass's teacher Darius Milhaud), as well as to various 18th-century composers such as Gluck and Bach whose music featured as an essential part of the films by Cocteau. The inspiration of the first part of the trilogy, Orphée (composed in 1991, and premiered in 1993 at the American Repertory Theatre) can be conceptually and musically traced to Gluck's opera Orfeo ed Euridice (Orphée et Euridyce, 1762/1774), which had a prominent part in Cocteau's 1949 film Orphee. One theme of the opera, the death of Eurydice, has some similarity to the composer's personal life: the opera was composed after the unexpected death in 1991 of Glass's wife, artist Candy Jernigan: "... One can only suspect that Orpheus' grief must have resembled the composer's own", K. Robert Schwartz suggests. The opera's "transparency of texture, a subtlety of instrumental color, ... a newly expressive and unfettered vocal writing" was praised, and The Guardian's critic remarked "Glass has a real affinity for the French text and sets the words eloquently, underpinning them with delicately patterned instrumental textures". For the second opera, La Belle et la Bête (1994, scored for either the Philip Glass Ensemble or a more conventional chamber orchestra), Glass replaced the soundtrack (including Georges Auric's film music) of Cocteau's film, wrote "a new fully operatic score and synchronize[d] it with the film". The final part of the triptych returned again to a more traditional setting with the "Dance Opera" Les Enfants terribles (1996), scored for voices, three pianos and dancers, with choreography by Susan Marshall. The characters are depicted by both singers and dancers. The scoring of the opera evokes Bach's Concerto for Four Harpsichords, but in another way also "the snow, which falls relentlessly throughout the opera ... bearing witness to the unfolding events. Here time stands still. There is only music, and the movement of children through space" (Glass). 1997–2004: Symphonies, opera, and concertos In the late 1990s and early 2000s, Glass's lyrical and romantic styles peaked with a variety of projects: operas, theatre and film scores (Martin Scorsese's Kundun, 1997, Godfrey Reggio's Naqoyqatsi, 2002, and Stephen Daldry's The Hours, 2002), a series of five concerts, and three symphonies centered on orchestra-singer and orchestra-chorus interplay. Two symphonies, Symphony No. 5 "Choral" (1999) and Symphony No.
