An interlude describing her journey alludes musically to the Scene 4 aria before transitioning to the construction site the following morning, where a ceremony is taking place to mark the completion of the roof’s vast concrete vaults. Much to the embarrassment of the new government officials, the workers ironically unfurl their Union’s flag from the pinnacle. The spirit of “Sky” in the guise of a tour guide explains how the arches will be covered in a million white tiles, “glazed and unglazed, like snow and ice”.
[29’02”] The Architect appears and in an ill-judged stunt, throws himself at the Politician’s feet, literally begging for extra funding. His new political master is furious and the departing crowd revoice their original doubts about the foreigner’s sanity. The Engineer is also seething and it becomes clear that this farcical act has come at the peak of a serious rift between the former friends.
[32’25”] In an arioso, he expresses the dilemma of a practical mind having to make concrete another’s utopian fantasies, and tries to argue that his methodology is beautiful in its own way. The Architect’s feelings are hurt and the two depart on uneasy terms.
[35’00”] From the scaffolding in the distance, the strains of the “Britannia” aria are heard. The Architect recognises the voice as Alexandra’s and, as the clearly distraught woman is escorted from the hazard zone by wolf-whistling workers, kindly takes her aside. All too aware of the absurdity of her operatic “mad scene”, she expresses how she was “possessed” by the Architect’s vision but now despairs that her dream has been killed. Having encountered her husband on the Opera House Committee, the Architect guesses the source of tension.
[40’08”] He imparts to her his idealistic belief that all such obstacles shall melt away in the face of those “gifts” that need to be shared with humanity, and she finds comfort and rekindled optimism.
