A Opening ceremonies artistic director Boyle came up with the theme "Isles of Won- der" after gaining inspiration from Caliban's speech in The Tempest which opens with the line: "Be not afeard; the isle is full of nois-es." He told the BBC that the speech will be inscribed(铭刻) on a 27-tonne bell which will be rung in the Olympic Stadium to reflect the start of the Games.
