"Prospero wears a large, heavy, dark-blue cloak or gown that enfolds him like a quilted blanket... it is darkly embroidered with small wine-coloured beads and swirls of black vegetation... it has long strings and ornate tassels that trail to the ground... it is a garment that has often been worn... a little frayed and scuffed. Later it will be seen to be capable of changing colour... in seven stages comparable to the power of Prospero's magic... black, brown, dark blue, light blue, purple, dark red and fiery red... and to have a vivid lining embroidered with dazzling stars -- a lining that is only revealed in flashes as when a dark butterfly momentarily uncovers coloured underwings."
