He painted large biblical scenes in a style influenced by Burne-Jones and Renaissance art, and exhibited at the Royal Academy. When Ruskin employed him, Rooke worked in a different style, drawing in watercolours and painting from life. Later, Rooke painted records of architecture for the Society for the Preservation of Pictorial Records of Ancient Works of Art.
Ruskin on MosaicIn the course of his correspondence with Rooke, Ruskin wrote that 'The real
fact is that all Byzantine mosaic (and all Eastern colour) has splendour for its first object -- and its type is the peacock's tail.'
He adds, for Rooke's benefit, that 'If your drawings glow and melt like that you are right': 'Peacock's tail in shade or light it may be -- and much sober brown in
any light may mix with its violet and gold -- but
that is what the mosaicist wanted to do, and for the most part did'.
Ruskin concludes, provocatively, that 'All that is grey, cold, reserved, or modest, in these mosaics (in any other sense than a humming-bird or flamingo or pheasant -- or aforesaid peacock -- is modest) is European, mostly Roman, some of it German -- all of it bad.' (
