Binyon, Painting in the Far East (1908), pp. 75-7, 146-7.  One of Chao Meng-fu’s horse pictures, or rather a copy of it by a Japanese artist, is reproduced in Giles, op. cit., opposite p. 159.  See also my notes on illustrations for an account of the famous landscape roll painted by him in the style of Wang Wei.
