THE appreciation of the life and work of Professor Michael Sullivan, pictured, (October 10) is most welcome, not least because the Research Excellence Framework, due to publish its judgements next year, would almost certainly fail to value the breadth and depth of a contemporary Sullivan who, according to his close friend from their Cambridge student days, the architect, conservationist and artist, Thomas Affleck Greeves (1917-1997), knew everything and everybody.

For Sullivan was surely what great scholars must be: determinedly independent while always open to collaboration and the sharing of knowledge.

Everyone here in Oxford, and from beyond Oxford, should visit the Khoan and Michael Sullivan Gallery at the Ashmolean, much more than a jewel in the museum’s crown, while Professor Sullivan’s Chinese Art in the Twentieth Century should be essential reading.
