If you fancy listening to an art lecture by John Onians, who is Professor Emeritus of World Art at the University of East Anglia, now's your chance. He's on at 6.30pm tomorrow at the Louise T. Blouin Institute in London, admission £5. His subject: "Neuroarthistory: How the eye moves the artist's hand and how art moves us all". What Coxsoft Art wants to know is: 1) Does Prof. Onians know his onions? and 2) Do you get free coffee and biscuits?
