Art critic Martin Gayford looks back on the experience of sitting for a portrait by Lucian Freud over a number of months, with wry and revealing observations offering a kind of portrait of Freud himself.

He is the author of Man with a Blue Scarf, Rendez-vous with Art and A Bigger Message. He has collaborated with David Hockney on A Bigger Message: Conversations with David Hockney and A History of Pictures, and has co-written a volume of travels and conversations with Philippe de Montebello: Rendez-vous with Art.
