According to Jean Paul Sartre, he was ‘the most complete man of his age’. John Berger likened the photograph of his corpse to Andrea Mantegna’s ‘Dead Christ’. When I went up to university, in the month of his death, October 1967, the walls were quilted with his image — the famous Korda photograph of the implacable revolutionary, with the beret, the Comandante star, the wispy hair and beard. I remember particularly a sickly poster version in psychedelic colours — mauve and turquoise and green — taped to the wall of a friend’s room.
