Reading the events of Muhammad Ali's great life is to be reminded or learn of the dynamic cultural environment in which he participated and to some extent he created.
Above is Muhammad Ali on a visit to Riyadh, Saudi Arabia, in 1972. Note how casually the princes around him are dressed, and posed, compared to the rigid and austere formalism that Saudi Arabia shows to the world today. If you think the America of Muhammad Ali's heyday looks like a different country than today, think of that comparison for Saudi Arabia.
