Their Heads are Green, Their Hands are Blue deals largely with places in the world that few Westerners have ever heard of, much less seen—places as yet unencumbered by the trappings, luxuries, and corruptions of modern civilization. Bowles is a sympathetic and discerning observer of these alien cultures, and his eyes and ears are especially alert both to what is bizarre and what is wise in the civilizations in which he settles. Above all, Bowles is a superb and observant traveler—a born wanderer who finds pleasure in the inaccessible and who cheerfully endures the concomitant hardships with resourcefulness, insight, and humor.
