David Robie, concluding his three-part series about Iran, profiles an extraordinary pair of Tehran brothers who have been pioneering global research adventurers. They have been dubbed the “Persian Indiana Joneses”. Their adventures are fabled and hair-raising, as shown by a Jivaro shrunken human head and relics from curious rituals on display from almost 70 years ago. But the Omidvar brothers were no gung-ho adventurers, merely gate-crashing hidden tribal and indigenous communities around the world. They were also no elitists.
