As a kid, I’d write letters to George Bass, an American professor of underwater archaeology who used to contribute to National Geographic magazine. He actually responded, and we carried on this correspondence for many years — me begging him to take me along on one of his expeditions, him always finding a reason not to. Until, many years later [following Mensun’s studies in ancient history and archaeology], he asked if I could be on the Greek island of Kos in a week’s time. I didn’t ask any questions. This was my open door, and I walked through it.
