The Norwegian explorer Thor Heyerdahl, never one to shrink from a challenge, visited Gobustan in Azerbaijan for two decades to prove his theory that the ancestors of today’s Scandinavians left behind the mysterious rock carvings near Baku. Uncanny similarities between petroglyphs showing the long, oared boats of Caspian seafarers and those of the Vikings, and between other rock carvings in both Azerbaijan and Norway tantalized Heyerdahl.

Mesopotamia is having a moment. Moudhy Al-Rashid’s Between Two Rivers: Ancient Mesopotamia and the Birth of History, joins among others Land Between the Rivers: A 5,000-Year History of Iraq by Bartle Bull, The Center of the World: A Global History of the Persian Gulf from the Stone Age to the Present by Allen James Fromherz and, some more esoterically, Enheduana: The Complete Poems of the World’s First Author by Sophus Helle, all released in the last 12 months or so.

English. French. Italian. Hindi. Greek. Russian. All these different languages can trace their roots to the same origin: Proto-Indo-European, spoken in 4000 BC in the steppe that crosses from Eastern Europe to Central Asia. Whether by migration, diffusion or conquest, the Indo-European languages spread west across Europe, east across Central Asia, and southeast towards India.

If you only read one book by the prolific and (now) venerable John Man, it should perhaps be this one, literally so for it “revises and condenses” several chapters in his other books Genghis Khan, The Terracotta Army, Barbarians at the Wall, The Great Wall and Xanadu. It is, as one might expect from Man, a very readable amalgam of history, storytelling and travel-writing.

Few subjects have progressed as rapidly in recent years as the study of prehistory and ancient history. The ability to decode the human genome has upended everything. In retrospect, archaeologists and linguists got an amazing amount right; the advent of DNA analysis (backed up by huge amounts of computing power) provided a layer of scientific confidence, allowing the other disciplines to progress faster and more accurately.

Geographic labels are sometimes misnomers. The Dead Sea’s name is not, for the most part. Its high salinity levels kill most forms of life, barring a couple hardy microbes and algae—and even these are threatened by environmental change. Except the Dead Sea has been part of human history for millennia. Jericho, the world’s oldest city, sits nearby. It features prominently in the Bible. Greeks, Romans, Jews, Arabs, Europeans all interact with the Dead Sea. And it’s now a tourist hotspot, a source for resources extraction–and a political hotspot, shared between Jordan, Israel, and the contested area of the West Bank.
