Dr Cat Jarman exposes the unexpected routes that Viking travel and trade took - and how these kings of the river were frequent travellers of the Middle East and the Silk Road.One June day late in the eighth century, Norse seafarers arrived at the English island of Lindisfarne. They waged a savage attack on its unsuspecting abbey, and with this, the Age of the Vikings was born. These roving pillagers spent the next few hundred years raiding and trading a path across Northern and Western Europe. Except, that's not quite true. It's just a convenient place to start the story - a story that has seen radical new discoveries over the past few years. Dr Cat Jarman works on the cutting edge of bioarchaeology, using forensic techniques to research the paths of Vikings who came to rest in British soil. By examining teeth that are now over one thousand years old, she can determine childhood diet, and thereby where a specimen was likely born. With radiocarbon dating, she can ascertain a death date down to the range of a few years. In 2012, a carnelian bead came into her temporary possession. River Kings sees her trace its path back to eighth-century Baghdad, discovering along the way that the Vikings' route was far more varied than we might think, that with them came people from the Middle East, not just Scandinavia, and that the reason for all this unexpected integration between the Eastern and Western worlds may well have been a slave trade running through the Silk Road, and all the way to Britain. River Kings is a major reassessment of the Vikings, and of the medieval world as we know it.

    It was a sea in name only. It was actually a bone dry, ancient dusty basin pockmarked with craters and littered with rocks and boulders. Somewhere in that 500 mile diameter basin, the astronauts would attempt to make Mankind’s first landing on the Moon. Neil Armstrong would pilot the Lunar Module “Eagle” during its twelve minute descent from orbit down to a landing. Col. Edwin “Buzz” Aldrin would assist him. On the way down they would encounter a host of problems, any one of which could have potentially caused them to have to call off the landing, or, even worse, die making the attempt. The problems were all technical-communications problems, computer problems, guidance problems, sensor problems. Armstrong and Aldrin faced the very real risk of dying by the very same technical sword that they had to live by in order to accomplish the enormous task of landing on the Moon for the first time. Yet the human skills Armstrong and Aldrin employed would be more than equal to the task. Armstrong’s formidable skills as an aviator, honed from the time he was a young boy, would serve him well as he piloted Eagle down amidst a continuing series of systems problems that might have fatally distracted a lesser aviator. Armstrong’s brilliant piloting was complemented by Aldrin’s equally remarkable discipline and calmness as he stoically provided a running commentary on altitude and descent rate while handling systems problems that threatened the landing. Finally, after a harrowing twelve and a half minutes, Armstrong gently landed Eagle at “Tranquility Base”, a name he had personally chosen to denote the location of the first Moon landing. In “Landing Eagle-Inside the Cockpit During the First Moon Landing”, author Mike Engle gives a minute by minute account of the events that occurred throughout Eagle’s descent and landing on the Moon. Engle, a retired NASA engineer and Mission Control flight controller, uses NASA audio files of actual voice recordings made inside Eagle’s cockpit during landing to give the reader an “inside the cockpit” perspective on the first Moon landing. Engle’s transcripts of these recordings, along with background material on the history and technical details behind the enormous effort to accomplish the first Moon landing, give a new and fascinating insight into the events that occurred on that remarkable day fifty years ago.
