About 117 AD The Roman Ninth Legion, stationed in Britain where the city of York is now, went north to pacify one of the rebellious Caledonian tribes - and disappeared without a trace. Almost eighteen centuries later, during the excavations of ancient Kaleva, the cobbled streets of which are now covered with green fields, was unexpectedly discovered a wingless eagle, the standard of the lost legion, a cast of which can still be seen in the Reading Museum. Where did he come from? And what happened to the Ninth Legion after it was swallowed up by the northern mists? These two unsolved mysteries, tied together, served as the plot of the story “The Eagle of the Ninth Legion” - the first book of the trilogy by the English writer Rosemary Sutcliffe.
