The decoding of Linear B is one of the world''s greatest stories: from the discovery of a cache of ancient tablets recording a lost prehistoric language to the dramatic solution of the riddle nearly seventy years later, it exerts a mesmerising pull on the imagination. But this captivating story is missing a crucial piece. Two men have dominated Linear B in popular history: Arthur Evans, the intrepid Victorian archaeologist who unearthed Linear B at Knossos and Michael Ventris, the dashing young amateur who produced a solution. But there was a third figure: Alice Kober, without whose painstaking work, recorded on pieces of paper clipped from hymn-sheets and magazines and stored in cigarette boxes in her Brooklyn loft, Linear B might still remain a mystery. Drawing on Kober''s own papers - only made available recently - Margalit Fox provides the final piece of the enigma, and along the way reveals how you decipher a language when you know neither its grammar nor its alphabet as well as the stories behind other ancient languages, like the dancing-man Rongorongo of Easter Island.
