Until recently, there was little practical knowledge of the ships of the distant past. We could only surmise as to the manner in which a Viking ship sailed or how fast a Greek trireme could be rowed. The building of accurate replicas over the past generation has changed all that, and what has been learnt about the ships and boats of our ancestors has radically changed our perceptions of sailing and voyaging. This beautifully-illustrated new book charts those discoveries. The world s leading authorities look at individual replicas and discuss what they have taught us.
