Ancient objects and other remains need to be interpreted to be understood. Often they contain several layers of knowledge that together increase our understanding of the past. "Big and Small Secrets" presents objects and remains from the Iron Age that hide "secrets", things that are not obvious at first glance. For example, the book tells how the Romans inspired the Norse to develop their own written language and how this was used in different ways by men and women. Later, during the Viking Age, the runes can also be used to shed light on literacy during the period in a slightly unexpected way. The book also shows how identity was created in different ways during the Iron Age. Through jewelry of various kinds but also by grinding your teeth. Individual objects can also be used to understand the development and change of political power and to trace political alliances and the like. Through thorough studies of, for example, burnt bones from graves, it is also possible to get close to individual people. Who they were, how old they were when they died, in some cases how they died and what their lives were like before they died. All in all, this makes the picture of the Iron Age a little clearer and brings us closer to the people of that time. The book will be richly illustrated with color pictures of objects, ancient remains, etc.
