The monograph "Klenoder" presents 30 selected objects/finds from the Iron Age (ca 400 BC-1050 AD). The selected "crenodes" are placed in their cultural-historical context and with their help a story is told about a relatively unknown period in Swedish history. The presentation is not limited to the historical context of the objects, but the stories also include those who found them, those who researched and interpreted them and those who exhibited them in different contexts. In this way, the reader gains an understanding and knowledge of the historical period of the Iron Age, but also an insight into how history is constantly interpreted and reinterpreted. And also how museum objects can be reconstructed in new ways as a result of new knowledge. The "gems" selected range from a gold collar and a Vendel helmet to a modest Chinese silk fragment found in a Viking tomb at Birka. With the help of the objects/finds, the reader becomes acquainted with those who once used the objects but also with the time they belong to. The presentation is illustrated with a number of pictures of objects, investigators, finders, exhibition pictures, archaeological sites and people who in some way came into contact with the objects. The language is written to attract a public interested in cultural history.
