What makes an object a treasure? To most people it is its cash value. To archaeologists this is usually negligible or even nil. To them it is solely what it can tell them, its value lies in its information. With this in mind, we have picked out 50 objects in Malta's National Collection, to describe that information value. It is from these, and of course from the sites where they were found, that the fascinating story of Malta's prehistoric past has been recovered.
