ADAMSON, Ian. Dalaradia: Kingdom of the Cruthin. Belfast: Pretani, 1998. 137pp. Hardback.[`As the people of Northern Ireland take their first tentative steps on the road to a new pluralist society and endeavour to come to terms with the divisions created during the last few hundred years of history, it is timely to remind them that they have another, more ancient legacy - a shared historical and cultural inheritance of which most of them are largely unaware. Among the oldest named population groups of Ireland were the Cruthin, a pre-Celtic people dominant in large parts of ancient Ulster. Their most powerful dynasty were the Dal nAraidi, whose territory became known as Dalaradia, and whose impact upon Ulster's history and culture is detailed in this book']. IRISH
