Sardinia in Arabic sources

The purpose of this paper is to examine Arabic sources, which I have already used in three previous articles published in 2001 and 2002, with the aim to discover: a) if there is a connection with the results of the studies on Sardinia and b) to discover sources of Arab authors. One of the aspects which cuts across my analysis and the work of previous professors who have taught and some of whom still teach at the Universities of Cagliari and of Sassari, is the research on the waves of the peoples who have inhabited Sardinia; this subject is one of the themes which I shall try to examine through Arabic sources.
