The geographical work of A l - I d r i s i, 'Nuzhat al-mushtaq fi khtiraq al-afaq', written for King Roger II, is well known, but its second treaty, the 'Uns al-muhadj wa-rawd al-furadj', it only came under scrutiny twenty years ago. A l - I d r i s i made the plan of the 'Uns' like that of the 'Nuzhat'. The world is divided into climates, with each climate being divided again into ten sections. The study of some parts of the 'Uns' shows that it is not a simple summary of the 'Nuzhat', but a rewriting with some additions, especially for Africa and the Meditteranean Europe. Poland and the Central Europe is situated in the third section of the sixth climate. But in this case, the text and the map are composed of a geographical material extracted from the 'Nuzhat', without real new information.
