Chapter on the
knowledge of the best of Inhabited lands
(the sun throws a shadow) on the inhabitants of the earth except those who are on the equator, a region of Middle-earth, they are the first residents to fill southern China and southern India and the country of Zinj and Al-Dybajat…
Hermes says that in that part (the southern part of the globe) there are climates that resemble these once (from the North), but that what makes it impossible for the people to get there is the big stretched ocean and the agitated violent sea, the power of the wind, the size of the waves and the far distance to make. Except that the ships also are at high risqué in the gulfs and sea arms, like the sea of Zinj and the Oriental Sea. But these are far from being the most important once, as the biggest obstacles consist, even in favourable times, of the distance and its wideness.
According to Hermes, the wise, the seven climates are: India, the Hijaz and Yemen, the land of Egypt, the land of Babylon, Land of the Romans, Gog and Magog, the land of China. They are grouped around the forth climate, the one of Babylon and in such a way that the first climate touches the seventh.
…The sea unites Oman to Jeddah the places of Yemen to the land of Zinj and Abyssinia…
…in north India and Sindh where we will meet the green sea – To go to the Sea Al-Zenj - and the Sea of Basra, and get to the Arabian Peninsula, Mecca and the Hijaz, the sea of Qulzoum and Upper Egypt…
He then describes different systems to divide the 7 climes as seen on this map of the seven climes from this manuscript.
Chapter on Differences in Opinions on Longitude and Latitude.
As to latitude; there are those who count the first clime from the equator till its northern boundary. Others make of the sea of the Zindj something separate between the first climate and the equator, this is then at 8deg 25min. There are there no days longer than 12.5 hours.

Chapter on what is reported by Claudius Ptolemaeus about the Nature of the Inhabitants of the inhabited land, in details.
Section between Maghreb and the South: The fourth quarter to the south of Maghreb, the country of Sudan Zinj the Abyssinians, the Beja, the Nuba, the Fezzan, the land of al-Qayrawan; and from Ifriqiyya, al-Qayrawan, the Sus, the lands of the naked blacks and Ghana which are called by other names such as Numidia and Gaetuli in the Greek tongue, it faces the triangle of Cancer. It is ruled by Venus and Mars…
As for the Nuba and all the Abyssinians, the Zinj and those adjacent to them from southern India, they resemble in nature both Scorpio and Mars. For that reason their moral conduct has become more like that of savage beasts than that of men. They have become people who squabble, who harbour enmities and disputes and things which are hateful and abhorrent. They deem life to be of little worth and they are not compassionate among one another. They do not show care and affection for each other and sometimes they are cruel to themselves; they destroy each other by burning, by throttling and by destruction in the pit……….
