2. I return to the opinions of Eratosthenes, which he next delivers respecting Arabia. He is speaking of the northern and desert part, lying between Arabia Felix, Cœle-Syria, and Judæa, to the recess of the Arabian Gulf. From Heroopolis, situated in that recess of the Arabian Gulf which is on the side of the Nile, to Babylon, towards Petra of the Nabatæi, are 5600 stadia. The whole tract lies in the direction of the summer solstice (i. e. east and west), and passes through the adjacent Arabian tribes, namely Nabatæi, Chaulotæi, and Agræi. Above these people is Arabia Felix, stretching out 12,000 stadia towards the south to the Atlantic Sea.[693] [CAS. 768] The first people, next after the Syrians and Jews, who occupy this country are husbandmen. These people are succeeded by a barren and sandy tract, producing a few palms, the acanthus,[694] and tamarisk; water is obtained by digging [wells] as in Gedrosia. It is inhabited by Arabian Scenitæ, who breed camels. The extreme parts towards the south, and opposite to Ethiopia, are watered by summer showers, and are sowed twice, like the land in India. Its rivers are exhausted in watering plains, and by running into lakes. The general fertility of the country is very great; among other products, there is in particular an abundant supply of honey; except horses,[695] there are numerous herds of animals, mules (asses?), and swine; birds also of every kind, except geese and the gallinaceous tribe. Four of the most populous nations inhabit the extremity of the above-mentioned country; namely, the Minæi the part towards the Red Sea, whose largest city is Carna or Carnana.[696] Next to these are the Sabæans, whose chief city is Mariaba.[697] The third nation are the Cattabaneis,[698] extending to the straits and the passage across the Arabian Gulf. Their royal seat is called Tamna. The Chatramotitæ[699] are the furthest of these nations towards the east. Their city is Sabata. 3. All these cities are governed by one monarch, and are flourishing. They are adorned with beautiful temples and palaces. Their houses, in the mode of binding the timbers together, are like those in Egypt. The four countries comprise a greater territory than the Delta of Egypt.[700] The son does not succeed the father in the throne, but the son who is born in a family of the nobles first after the accession of the king. As soon as any one is invested with the government, the pregnant wives of the nobles are registered, and guardians are appointed to watch which of them is first delivered of a son. The custom is to adopt and educate the child in a princely manner as the future successor to the throne.
