From Heroopolis, situated in that recess of the Arabian Gulf which is on the side of the Nile, to Babylon, towards Petra of the Nabataei, 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 Nabataei, Chaulotaei, and Agraei. Above these people is Arabia Felix, stretching out 12,000 stadia towards the south to the Atlantic Sea.Letronne here proposes to read Erythraean or Ethiopian Sea.
4.2
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,Mimosa Nilotica. and tamarisk; water is obtained by digging [wells] as in Gedrosia. It is inhabited by Arabian Scenitae, 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,This is remarkable. there are numerous herds of animals, mules (asses?), and swine; birds also of every kind, except geese and the gallinaceous tribe.
