We have already seen at what an early period the trade with the land of frankincense, _i.e._ with South Arabia, grew up for Egypt, owing to the mutual intercourse of the Arabian tribes (I. 226). The first attempt of Egypt to open a communication by sea with South Arabia falls about the year 2300 B.C. At a period not later, other Arabian tribes must have carried the incense and spices of South Arabia to Elam, Ur and Nipur, and Babylon. Syria must have received the products of South Arabia first through Babylon, then by means of direct communication with the Arabs, and lastly by the special caravans of the Phenicians. We hear of two trade-roads to that land. One led past Damascus to the oasis of Duma (Dumat el Dshandal), and from thence through the interior of Arabia to the south; the other ran through Israel past Ashtaroth Karnaim, through the territories of the Ammonites, Moabites, and Edomites, to Elath, and thence led along the coast of the Arabian Gulf to the Sabæans (I. 320). From the Sabæans and the Chatramites even before the year 1500 B.C. the caravans brought not spices only and incense, but also the products of the Somali coast. The Sabæans traversed the Arabian Gulf and carried home the products of the coast of East Africa; the southwest coast of Arabia was no longer a place for producing and exporting frankincense and spices; it became the trading-place of the Somali coast, and before the year 1000 B.C. was also the trading-place for the products of India, which ships of the Indians carried to the shore of the Sabæans and Chatramites (I. 322). It must have been a considerable increase in the extent of the Phenician trade and the gains obtained from it, when the Phenicians were able to make such a fruitful use of their connection with South Arabia that it fell into their hands to provide Egypt, with her products, and perhaps even Babylonia also. Their caravan trade with South Arabia must have been lively, and the impulse to extend it strong, as they induced king Solomon to allow them to attempt a connection by sea from Elath with South Arabia. By the foundation and success of the trade to Ophir, and the most remote places of the East which they reached, their commerce obtained its widest extent, and brought in the richest returns. With incense and balsam, there came to Tyre cinnamon and cassia, sandal-wood and ivory, gold and pearls from India, and the silk tissues of the distant East.[539]
