Dhofar in southern Oman has had a long association with the frankincense trade. The most active period was from the first century BC to the fourth century AD. During this period the Roman Empire had a great demand for the precious gum. Classical authors say that there was a gold drain on their economy in the eastern empire such was the demand for it. Strabo says that sometimes there were caravans of 2000 camels at one time although it is not known whether such large caravans travelled from Dhofar or from present-day Yemen (1).
Wendell Phillips wrote about frankincense in the 1950s and 60s: “The ancient kings of Hadramaut had to secure Andhur Oasis to control the vital frankincense trade; the fortress on the ridge was designed to accomplish this objective. Even today (1960) camel trails can be seen leading out to the north-west in the direction of Shisr; another route leads west-south-west to the post of Hanun, where the frankincense collection centre described above was partially cleared… Mirbat is only 40 miles due south of Andhur Oasis, but a direct route is rendered impossible by the precipitous southern face of the intervening Jabal Samhan…” (2). Some Mahra interviewed by him stated that it took 3 or 4 days’ camel journey to reach Salalah from Andhur.
I dispute Philips saying that there was no direct route down Jebel Samhan to Mirbat. In 1999 three Dhofari friends and I walked along the top of the escarpment east of Mirbat until we reached Wadi Kharis (about 1700 m.). This deep valley runs north south and eventually leads to Wadi Andhur 40 km to the north. However, we descended the cliff face along an old narrow camel track and came out at Sawb on the plains near Jufa. This is one of the few places where it’s possible to come down the cliff between Mirbat and Hadbeen.
Frankincense was exported from ports along the Dhofar coast up until the 1950s. Of course frankincense is still exported today although in much smaller quantities. Frankincense harvested from the eastern Dhofar mountains — that is the mountains above Mirbat, also known as Solot — was transported by camel to Mirbat and further to the north-east, Hasik. In December 1894 Theodore Bent and his travelling party journeyed from Mirbat to Al-Haffa by baggala – an Arab sailing ship – which was carrying a ‘large cargo’ of frankincense for Bombay. The 40 mile journey from Mirbat to Al-Haffa took them two days because of opposing winds. However Bent comments that one of the songs the sailors sang was about frankincense (3).
