The [Turkmen] are a numerous people of Turkish descent who conquered the land of Rūm in the period of the Seljuqs. They have become accustomed to raid the akritai who live on the coast, to take their possessions and sell them to the Muslims. Only the existence of a peace treaty (hudna) and the force of the sultan holds them back. They make Turkmen carpets which are exported. On their coast is a gulf called Macre which is famous among travellers, from which timber is exported to Alexandria and elsewhere. There is located the river of Baṭṭāl, which is deep. Across it is a bridge, which is lowered when there is peace (hudna) and raised when war breaks out, which is the border between the Muslims and Christians. The Baṭṭāl after whom it is named often raided Christians in Umayyad times and is mentioned in books of entertainment; his grave is there. To the north of the aforementioned Antalya are the mountains of Denizli, in which region and its surroundings are said to be around 200,000 Turkmen households, who are the ones called the ūj. The distance between it and the castle of Khūnās [Chonai/Honaz] where bows [?] are made is two farsakhs. The mountains of the Turkmen adjoin the lands of al-Lashkarī [the Lascarid], the ruler of Constantinople, from the gate of Denizli, and between Denizli and the bridge to its west is thirty miles. To its east is the Heraclea river which comes down from mount ʿAlāyā to Sinop, where there is Heraclea by the sea, which [Hārūn] al-Rashīd ruined. In its east is the mountain of the Cave in Rūm, where it is said the Cave [of the Seven Sleepers] is, which is mentioned in the history of al-Wāfiq, when someone was sent to gather intelligence on the ruler of Constantinople. Further east are the famous meadows where al-Muʿtaṣim was eager to pasture his horses from Iraq.
