Nearchus says that he proved the confident belief of the sailors in the existence of an island situated in the passage, and destructive to those who anchored near it, to be false.
A bark in its course, when it came opposite to this island, was never afterwards seen, and some men who were sent in search did not venture to disembark upon the island, but shouted and called to the crew, when, receiving no answer, they returned. But as all imputed this disappearance to the island, Nearchus said that he himself sailed to it, went ashore, disembarked with a part of his crew, and went round it. But not discovering any trace of those of whom he was in search, he abandoned the attempt, and informed his men that no fault was to be imputed to the island (for otherwise destruction would have come upon himself and those who disembarked with him), but that some other cause (and innumerable others were possible) might have occasioned the loss of the vessel.
14. Carmania is the last portion of the sea-coast which begins from the Indus. Its first promontory projects towards the south into the Great Sea.[439] After it has formed the mouth of the Persian Gulf towards the promontory, which is in sight, of Arabia Felix, it bends towards the Persian Gulf, and is continued till it touches Persia.
Carmania is large, situated in the interior, and extending itself between Gedrosia and Persia, but stretches more to the north than Gedrosia. This is indicated by its fertility, for it not only produces everything, but the trees are of a large size, excepting however the olive; it is also watered by rivers. Gedrosia also differs little from the country of the Ichthyophagi, so that frequently there is no produce from the ground. They therefore keep the annual produce in store for several years.
Onesicritus says, that a river in Carmania brings down gold-dust; that there are mines of silver, copper, and minium; and that there are two mountains, one of which contains arsenic, the other salt.
There belongs to it a desert tract, which is contiguous to Parthia and Parætacene. The produce of the ground is like that of Persia; and among other productions the vine. The Carmanian vine, as we call it, often bears bunches of grapes of two cubits in size; the seeds are very numerous and very large; probably the plant grows in its native soil with great luxuriance.
Asses, on account of the scarcity of horses, are generally made use of even in war. They sacrifice an ass to Mars, who is the only deity worshipped by them, for they are a warlike people. No one marries before he has cut off the head of an enemy and presented it to the king, who deposits the scull in the royal treasury. The tongue is minced and mixed with flour, which the king, after tasting it, gives to the person who brought it, to be eaten by himself and his family. That king is the most highly respected, to whom the greatest number of heads are presented.
According to Nearchus, most of the customs and the language of the inhabitants of Carmania resemble those of the Persians and Medes.
The passage across the mouth of the Persian Gulf does not occupy more than one day.
