Indian trade between the Gulf and the Red Sea

This essay evaluates the relative importance of the maritime trade between the Roman Empire and India along two routes that were in use: one started and ended on the Egyptian shore of the Red Sea, the other at the head of the Gulf. Both continued on land along caravan tracks to the Nile valley or through the Syrian desert to Palmyra. The latter land route, longer and presumably more cost-consuming, was used only during the 1st to 3rd centuries AD. The land link with the Far East, the so-called Silk Road, does not seem to have been regularly used. A document from Palmyra allows to estimate the value of the trade along the Syrian route as much smaller than that of the Red Sea traffic. It could have been mainly of local, Syrian importance, and lasted only as long as political circumstances allowed.
