To cover over 2 millennium of maritime trade, in the Middle East, India, SE Asia and China under 50 slides, can only give us the briefest gleam into the course of history. To get the benefit of the slides, you will need to set aside some time to read through the contents (This is a very wordy document. It takes time to read). Our perceptions on the maritime contacts are changing too. The discovery in particular of dozens of ancient shipwrecks in Southeast Asia has built up a picture of the historic trade and the technology.I hope in these few slides, would help to understanding an aspect of human civilization on Earth.
Too often our own ego-centric interest becomes a source of our own ignorance.
