My friend and I were talking about these today, and how even though popular belief holds that ancient societies were very inverted, when it is actually quite the opposite. I know of the Silk Route, the Amber Route, the Tin Route that the Carthaginians used, and the trans-Saharan caravans transporting gold, ivory and slaves. My friend also claimed there was a Cinnimon Route, across the Indian Ocean from Indonesia to Madagascar. Is there any evidence to support this claim? And have I missed any other main trade routes?
