And olibanum and myrrh from the queen of saba - I think itwas somewhere in ethiopia.
You mean Yemen - the trade routes went overland, north up the Arabian peninsula.
But Ethiopia was at the heart of a massive trade network that stretched from Zanzibar to India in ancient times, and up to the Mediterranean, all based around the Red Sea.
Another great trade route was the route over the Sahara Desert between Ghana (and, later, Mali) and the Muslim dynasties in modern Morocco and Tunisia. Thousands of camel-mounted caravans would make the month-long journey throughout the late Middle Ages: most of the gold in circulation in Renaissance Italy had been mined in Mali.
The Roman trade route east passed through Edessa, which was sometimes an independent city and sometimes under Roman rule. Edessa became great as the trade to and from the orient passed through it. More importantly, this was where ideas, beliefs, religions passed between the east and the Roman empire: Edessa therefore occupies a key place in religioius history.
London is also a very ancient trading centre, the gate of entry to Britain from the sea, which is one of the reasons it was founded by refugees from Troy (I'm reliably informed!). Another city which became prominent in this way was Oxford, built at a natural crossroads in the centre of England and surrounded by rivers on three sides.
