I've been re-reading Lionel Casson's Travel in the Ancient World. I had forgotten just how interesting it is. I'd like to suggest that both it and his book on The Ancient Mariners: Seafarers and Sea Fighters of the Mediterranean in Ancient Times would be great additions to Logos. Both have helped illuminate the ancient world for me.

I often think that the ancient traders were really brave: the did long trips, crossed deserts and mountain ranges and seas, had to pay duties and road taxes to kings and often met robbers, pirates and armies, storms, blizzards, diseases etc., and the trade never stopped. No wonder why today's traders in the Middle East consider the trade embargos just as opportunities. I would be interested to read more of the ancient trade.
Lexham Bible Dictionary has at least one reference to it, but the link won't work until the book is in Logos, and I had thought that Lexham is part of Faithlife:
Roads. Major cities during the neo-Assyrian and neo-Babylonian periods displayed sophisticated paving of processional streets. For example, one processional way found at Babylon (dating to roughly 600 BC) reveals two layers of paving: bricks set in asphalt as a foundation, followed by limestone slabs on top (Casson, Travel, 50).
