In the ancient world, overland travel was slower, more tiring, and probably more expensive than sailing. However, the only way to get to many places was on foot.
A traveler could walk about 20 miles (30 km) a day. He would be exposed to the elements—sun, rain, heat, and cold—and to the danger of being accosted by thieves. The apostle Paul noted that he was “in journeys often, in dangers from rivers, in dangers from robbers.”—2 Cor. 11:26.
A vast network of paved roads traversed the Roman Empire. Along the main highways, travelers would find inns spaced a day’s walking distance apart. Between these were taverns where one could obtain basic supplies. Contemporary writers describe inns and taverns as being dirty, overcrowded, humid, and flea-infested. They were disreputable places, frequented by the worst elements of society. Innkeepers often robbed travelers and included prostitution among the services offered.
Christians no doubt avoided such places as much as possible. When traveling in lands where they had no family or friends, though, they would likely have had little alternative.
