Archaeologists have long relied on ruins, artifacts, and ancient roads to understand how people traveled in the past. However, a new study suggests that the landscape itself played a much larger role in shaping human and animal movement than previously understood. Researchers used advanced computer modeling to explore how terrain influenced travel, escape routes, and trade activities in the ancient world.
The research highlights that movement in ancient times was not simply about the distance between locations. Instead, it depended on a combination of factors, including terrain, visibility, physical ability, and the type of animals used for transportation. Hills, slopes, and natural barriers could significantly affect how people moved through an area.
To investigate these patterns, researchers led by Chairi Kiourt of the Athena Research Centre in Xanthi, Greece, developed a digital simulation system. The model reconstructs landscapes in three dimensions using real elevation data. It then simulates how different groups of people and transport animals move across uneven ground.
Computer simulations reveal movement patterns
The new approach addresses a long-standing challenge in archaeology. Traditional evidence, such as pottery remains, pathways, and settlement structures, can indicate where ancient people traveled. However, these clues cannot fully explain how movement occurred or how people reacted to steep terrain, limited visibility, or the threat of pursuit.
Researchers tested the model using two historical locations in Greece. One case study focused on the Roman-era fort of Kimmeria near present-day Xanthi. Another examined travel routes leading to the sanctuary of Kalapodi in central Greece.
At Kimmeria, the simulation explored whether the hilltop fort could have served as a safe refuge during emergencies. The model placed fleeing civilians and pursuing enemies within the same virtual landscape. It also divided civilians into different groups, including healthy adults, older individuals, and families traveling with children.
The results showed that people escaping danger rarely followed the shortest path uphill. Instead, movement patterns changed depending on the terrain. Natural features such as slopes and ridges sometimes blocked visibility, which helped civilians avoid those chasing them.
Terrain and transport shaped ancient trade
The findings suggest that the surrounding terrain may have been as important as the fort itself. Hills and landforms could slow down pursuers, interrupt lines of sight, and increase the chances of a successful escape. The simulations also showed that outcomes varied depending on the physical condition of each group.
The research also examined how goods may have been transported to religious sites such as Kalapodi. Scientists compared ox-pulled carts with pack animals like mules. While carts could carry heavier loads, they struggled on steep terrain and moved more slowly.
Pack animals, in contrast, carried lighter loads but traveled faster and handled rugged landscapes more effectively. The model suggests that in mountainous regions, transporting smaller loads with animals may have been more efficient than using carts.
Researchers emphasize that the simulations do not recreate the past exactly. Instead, the system allows scientists to test realistic scenarios. The study indicates that in ancient societies, travel decisions were shaped by terrain, visibility, physical capability, and the type of transport available.
