"An easy approach to the walls must be provided against: indeed they should be surrounded by uneven ground, and the roads leading to the gates should be winding and turn to the left from the gates"

This quote by Marcus V. Pollio suggests that the walls of a city must be surrounded by uneven ground, and the roads resulting in evictions need to be winding and rely on the left from the gates. This is an easy technique to providing security against prospective attackers. By having the roads winding and turning to the left from evictions, it would be more difficult for assaulters to access to the city. The uneven ground would also make it difficult for assailants to approach the walls, as they would have to browse the uneven surface. This approach would provide an extra layer of defense for the city, making it harder for assailants to gain access. This quote by Marcus V. Pollio is a reminder of the importance of having strong protective steps in location to safeguard a city from possible attackers.
