Meaning: The quote by Marcus Pollio highlights the significance of selecting a suitable location for building a city. It emphasizes the importance of a healthy environment, specifically focusing on the geographical and climatic aspects. The quote suggests that when establishing the walls of a city, careful consideration should be given to the location in order to promote the well-being of its inhabitants.

Marcus Pollio, commonly known as Vitruvius, was a Roman architect and engineer who lived during the first century BC. He is best known for his work "De architectura," a comprehensive treatise on architecture that encompasses various aspects of building and city planning. In this influential work, Vitruvius discusses the principles and elements of architecture, including the selection of a suitable site for urban development.

The quote underscores the significance of choosing a healthy location for a city, particularly focusing on several key factors. First and foremost, the selection of high ground is emphasized. This is crucial for various reasons, including protection from potential flooding, improved visibility, and enhanced natural drainage. High ground can also provide a sense of security and fortification, which are essential for the defense of the city.

Additionally, the quote mentions the importance of avoiding locations that are prone to fogs and rains. This reflects an understanding of the detrimental effects of damp and humid environments on the health and well-being of the population. Such conditions can lead to the spread of diseases and discomfort, making it essential to choose a location with a favorable climate and minimal exposure to excessive moisture.

Furthermore, the quote stresses the significance of selecting a location with a temperate climate, avoiding extremes of temperature. This indicates the importance of a moderate and balanced environment that is neither excessively hot nor cold. A temperate climate can contribute to the overall comfort and health of the residents, reducing the risk of weather-related health issues and providing a more pleasant living environment.

Vitruvius' emphasis on the health and well-being of the inhabitants aligns with the broader concept of "salubritas" in Roman urban planning. Salubritas refers to the careful consideration of health-related factors in the design and layout of cities, reflecting a holistic approach to urban development that takes into account not only architectural and aesthetic considerations but also the physical and mental well-being of the population.

In conclusion, the quote by Marcus Pollio encapsulates the essential principles of selecting a healthy location for a city. It emphasizes the significance of high ground, favorable climatic conditions, and the avoidance of environmental hazards. By prioritizing the well-being of the inhabitants, the quote underscores the importance of thoughtful urban planning and the creation of environments that promote health, comfort, and overall quality of life.
