Meaning: This quote by Marcus Pollio, also known as Vitruvius, touches on the concept of perception and the influence of context on how we perceive objects and spaces. Vitruvius was a Roman architect, engineer, and author who lived during the 1st century BC. He is best known for his multi-volume work "De architectura" (On Architecture), in which he discusses various aspects of architecture, engineering, and urban planning.

The quote highlights the idea that the way we perceive an object or a space is heavily influenced by its surroundings and the context in which it is placed. This concept has significant implications for architecture, design, and the visual arts, as it underscores the importance of considering the environment and the observer's perspective when creating and experiencing spatial and visual compositions.

When an object is placed under the eye, it is viewed from a particular vantage point, and its appearance is shaped by the observer's position and viewpoint. This idea aligns with the principles of perspective in art and design, where the placement and positioning of objects within a composition can create the illusion of depth and spatial relationships. It also speaks to the subjective nature of perception, as different observers may have varying experiences of the same object based on their individual viewpoints.

Similarly, the quote's mention of the difference in perception between an enclosed space and an open space reflects the impact of environmental context on our perception. Enclosed spaces can evoke feelings of containment, intimacy, or protection, while open spaces may convey a sense of expansiveness, freedom, or exposure. Architects and designers often leverage these contrasting qualities to create specific atmospheres and experiences within built environments, whether it be through the use of natural light, spatial organization, or materiality.

Vitruvius' insight into the relationship between objects, spaces, and perception resonates with contemporary discussions on phenomenology, environmental psychology, and human-centered design. It underscores the interconnectedness of the built environment and human experience, emphasizing the need for design solutions that are attuned to the way people perceive and interact with their surroundings.

In conclusion, Marcus Pollio's quote encapsulates the fundamental idea that our perception of objects and spaces is not static but is shaped by the context in which they exist. This understanding has profound implications for the fields of architecture, design, and the visual arts, prompting practitioners to consider the dynamic relationship between form, context, and human experience when creating and inhabiting spatial environments.
