What is the Latin title of the architectural treatise that articulates principles of safety, function, and beauty?

• A. The Elements
• B. The Republic
• C. De Arhitectura
• D. De Architectura

Answer: (D)

The treatise that articulates safety, function, and beauty is Vitruvius’s De Architectura. It outlines three enduring criteria for architecture: firmitas (durability and safety), utilitas (function), and venustas (beauty). The phrase safety, function, and beauty directly maps to these concepts, so the Latin title being asked for is De Architectura.

For context, the other works listed are not architectural treatises: The Elements is about geometry, The Republic deals with justice and the ideal state, and De Arhitectura is a non-Latin spelling variation found in some languages, not the classic Latin title used in scholarship.
