This atlas records a formulated-year using a plain Gregorian Int column, and the house voice convention keeps BC-era dates in prose rather than forcing them into that integer field, so no defensible single year can be written there for this ancient concept. 1What Would Resolve ThisWell-attestedA narrower scholarly consensus date for the composition of De architectura, or a dedicated atlas convention for recording circa BC dates outside the plain Int column, would let this fact be written honestly instead of left blank. 1Discipline NeededWell-attestedClassical scholarship, architectural history 1Question KindWell-attestedDating 1Question StatusWell-attestedOpen 1Reader FacingWell-attestedYes 1Open QuestionDe architectura carries no internal date, and scholarly estimates for when Vitruvius composed the work span roughly 30 to 15 BC.
