Scholarly estimates for the date spread across the middle centuries of the first millennium CE, and the region of composition is not established either. The text is the most comprehensive surviving shilpa shastra treatise, so the answer would anchor the dating of the tradition around it, and at present the atlas can only record the spread.
What would resolve this A dated inscription or a dated building whose plan, proportions or terminology can be matched to the Manasara's prescriptions specifically rather than to the shared vocabulary of the shilpa shastras. A critical edition establishing the relationship between the recensions would narrow the region.
