The drawing and text are sometimes called the Canon of Proportions or, less often, Proportions of Man . Leonardo based his drawing on some hints at correlations of ideal human proportions with geometry in Book III of the treatise De Architectura by the ancient Roman architect Vitruvius , thus its name.

这图和其上附言有时又被称为 Canon of Proportions ，或者偶尔也叫做《人体比例》，创作该图时，列奥纳多参照了古罗马建筑家维特鲁威的《建筑十书》的第三部书中所描述的人体黄金比例几何学，故画也因此得名。
