What did Rene Proportion do to develop proportion?

Answer 1

There is nobody by the name of Rene Proportion who was directly involved in the development of ratios and proportions. It is impossible to trace the origin of the concept of ratio or proportions, since the ideas from which it developed would have been familiar to ancient literate cultures. For example, the idea of one field being twice as large as another is so comprehensible that it would have been understood across societies.
