>>13961999Good on you for recognizing the difference in the Vitruvian work.
DaVinci has been recorded in history as performing mirror writing.
It is very likely that the Vitruvian man was sketched with a mirror sketching technique.
DaVinci probably drew each side of the Vitruvian simultaneously, each side with each hand respectively.
Look at the detail differentiation between each half of the Vitruvian, and it appears quite obvious.
