How is Leonardo da Vinci a renaissance man?

very simple,....... as a matter of fact he lived during that period,...that period of time is explained as "Renaissance"......the early period of the organization of the church ( catholic ) and those people who were not catholic who lived inside and outside of that which was governed by the church. this was a posthumous period after the Templars became a known group and then were disabandoned and no longer recognized among other details and campaignes
