When was a curtsey made?

Poses of obeisance have been made since any one person has perceived another to be superior in any way. The bow and the curtsey has evolved from these , and I'm not sure when the current modified curtsey came into use , no doubt sometime in the Victorian Era , when overly courtly gestures became seen as flamboyant , and also the changing of France after the Revolution , when Royalty fell out of favor.
