Keywords: Leonardo-Fahrrad.jpg Bicycle model constructed based on an alleged drawing by Leonardo da Vinci or one of his pupils now widely held to be a hoax Photo by Erik Möller WARNING the following comment is OR Mandy 00 13 13 January 2008 UTC The page on which the bicylce drawing is found has a drawing which is by Leonardo There are a number of other images on the page One of the pictures is a very poorly drawn profile of a face The drawing of the face is NOT by a pupil of Leonardo because it is drawn by someone with no training in either observation of the human form or in handling a drawing implement The evidencce for this is that as in the drawings of most young children the eyes are up near the top of the head the face has features but no appearancce of having a skull Secondly the hair has been drawn by someone with a small hand which can be judged by the radius of the arcs inscribed in a scribbly way dictated not by the shape of the head but merely by the mechanics of the hand without consideration for form The bicycle shows all the same characteristcs as the face It appears to have been drawn by the same hand and in the same scribbly manner Like the face it has a serious problem with the proportions the gear and pedals are drawn so large that they stick down beyond the wheels of the bike Leonardo often simply omitted from his drawings some of the most basic mechanical components eg some of his inventions will not work when constructed as drawn because he has left out a couple of angle gears or even the lever that makes a thing operate but he did not draw things that were seriously disproportionate If a part needed to be shown in greater detail then he drew an additional drawing of the part Moreover Leonardo drew decisively He did not draw by using a series of short uncertain lines or a series of scribbles in the hope that one mighht fall in the right place His steady and expert hand did not drive the implement that drew this bike In my POV it is not a hoax because there is no attempt by any clever person to make the drawing look as if it was done by the master It looks as if it has been done by a kid perhaps inspired by Leonardo's drawings of both figures and mechanical objects The date of the two images could be determined by the form of the bike Mandy 00 13 13 January 2008 UTC Leonardo da Vinci Mensch - Erfinder - Genie exhibit Berlin 2005 Bicycles by Leonardo da Vinci Models of inventions by Leonardo da Vinci |
