So just who did invent the bike?
Well some would claim that it was Gian Giacomo Caprotti, a pupil of Leonardo da Vinci who is said to have drawn a sketch which was later installed in a church window in Stoke Poges in the 16th Century. This shows a naked angel on a bicycle-like device (also the first cheap bike shaped object , or BSO maybe?).
The authenticity of the bicycle sketch is vigorously maintained by followers of Prof. Augusto Marinoni, a lexicographer and philologist, who was entrusted by the Commissione Vinciana of Rome with the transcription of da Vinci’s Codex Atlanticus.
What do I think?
Well for a start it only has one wheel not two and I doubt very much that the cherub would get anywhere trying to ride that hobby horse style. So whoever drew it and whatever it is, I doubt very much if it is a bike and I certainly would not call it that.
