"3 Kalki 20:10, 16 December 2007 (UTC) with a strong lean toward 4. this is now recognized as a misattribution; as noted on the Leonardo da Vinci page: "This quotation, which cannot be found in any of da Vinci's writings, was first used in print (and misattributed to Leonardo da Vinci) in a science fiction story published in 1975, The Storms of Windhaven. One of the authors, Lisa Tuttle, remembers that the quote was suggested by science fiction writer Ben Bova, who says he believes he got the quote from a TV documentary narrated by Fredric March, presumably I, Leonardo da Vinci, written by John H. Secondari for the series Saga of Western Man, which aired on 23 February 1965. Bova incorrectly assumed that he was quoting da Vinci. The probable author is John Hermes Secondari (1919-1975), American author and television producer." I would probably be willing to use it here, but only with a clear designation of the actual source, which remains somewhat undetermined at present. ~ ♞☤☮♌︎Kalki ⚚⚓︎⊙☳☶⚡ 23:42, 16 December 2020 (UTC)"
