From the Codex Atlanticus, this is a letter that Leonardo da Vinci wrote in 1482 to the Duke of Milan advertising his services as a “skilled contriver of instruments of war”. From the translation:
6. I have means by secret and tortuous mines and ways, made without noise, to reach a designated spot, even if it were needed to pass under a trench or a river.
So, Leonardo was pretty much Q from the Bond films or Lucius Fox from Batman. But the artist was in there as well…at the bottom of his list, stuck in almost as an afterthought:
11. I can carry out sculpture in marble, bronze, or clay, and also I can do in painting whatever may be done, as well as any other, be he who he may.
Update: If Leonardo was a programmer, his letter might have read something like this:
4. Again, I have kinds of functions; most convenient and easy to ftp; and with these I can spawn lots of data almost resembling a torrent; and with the download of these cause great terror to the competitor, to his great detriment and confusion.
