I really wanted to post a little timeline. Earlier I actually started typing a comment suggesting that perhaps Da Vinci used the same model for both paintings, then erased it rather than posting it… I forced myself to ‘bite my tongue’.
The fact is that I am not used to letting students take ownership of their learning in this way. I want to ‘teach’ them… isn’t that my job?
But if I had put that “perhaps Da Vinci used the same model” post in after the 5th or 6th comment, would the other comments have followed?
