File talk:Paris bordon - retrato de alvise contarini 04.JPG

Attribution

I do not understand what is the source that argues this is a guy called Alvise Contarini. That is, whether or not there is a study and why its authors have explicitly identified the man in the portrait as Alvise Contarini (not to be confused with the Doge and the Diplomats, both born well after the painting was made).
