I still haven’t read  articles that make the point of the importance of materials to the artwork itself that are convincing enough for me to change my stance. Bosch’s choice to work in oil paint, rather than tempera, had more to do with technological invention in media, than grandstanding through binder choice. If an artist brought cultural acceptability to a media (ie Ansel Adams and photography), the choice of media would be important, but for the rest of us, it seems immaterial.  It’s a rabbit hole that distracts from the work itself.
