Oil paint. Yes.
Your favorite work of art?
my favourite painting is a small oil on wood work attributed to possibly carravagio in his earlier days or a student of him. it's situated with the carravaggio collection in the national gallery in london; side by side with enormous canvases of bright colour, detail, physical impact, this small (almost monchromatic) painting is the one that grabbed my attention above all the others ... and held it. i could have sat for hours and hours watching it, waiting to see the light change and the ripples of rain moving down the high windows shift and change. it was called 'man sat at a tall desk in a dark room' and it was in room 32 of the gallery. just went to get an image but the room is shut for refurb and it's not showing that small painting
it was all about the light.
apart from that, i think, perhaps, i'm more attached to sculpture than painting, even though i love paintings.
have you planted a tree and watched it mature?
