With Emma and Julia Campbell in front of you, look to your left. There’s a fascinating video projection on the screen, showing the thoroughly absorbing process of making plaster casts. It’s so interesting, and definitely worth pausing to watch. When you’re ready, leave the gipsoteca and climb back down the four steps, entering the small room on your right. You should now be looking at one large work on your left: The Tree of Life by Pacino da Buonaguida.
