Marino Marini, L'angelo della Citta, 1948.
Marino Marini was a sculptor in Italy in the 20th century. This was the first work I ever saw by him, on the same influential day that I saw my favorite Kandinsky. You see, when you study Florentine Renaissance painting for four months, and then suddenly go to a modern/contemporary art gallery, you tend to get a little floored by what's there--not your typical Leonardo.
So this sculpture, for obvious reasons, floored me (insert penile pun here). It's really an amazing piece to stand in front of, and not just because we all like to see a few blatant phallic references now and then. Those stiff lines and strong curves create an incredible sense of energy that becomes almost overpowering when you see the work in person. And the juxtaposition of the wild-eyed horse with the self sacrifycing doll-like man draw the eye in a continual triangle so that your eye almost gains energy as it looks, darting from point to point.
Often in sculpture of bodies and horses, the musculature is what's of interest. Artists are studying the make-up of these bodies in order to recreate the same muscle shape, tension, and detail. Marini doesn't neglect musculature in this work, or in his others, but I think his interest in more in the shapes themselves and the way he can angle and turn bodies to get a different reaction from his viewer. Compare this to Degas, for example, who also created many works of horses. The scale Degas chooses (much smaller) and the medium (wax cast in bronze) allow-or enforce- his focus on muscle.
Here's another Marini sculpture, this one at his museum in Florence. This more abstracted work shows how far he takes his angular experimentation--and the works continue down this path of abstraction throughout his life.
