The next stop in the ongoing public art project takes us back to Portland State University campus, this time to the 1980s-era business school building, where Levitated Light hangs in the large atrium facing SW 6th Ave. It's visible from outside, and I just sort of assumed it was a fancy chandelier. Although as you can see here, the lights are actually mounted in the atrium ceiling, and it's not a chandelier at all. It turns out this is a large sculpture by Dale Eldred, who I gather was quite a well-known artist. This is the part where I explain once again that I'm not really an art critic or much of an expert, and my unfamiliarity with his work is not an interesting data point.
I haven't figured out how PSU ended up with a large (but very obscure) sculpture by an apparently famous artist. The Oregonian apparently never reported on in when it went in, nor have any of the paper's art critics mentioned it in the decades since then. So... I dunno. It did show up in someone's interesting list of Portland-area glass art. (I say "interesting" because I may want to track down a few of the other entries on the list at some point.)
