What is the period style of Alvin Loving's "Steptehedron"?
I'm writing an essay for my art history class and I honestly don't even know what period style refers to and I can't seem to find anything online thats dumbed down enough for me to understand.
It's a geometric, abstract piece painted in 1970.
Also can anyone tell me what the title means? Google is pretty convinced it's just not a word.
