I want to know the answer to the following question:
What type of art is modeled after a supposed Greek bronze original made in the second quarter of the 5th Century BCE.
All the background I'm provided with is that "The type is represented by neo-Attic Imperial Roman copies of the late 1st or early 2nd century, modelled upon a supposed Greek bronze original made in the second quarter of the 5th century BCE, in a style similar to works of Polykleitos but more archaic.". Is that enough to answer the question?
