It almost looks like it could have been a poor, early attempt at the “Walking Liberty” model.
US sculpture (and European sculpture) descends from it, but as today, some is better than others. :^)
The Laacoon Group is so good, in recent years one writer has claimed that, rather than just learning from it, Michelangelo sculpted it. If Big Mike had, however, it’s not unlikely he’d have carved in an autography, as he did with his first Pieta.
