Where are their Bones?

[TranquillityBase]

This is about one of my favorite subjects, one of the many underbellies of Rome.  I read that when they excavated a pit where the dead Arena animals were buried, there were so many that the smell of rotting flesh was still strong.

But about the poem, my only gripe is "fighting for their lives" which seems cliche.  Otherwise, this is a vivid trip to an interesting final stanza.
