Gussie gets it.
Even so, the best proeminent marble buildings werent that white, they had alot of more decorative paint jobs arround it. even the colums were painted in several colours. The statues are a prime example, they all looked like as closely as a person, paintjob wise.
The ideia, of a white shining cities of classical times is a myth. What we see today, in most artifacts and objects is actualy marble in its raw form, because the paint already wore off.
I recon Ca is doing this to apease and macth this pre concept intheir audience minds.
Allthough i will much like to see something diferent. And yeah Rome Hbo Tv show, is a prime example of a more acurate depiction of it.
