To me personally, as a former History and Art teacher, who also studied animation, it’s not about why really, it’s about could it be done? Things like this will always fall under “artistic impression”, as no matter the technology, we ourselves are only limited to the present, so we could never recreate something from the past 100% accurately. Unless we somehow figure out how to view the past in real time (which by the way is theoretically possible, maybe in the future). So best we can do is recreate parts of history to give us an idea of how it would have been. In the end it’s really just playing around for our own curiosity/ satisfaction/ etc.
