I do not think that any of us, or ancients, simply see things - we are bound to undertake mental activity that is synonymous with understanding what we see. This understanding is based on what we have been taught and what we add as knowledge during our life.
The ancients worked within a background and context that differs radically from ours. Nonetheless they considered their view and perception to be valid and accurate, just as we would say today, for example - look, anyone can see the sky is blue. We would add nowadays, the sky is the atmosphere covering the planet and light from the sun falls on it, etc etc and thus we understand why the colour is what we observe. The ancients would have discussed it otherwise.
I suggest that debating the difference in perception of the material may be a waste of time. If however, someone says the ancients did not have a modern understanding of a blue sky, therefore they did not worship God and lived by faith, then we would show these moderns they indulge in error.
