I don't see how the passage you cite suggests either that the writer knew the earth to be spherical or that it wasn't the centre of the universe. All it states is that both the moon and sun stood still in the sky (I'm quite happy to view that as 'poetic', in the same we talk of sunrise and sunset, when we know it doesn't really move, the earth does. Perhaps the author of the passage knew that too...but I don't see anything in the passage to indicate he does). What is in that passage is perfectly in accord with the idea that the earth is flat, round (like a pizza) and that both the moon and the sun orbit around it.
