I found this sentence:
Ancient Greece was a civilization belonging to a period of Greek history that lasted from the Archaic period of the 8th to 6th centuries BC to the end of antiquity (ca. AD 600).
on this wikipedia page.
Is this sentence correct?
I wonder what of the 8th refers to. Did the ancient Greece last from 8th BC to 600 AD? Or did it last from 6th BC to 600 AD? Did the author mean that the Archaic period lasted from 8th to 6th BC?
