Sixth date dating
Tissot, 'By the Waters of Babylon' (1896-1903), The Jewish Museum, New York. Tissot illustrates Psalm 137:1-2: " By the rivers of Babylon we sat and wept when we remembered Zion.
There on the poplars we hung our harps...." Any study of the dating of the Book of Daniel must begin with the dates imbedded within the text.
It is now generally recognized that there were many earlier contacts with the Greeks and Persians, including Greek colonies in Egypt in the mid-seventh century BC and Greek mercenary troops in the Battle of Carchemish in 605 BC.
Also, the names of musical instruments could well be found along with the instruments at the Persian court. Today, linguistic arguments for a late date of Daniel are considered quite weak.
One argument for a late date comes from the observation that apocalyptic literature seems to have been popular between 200 BC and 100 AD.
We still don't know anything about this Darius the Mede from contemporary documents.
Some have questioned the use of the word "Chaldean" in Daniel. It can be translated as either "Chaldean" by race, or as "learned," of the class of Magi (a technical term derived from the reputation of the Chaldean wise men), depending upon the context. In Daniel's day, Babylon was ruled by leaders drawn from the clan of the Chaldeans who lived in the area around Babylon.
