A class of "wise men" is described as existing at Babylon, foremost among whom are the Chaldaeans; they have a special "learning," and (as it would seem) a special "tongue;" their business is to expound dreams and prodigies; they are in high favor with the monarch, and are often consulted by him.

This body of "wise men" is subdivided into four classes--"Chaldaeans, magicians, astrologers, and soothsayers"-- a subdivision which seems to be based upon difference of occupation.

It is not distinctly stated that they are priests; nor does it seem that they were a caste; for Jews are enrolled among their number, and Daniel himself is made chief of the entire body.

But they form a very distinct order, and constitute a considerable power in the state; they have direct communication with the monarch, and they are believed to possess, not merely human learning, but a supernatural power of predicting future events.

High civil office is enjoyed by some of their number.
Notices agreeing with these, but of less importance, are contained in Herodotus and Strabo.
